With so many choices on the market it gets difficult picking the right product. Most of us choose a product that is rated for crabgrass control.
The Ginja categorizes pre emergents into three categories.
Group 1 - General Pre emergents with Anti-rooting technology
Prodiamine
Isoxaben
Combined products with Trifluralin (used in preen, prevents rhizome shoots from grass) and Isoxaben (snapshot)
Group 2 - General Pre emergent with anti-rooting and post emergent control for crabgrass
Dithiopyr
Dithiopyr will control crabgrass up to the 3 leaf stage making dithiopyr a valuable spray. The marketing is a little deceiving. Although it does act as a post emergent spray up to the 3 leaf stage for crabgrass and some winter annuals it does not provide any other post emergent services for weeds post germination.
Dithiopyr has excellent anti-rooting properties. It permeates into clay very well. I find it doesn't work as well as an over winter product because of the permeability and I don't recommend it for sandy soils.
Group 3 - General Pre emergent with anti-rooting and post emergent control for annual and biennial weeds
pendimethalin - excellent anti-rooting pre emergent with a post emergent control that kills simple broadleafs. the kicker is the post emergent control disrupts stems of annuals and biennial weeds before they leaf making this a very valuable tool for people with annual and biennial broadleaf weed issues. Sprays are far more effective than the granular counterpart for post emergent control. Pendimethalin will stain.
Mesotrione - Pre emergent properties and a broad list of annual and biennial post emergent weed control. This is a great tool for someone who intends to overseed there lawn. I recommend 2 applications before the overseed. Be sure to pick a warm season or cool season grass that's on the label that won't be effected by the product.

Pendimethalin has a tendency to STAIN. Also note the post emergent control for pendimethalin 2G states "pendulum 2g controls weeds as they germinate but will not control established weeds. Therefore, areas to be treated should be free of established weeds. For the control of established weeds, pendulum 2g may be used in conjunction with herbicides registered for postemergence use.

where can I find Dimension in a smaller bottle-all I can find is 1/2 gallon,from the dilution rate something like tbsp/gal this will last me forever
they do that because they don't want home owners buying it at concentrate. the 1/2 gallon is about the smallest you'll get it. they used to do a 32oz jug but I haven't seen it in a while.
Thanks for breaking down the different pre emergent herbicides . The benefits and the problems you may have with certain ones. I know where i am at with bermuda grass is my main turf grass, that Tenacity is not an option. But the others are. Thanks again.
You're welcome. Thanks for the comment!
Great info as always Ginja.
Thanks Steve! really appreciate you spending time to watch my videos
As always a great vid.
As a Swede, I have to ask if there is any organic alternative, because these products are difficult to obtain outside the US? Cheers!
yes there is. Corn Gluten meal. there should be plenty instructions on google for rates. Thanks for watching! Love the Swede's!!!
Excellent!! Instant like.
In meds like antibiotics there is something called synergistic effects. This is where it's possible to use less antibiotic if two are used together. They give a greater effect than if you added the separate effects. So you can use less of each one.
Has anyone done a study to see if herbicides can have this synergistic effect?
They do. It's mostly salt and negative effects on foliar response.
By far the best video I’ve seen on Pre-Emergents. Thank you!
Thanks! Really appreciate you watching and commenting.

I know this is very uncommon or unadvisedly but I used tenacity for spring seeding of KBG/PRG and it was the best think ever. I’m about 5 weeks in and it’s already nice and full with 0 weeds. Now it’s just maintenance from here
It is super common and the primary use for tenacity!!! It's fantastic
@@pestandlawnginja So you are saying the tenacity is ideal to put down as a primary pre-emergent. I am going to order a bottle to have on hand.
Pre Emergent For President!

Thank you, Ginja. Your videos are so helpful.
You're welcome Ryan, thanks for the love
Best lawn service videos out there man. Killing it with knowledge
Thank you! Really appreciate all the support

👊😄
early spring 2019 I used a pre emergent crabgrass preventer and we've never had such a beautiful lawn. The bag was white with black lettering. It said crabgrass preventer as a lable and one bag of granular material covered 10,000 sq ft. Couldn't find it this year so we used Scots Crabgrass pre emergent and our lawn is inundated with dandelions. Do you have any idea who made the product we used?
not a clue hahaha. so many products out there. Most likely pendimethalyn or dithiopyr.
WOW Professor Ginja,
Thank you! What an astounding video & presentation of complex info! So much of this is over my head so I will have to listen to this 2 or 3 more times and take notes.
Just outstanding!!!
V/r,
Eric
Thanks for watching Eric. You'll get it! Takes a little time to figure out all the vocabulary
Incredible overview of the active ingredients... I've watched a few of your vids but subbed just because of this one!
Thanks Jamie! Glad to hear you found value
Great overview! Very interesting point about switching it up. I hadn't heard that before.
indeed! Thanks for watching Jay!
Used HJ every 6 months, give or take, for several decades both in my yard and most of my mowing customers yards. Always went heavy and early in Bermuda yards but had to wait until after overseeding and germination for the fall app with fescue, usually late Oct/early Nov in OK. Hit it again in March and had very few weeds to deal with after a full season of Barricade.
great feedback Jim. thank you
I still say Lucky Charms is the best value at $3/bag. Throw. it. down.
Always a good option 😂😂😂👉👊
@11:45 The 8oz Tenacity bottle full-strength covers one acre. Great comparison video. This is the best and widest overall comparison I have found yet.
Thanks for this
What preemergent is safe for grazing animals. How long should you keep them off. Thanks
Tough questions. According to the msds no herbicide is recommended for grazing animals
Great videos! Quick question, we live in Iowa and had new sod put in last July and had a some crabgrass pop up in late summer that I just pulled out by hand. Would you recommend using a pre-emergent this spring? With the lawn being so new, I'm not sure what to expect for it's first full year of growth. Thanks!
prodiamine or dithiopyr would be my suggestion. prodiamine if you're ground temps are pre 55 degrees. dithiopyr if your at 55 degrees already.
@@pestandlawnginja brother, I'm taking notes. thanks for your help! I hope making comments and such will help push your videos out there more!
Good advice as usual! I get a lot of grassy annual weeds, crab grass wasn't too bad last year but I really want to take out the POA, foxtail, barnyard grass (and quack if at all possible but I'm probably screwed either way with quackgrass). My goal this spring and summer is to control weeds and make a good foundation for a heavy overseeding and renovation mid August, so the weeds arent causing problems and choking the seed out later on. Any suggestions? I was thinking about doing a 4 month app rate of prodiamine in a couple weeks. And maybe tenacity if it will be needed just prior to seeding in August. Prodiamine is quite a bit cheaper than dithipoyr.
If you have the extra $$ I would do an 2 to 3 month app of pendimethalin and then an app of tenacity every two weeks followed by the overseed on the 2nd or 3rd app.
okay, so I have this "Annual bluegrass" Botanical name: Poa annua; common name: annual meadow grass, Annual bluegrass, Los spear grass, Six week grass; Genus: Bluegrass (Poa). and every year it has gotten thicker, even though I have spent many hours pulling it in previous years. What can I use to kill this stuff? It's 400 times worse this year than last year and not sure what to do. According to my app. I took a picture to identify it, and it's native to Europe and Asia. It says Poa annua is known commonly as both annual bluegrass and poa. The Latin name is derived from the Greek word poa, which is a type of fodder grass. I've been pulling it up by hand, and according to this app, this is one method to prevent infestation again, which I have done every time I saw a new plant come up, but this year it covers, at least, 30% of my yard. It says herbicides may be required but in the fall to prevent the new seeds from coming up. Have you had to deal with any of this? I have Tenacity and Quinclorac XLR8. In previous years I have also used TZone with them. Do you have any suggestions? I did notice the roots are small and shallow. I guess I can breakout the trusty dethatch rake ugh lol It's crazy how much has come up this year; because I spend many hours every summer pulling unwanted weeds as well as spot spraying and full cover spray as well. It's really like a nightmare this year. what will kill what has already grown?
Honestly one of the best channels I have subbed to on YT. Great work Ginja!
Sam, really appreciate the compliment!!!
Awesome video. Thanks for breaking it down like that. I noticed the other day that Prodiamine comes in two different Weed Types. I'm gonna guess you are just taking about Crabgrass so you didn't cover that. In case I have Dallisgrass what is the punchline for it?
msma or cma are the go to. Its a booger of a weed
Pest and Lawn Ginja nice answer however I tried to purchase those two chemicals here in west Texas and the supplier would not sell them to me.
As a was told it could only be sold to golf courses, I said what about a farmer? No dice 😫🛫 what do you suggest?
Great video, remind me of the algebra class lol, Seriously I don't know what happen but crabgrass is taking over my yard despite all the effort this year, So what type of killer can i used to get rid of this shit now Man?
I have a video on how to kill crabgrass. called kill crabgrass, dallisgrass, clover in 5 easy steps.
Something is eating the leaves of my 3 weeks old grass. It’s tall fescue and I noticed that the germinated seeds heads are trimmed in a newly planted area. Any suggestions ?
That's odd........ send some pics on facebook
Hey ginja, it’s a little pricey, but it’s good for picking up a new lawn that never had lawncare service and it’s spring and it’s loaded with weeds, they have dimension w/ lockup... I know dithiopyr has post emergent tendencies but only in the early stages of leaf tiller and that’s where lockup takes over!!! Works VERY well for knock down power and preemergent... I only use it when it’s a new takeover and they have a good base to work with but also has a ton of weeds in all different phases of development!!
Very cool. I'll have to consider it.
You had a video with a special measuring cup that you were using for prodiamine/barricade.......where can I find that to buy??!!
I’m tired of breaking out the scale or trying to remember how many teaspoons per square foot Etc.
Thanks!!! Love the content you are putting out.
Those measuring cups come straight from the manufacturer. I would call domyown and see if they have any for sale
Yo Ginja, I was just in Draper over the weekend for high school lacrosse. We played at Corner Canyon and Juan Diego high schools. They had turf ;-(
I'm in those areas every now are then. turf huh.... crazy
Beautiful weekend!! Beautiful City!!
@@danjohnson6292 ridiculous isn't it. sometimes I forget how beautiful it is until I leave and come back.
great video again! trying to refresh my knowledge and up my game on killing weeds. weeds are like spiders and snakes; the only good ones are dead ones lol
Lawn ginja, i just put down Scotts weed & feed last week after reading the bag i didn't see any of these chemicals you mentioned can i put down one of these products you showed with out any harm to my lawn ? I'm located in Denver, Colo.
If it's just pre emergent and no fertilizer you'll be just fine.
I’m planning laying sod for the backyard, which currently overtaken by weed and crab grass. Which pre emergent should I use while tilling the soil for better results? Thanks.
application should be made after you're completely finished and within 2 weeks of the finished product. I prefer prodiamine at the high rates
You’re getting in the way of the Olympic gymnastics going on in the background. 😄😄😄
👊😂 good call
i think the kid jumped into his head 🤣
I'm not sure if my problem would be included with this list but I have thistles spreading into my lawn from the unmaintained pasture next to it. Any suggestions? Thanks Ginja.
Hey Kevin! Sorry this comment went un replied. Thistle is best managed by a split app of prodiamine and using speedzone to spot spray. It'll take 2 seasons to filter out. be sure your watering properly the entire season to get the full use out of your pre emergents.
Great vid
My question is this. I overseeded last fall, and its now a solid 5 months since KYB and Rye germinated. Its time to prevent crabgrass, so Is my grass mature enough to handle Prodiamine? Or should I put down Tenacity?
I have not applied ANY pre emergent at all ever.
I did throw down more seed 4 weeks ago as a winter experiment to create a thicker lawn, but I am more focused on the young KYB and if prodiamine will hurt its root growth.
Thanks
If you're still in the process of overseeding I would recommend you stick with tenacity. however, even tenacity isn't rated for newly emerged grass 😒. You'll need to hold off a bit if you want the new seed to take and stay strong.
With using pre emergent one of the benefits in using them specifically for gardens it will allow to significantly help with weed control when it comes to using starts.
absolutely! Be sure to read the labels. Many pre emergents are not garden safe.
for the last 2 years I have been applying 2 apps of dithiopyr on 4/15 and around 6/10 with great results- no split apps. Prior to that I had terrible crabgrass. Do I stick with the same plan or consider 1st app of prodiamine and 2nd app of dithiopyr or do something even different?
It's a great product. If it isn't broke dont fix it. I would watch the ground temps is all. They'll vary every year.
Hi Ginga, so glad you made this video. I am faced with helping a friend with an acre yard currently overrun with Dallisgrass, crabgrass and buttonweed. I treated with Blindside and MSMA for some current control but my concern is next year. I am not sure there is much Bermuda to push so am considering over seeding in mid May next year. My concern has been about the need for pre-emergent to help control the excessive weed germination but also need to be able to germinate the new Bermuda. Tenacity may be the answer. I am in Greensboro, NC area so crabgrass will likely be germinating by mid-March. When should I apply and will I be OK over seeding with Bermuda? After first year, prodiamine would be my choice in Feb. Thanks for all your GREAT videos and sharing your expertise.
Unfortunately Bermuda doesn't play well with tenacity. Check the prodiamine and dithiopyr label
Great video and detail...thank you. I am in Charlotte with 2/3 acre lot and since it is now April I did not put down a pre-emergent yet. is it too late to do a PE? Can I just use the Tenacity now and then start with PE next year?
I have POA annua that I need to address this fall, can I use tenacity after I aerate and overseed? Or do I have to forgo seeding all together and just use prodiamine or Dimension?
Thanks again for the great content.
Tenacity works great for POA. Just keep in mind you'll need to do back to back applications within 2 to 3 weeks.
ok I don't have a spreader. I want to spread the stuff by hand and can't imagine out how densly to spread it. Is there any way to communicate how densly you should spread it?
Gosh. That's difficult. It needs to be spread at so many lbs per 1000ft2. The more precise you can be the better cost savings and efficacy.
This may be a long post sorry...
Alabama, Zoysia, I started treating my lawn myself 2-3 yrs ago. I've always had a poa problem and noticed some crabgrass this year. I put out half rate of Dithiopyr in Feb and half rate of Scott's Halt yday...I started thinking y'day as I bought Scott's Halt.
Would it hurt if I put out all three types of pre-ems all year? I'd buy the bags at my box stores that have NPK so I'd get the minerals needed.
You think this would be a great idea for my poa problem?
Great question. I would alternate them yearly. Zoysia can be really thick and it can be difficult to get the pre m where it needs to go. be sure to focus on application rate and also watering sufficiently to get the pre m down where it needs to be. If you were going to do a dual app I would do prodiamine late fall and late winter and dithiopyr spring as the temps get into the 50's.
Ginga! Great Content😁 I live in Texas on the line between zones 7&8. I have Centipede grass and I’ve read prodiamine can be a problem. Atrizine and Simozine seem to be the best but I keep searching for pre and post emergence with these as the active ingredient to no avail. What would you recommend?
Question: I live in AF/Lehi area. Did you buy the snapshot 2.5 locally? If so where? I have only seen options online. Thanks for all the vids
DoMyOwn.com has a facility in West Valley. That's where I got it.
Been waiting on this movie ive been confused
fingers crossed I was able to help!
I bought Tenacity, Serfactan and Lazer. Do I want to water it in, or apply it when there is no rain expected?
it needs to dry if you use it as a post emergent and then you need to water it in.
I use IFA's 4 step program... is their step one crabgrass premergent adequate or should I use something in addition?
It's adequate. the granular size is large so you won't have as good of coverage as a standalone pre m. if it's worked in the past don't change it.
Ginja! I'm planning on dropping an application of dithiopyr in the next week or so. (I'm in ohio and our cold temps are dragging on over here) But I plan to overseed in the fall, the question is should I do a app of tenacity in summer or just fertilize and put down with the grass seed?
I would do an app of tenacity then a followup app of tenacity with the over seed two weeks later
Ginja,
Love your videos. You do a fantastic job. I have a question:
I live in Oregon cool season grass (perennial rye grass with some fine rescue) I have two areas in my house front lawn looks amazing. I had some poa problems in the spring because I aerated and seeded last fall 2018 and the seed I used had some some percentage of other weeds in it. I am assuming it was poa. I removed those areas and put new sod and prodiamine(split app) and looks amazing.
In the back I choose to leave the poa and do prodiamine and the lawns looks great but I can still see the areas with poa. I have to make a decision. I can’t use prodiamine because I reach my yearly max. I am not going to aerate or seed.
My question is: if I use tenacity as a blanket application would that take care my poa problem or I am better off removing the areas with poa, add new sod or seed and blanket spray tenacity? Do I need to do a second application of tenacity 3 weeks after sep ? Do I need to add an ionic surfactant? If I heard correctly I need to wait 12 to 24 hours to water in tenacity? Sep 1 is when I am expecting temperatures to come down to 70 degrees.
Another option was to use Dithiopyr 0-0-20 granular without removing the areas with poa. Or I can remove the poa, put new sod and then apply Dithiopyr?
Any help it will be appreciated. Thanks in advance.
Personally I would do two to three apps of tenacity and use dithiopyr
Pest and Lawn Ginja thanks for the reply. So what are u saying is to do Dithiopyr on Sep 1( my temps will be at 70 degrees) and follow by tenacity? Should I wait a few days ta apply tenacity as a blanket application?
What about water this products in? If I apply both on the same day can I water both in or wait 24 hours and water them in? Thanks in advance.
And now tenacity is twice the price...
Checkout meso 4sc . Generic tenacity
Do you wear a mask when spraying prodiamine? Thanks
The label doesn't require it with the product we use.
I live in NW Ohio. I put grass seed down last September. Can I use preemergent now or will it hurt the seeds from taking root thus i wasted my time and money seeding in the previous fall? Thanks. it is early March now.
It all depends if the grass completed the germination process. You would commonly know this if the grass has grown in. Here's my 2c. pre emergents can stunt root development. If you had a lot of weeds in the past few years it may be worth putting down a pre emergent. but..... if you don't mind treating the weeds as they come it would be better for the development of the grass. The risk you run is there are certain types of weeds that will need to be pulled by hand as they will not be effected by herbicides.
@@pestandlawnginja Thank you. I am so impressed with the quick response. I shall use your advise.
@@janis143 caught me at the right time Janis!
If I didnt know any better. I would say that you are in Norther Utah... If so, what is the lay down cut off for pre-emerg
It's always about soil temps. It's commonly too late by april 15 to april 25 IMO
Do ganular pre-ems have a shelf life? I have a couple of sealed bags left over from about 2 years ago.
I'm sure they do, but i'm fairly confident it would take a very long time given that pre emergent is water insoluble and takes soil microbes to break it down.
What a great video! Thank you for the review!!! Great video to watch over and over again.
Glad you enjoyed it!

@@pestandlawnginja what is your email address to reach you? Got some questions about gimbal camera unit
@@dronemaddness5148 hit me up on facebook. Easiest way for me to track all the replys
What if I put my pre em down when soil temps were between 35-40? Will it be ineffective ?
Prodiamine IMO does the best in those colder temps. dithiopyr will do well as long as it doesn't get too much rain to push it too far into the soil. Most pre emergents are not broken down by cold weather. Most are broken down by soil microbes. Hotter the weather more microbe movement.
HI Ginja,
I put some pre emergent along which comes with some fert when the ground was still frozen about a 3 weeks ago.
I am now sacred to put that again once temps hit 55 as it might burn the lawn, what do you think i should do here?
Pre emergent in and of itself has zero burning capabilities. Now, if you're saying that you put down a bag of pre emergent fertilizer there is potential of burning. Watch my video I posted today on nitrogen. Figure out how many lbs per 1000ft2 you put down and do some math. If the bag says 20.2.4, for example, take the first number (which is the nitrogen) and divide 100/20= 5lbs. that 5lbs of product per 1000ft will equal to 1lbs of nitrogen per 1000ft2. Burning occurs after we reach above 1.3 to 1.5 on average area dependent. what gets confusing is if your primary ingredient is Urea it's a whole different ball game. Urea will lose 50% of the Nitrogen to the atmosphere. So you double those numbers in essence. IMO its a total waste to use urea early spring. Ammonium sulfate is best for high ph and low ph nitrate nitrogens.
@@pestandlawnginja Thanks!
Lawn Ginga, im Chris comming at you from Charleston S.C. I have palmetto St Augustine on sand that I put in last December and have a couple questions. I understand Dithopry, prodiamine and pendimethalin. However, i decided to go early with dithiopyr - max rate granular. Well, the soil was at 45 degrees, but it has rained several inches since application ' like 4 inches +. Do you think that application has "washed out?" Or could I possibly get some benifit? Also, am I too understand that with prodiamine you should mix isoxaben at the 50 degree mark? Any assistance would be appreciated.
dithiopyr is a great product. 4" isn't too bad as long as it wasn't dumping. dithiopyr needs to be watered in with a minimum .5" of water. I try and remind people that it's not un common to water a lawn 2" to 3" per week and the pre emergents sustain just fine. I'm on the fence weather you'll need to re apply. it will all depend on how the water came crashing into the lawn.
Good day Ginja Ninja! I have a Zoysia question regarding pre-emergent herbicides and young Zoysia. My Zenith Zoysia lawn was seeded the last week of August, 2019. I've mowed once at 1.5 inches, and I'm ready to mow again once the rain stops, again at 1.5 inches. Would you think there would be any chance of harming my lawn if I put down Prodiamine this fall or next spring while the Zoysia is dormant, or do you think the lawn is still a bit too new to risk it? If you feel it is too risky, at what point would you feel safe putting down a pre-emergent? Would it be later in the spring after mowing a few more times before the temps hit ~90 consistently here in humid Central Virginia, or just suck it up and use post-emergent herbicides during the year like 2, 4D and Quinclorac, and start my pre-emergent regimen next fall? Thanks in advance for your time and info!
Great questions. I prefer not to use pre emergents during new stages of growth, other than tenacity which you wouldn't be able to use on zoysia. I prefer to stay free of herbicides for the first 90 days. It's more of a preference than anything. But in my experience the pre emergents can cause rooting issues in the first little while.
Professor Al and Professor Ginga collaboration would be eye opening in mathematical calculations and information for us DIYers. 😁👍👍
ha, love it!!! Thanks for the compliment. made my day
Ginja,
Transition Zone Bermuda. Wet springs, hot summers. Poa is nuts until mid June. Which of these do you recommend for a better poa control? I am fighting an uphill battle, been in the house a little over a year and previous owner didn’t do squat. We’ve made progress but I’m ready for it all to be gone. Used prodiamine this fall/spring.
the better of the bunch in my opinion is dithiopyr based pre emergents. I would also consider a PGR (growth regulator). they've been known to kill poa
I've recently plugged 1/2 of the yard with Zoysia and it even beginning to spread on first year. The only successful treatment I've had for crabgrass is Tenacity, but I wonder if it's safe with zoysia. I've heard both ways. What's your opinion?
Its not safe for use on actively growing zoysia. I've tried used it on zoysia to see and it will stress it beyond belief.
I've cleared several acres of timberland, and now what should be my pasture is a field of nothing but crabgrass. It has completely taken over. I need to get bermuda planted for grazing, but the crabgrass is so thick nothing will grow. While not a lawn, will one of these work? Keep in mind, it's a pasture, so watering isn't an option. It's August, in Texas, can I put something down now to get a start before spring?
bermuda can be a booger to seed. seed germination is very slow moving. if you're in a hot part of texas bermuda will most likely be your best bet. You can always try to plug it one section at a time. once the bermuda gets thick enough it will ward other types of weeds off but it takes time. It's also a needy grass. It constantly grows off the stolon and needs to be scalped twice a year. I think zoysia would be a better choice.
STOKED!!! very informative and definitely cleared up my confusion. I just put down a granular with dithiopyr about a month ago. I need to wait a few more weeks before I overseed.
Perfect!
How would you suggest when wanting to add st aug plugs to a lawn renovation?
Great video and info Ginja! Can you share what you are using to edit? Looks great man 👍
I use imovie. I like to keep it simple.
@@pestandlawnginja thanks Ginja!!
Hi. I know this is an older video but it was very educational to me. My question is I live in HOT Texas and I have a lot of crabgrass heading into October. What do you suggest for an area that stay in the 80s till November. Thanks
dithiopyr would be my choice
do know what crabgrass is called in Australia? i don't think we have it my area GC Queensland 👍🏻
Ha, ask Lawn Tips! He'd know for sure. Fill me in
Thanks and great vid. I love in Northeast and have KBG. Should I aerate in early spring before pre-emerg? Thanks
I prefer to scarify
I just discovered your channel and wow, what a trove of detailed info. Historically, I haven't done much other then apply weed/feed fertilizer in Spring/Summer/Fall because I don't have irrigation and I'm on a full Acre in New England so I've always relied on Mother Nature for watering. Unfortunately, the lawn is pretty weed heavy so I'm considering a baseline dose of Tenacity this October to eliminate the current weeds, followed by dithiopyr later that month and again in the Spring with my usual fertilizing to get something looking somewhat respectable. Does this sound reasonable or would I be wasting my money until I get an irrigation system installed to properly water?
I wouldn't recommend the dithiopyr unless the crabgrass is still in the 2 to 3 leaf stage. Prodiamine is much cheaper and stays in the soil better.
As for the constant weed problems I would focus on a cheap calcium source and try to get some water to hell the grass
What’s your rec for south Louisiana pre emergent?
I have some Demsion but will be getting some prodamine.
Need to lay down some soon.
I’m thinking prodamine now and then demsion later in fall.
What is the time between split apps?
tenacity is NOT a great pre emergent. I would use dithiopyr or prodiamine for a standalone pre emergent. dithiopyr bonds with the soil and where prodiamine is a barrier that can be broken with aeration, dethatching, weed wacking etc
following you awesome videos, im in the northeast. I havent bought it yet.
my lawn is in great shape but I'm at the point where I'm beyond using scotts products.
ryegrass fescure mix in my lawn what do you recommend?
either prodiamine or dithiopyr
Great Vid! I went with Tenacity this year, with a lawn comprised of such a high percentage of weeds, I was expecting more bareness, its only been a week though. Such a small dose makes me question if I did it right though. 2 teaspoons of tenacity from a backpack sprayer for 1000sq ft of lawn sounds right though?
It's recommended at .68 to 1 teaspoon per 1000ft2
Are those the Rockies behind you? I'm in Fort Collins trying to deal with clay soil and crabgrass. Thanks for the info, especially the pricing.
Yes they are! I'm in Utah. very similar conditions to where your at.
Hey I love your videos but have no luck with Scott’s 4 step program for the last 15 years can you help me I live in mass and I no idea we’re to start so much help on RUclips In the more people I watch the more confused I get yo my guy I feel like I can trust the most what information you need my help to help you stand in the right direction I appreciate it thank you very much
Start with checking sprinkler coverage and do a water output cup test.
Next do a soil test to see which fertilizer is right for your soil. I prefer to use Mysoil
good stuff Ginja. Thanks for your knowledge bro.
Thanks Rick! Great to hear from you
Great video Ginga. Saved to my lawn care favorites. What about Barricade? Doesn't that fit into this group somewhere?
barricade = prodiamine
I can't find this stuff anywhere , does Wal-Mart sell this stuff, I asked the girl in frozen foods dept, she said it was by the.corn but wasn't
😂 I have direct links to these products in the description of the video
Which pre-emergent herbicide you recommend to apply if we have reseeded early fall. I don't want to kill the new grass?
I wouldn't use anything other than tenacity 6 weeks after the seeding.
Bro...nice work and thanks for the info!
You bet!
Do you have a recommended spreader for DIY like myself. I had a Scott Spreader from HD and it broke right away made out of cheap plastic with cheap plastic wheels. I would spend more money on a good well made spreader that is accurate easy to use and long lasting.
This is the one I buy

@@pestandlawnginja Thank you! Love your videos. I live in Herriman Utah so you being in Utah is also very helpful.
@@garykarczewski6678 You're welcome!!!
I live in Michigan. I have a clay based lawn, (thanks to the builder removing the topsoil), it has taken 2 years of soil tests, peat moss top dressing, aerating, and post emergent treatments with 2,4D and quinclorac, but I finally have a really nice lawn. However, I had a bad dandelion problem in Spring of 2021 then crab grass issues in August 2021. I did a a major overseed project with 50lbs of KBG in mid September and top dressed with peat moss with a landzie roller, after core aerating the whole 15,000 ft2 yard. What would be your recommendation for a pre-emergent before the soil temps reach 55 degrees? I don't mind spending the money on a good product. I am unsure if I should go with Dithiopyr, Prodiamine, or something else. I am hoping to initially prevent the dandelions, but if a second app in late July would also prevent the crabgrass then I will do that. Whatever guidance you could give would be very much appreciated. I want to try and prevent any of these issues this growing season to allow the KGB room to fully mature to really thicken up the lawn. I also put in an irrigation system at the beginning of September last year so I could have complete control of the watering. Thank you.
Your kid in the background is great!!
Thank you! They love the comments that include them 👊🤩
You keep saying “we need that weed seed to germinate”. If they don’t germinate, problem solved.
true true
Great content. Thank you for posting additional notes in descr and the links in Amazon. I've never seen these in home improvement stores.
You're welcome. I'll be updating the notes as I get more time.
Ginja thank you for all the great videos and helpful tips. You are hands down one of the best lawn care tubers on RUclips. Oh and that beard is really coming along nicely 🤘
Super kind Brent!!! Thank you so much
Great information. appreciate it 👍
You're welcome Jay!!! Flo on my friend
How are your soil temps? How close are you from applying your pre emergent?
My local soil temps are hovering around 50 degrees. It's been snowing and sleeting all week. Most wouldn't think the soil is that warm IMO. We started putting down pre emergent march 1st. I'll be using tenacity and an overseed on my lawn this season so I'm holding off for a bit.
Pest and Lawn Ginja I bought your same soil thermometer. I’ve been testing my temps. I’m looking to apply my Prodiamine next Saturday. It’s a great time of the year. Keep up the great content!
Awesome! I'm shocked at how well it works. Almost a year old and still kicking.
Ned!!!! Oh and thanks for the info!
Ned is back! HAHAHA. You're welcome! Thanks for the comment
These are great vids,
How did you get started in this work?
Thanks B. I sold door to door for 6 years and listened to people's concerns. Dove in after that and learned first hand on the lawns.
Is there a pendethalin that doesn't stain like crazy?
Not that I know of
going to overseed some small areas that need it this spring and use tenacity for pre-emergent. is this also I have a small area of zoysia grass. I s it also ok to use there?
tenacity will stress out your zoysia and possibly kill it. It's not for use with tenacity according to the label. Tenacity isn't a great pre emergent. it lasts about 3 weeks at best.

I think I've screwed the pooch. I put down spectracide before I aerated. How show I go about it? It rained 1 day after applying also. I live in NC
spectracide makes a few different products. I assume you're talking about the crabgrass preventer. if so the rain is a good thing. Helps push it in. You may want to consider another application since you aerated.
@@pestandlawnginja good deal. That is exactly what I used, the crabgrass preventer. I will put down another application and then spray the existing. Thanks.
you'll be good as long as temps aren't too high.
@@pestandlawnginja thanks dude
Hey Ginja, can you tell me what might happen if I were to put my winter rye down in early October then in late November put down a pre emergent. I'm in California and I have bermuda. This was a great vid by the way!
as long as you can water it regularly you'll be fine. if humidity and temps spike you'll need to apply a preventive fungicide. but i think you'll be fine.
@@pestandlawnginja Thanks for the response. I bought my house 8 years ago and always put rye but never a pre emergent. And I fight crabgrass all year long. Lol I am going to try my strategy this year and hope for the best. If it don't work then the following year I will just let bermuda go dormant and load up on pre emergent! Thanks again!!!
Should grass be cut all the way low when applying this ?
3" or less is idea. dethatching and removing topical debris helps the placement and efficacy of the product.
Hey new to the channel, very informative. I recently got into lawncare for my weed infested bermuda lawn. Average temperature in hawaii for my area is mid 80s. Can I put weed killer for grassy and broadleaf weeds before I put a pre emergent?
Should one aerate then power rake or just do one vs the other?
I prefer to power rake first then do the plugs
So I’ve heard not to aerate in the fall, does this apply for fall Bermuda lawns?
It’s a soil issue. Clay is best aerated in the fall. Sand best in the spring
do preemergents halt st augustine or Bermuda from spreading? my lawn is thin in spots?
Trifluralin can do that and that's why its not recommended for lawns
@@pestandlawnginja thanks my man ! i ll try a split dose of prodiamine on my thin south fl lawn .i added it to my weed killer in the beds
