      If the max rate is 7lbs per 1k you should be fine. You’re just a little over the recommended limit. In contrast I was over some where between 20x to 40x the rate. Anything you buy at a box store (see Lowe’s/Home Depot) is already diluted to protect from accidents. My friend owns his own lawn care business and worked as an agronomist at a golf course, he mentioned that the professional grade stuff that I purchased is pretty powerful versus what you can buy at Home Depot. For example the tenacity that I have runs at a rate of one teaspoon per 1000. That’s not much!

  • @AlexB-bb5mm

    I think a good way to apply a liquid pre emergent is to break the yard up into sections. So, if you have a 1 gallon sprayer, then you can cover 1k sq feet. If you have a 4 gallon sprayer, then you can do 4k sq feet. With that being said, the granular pre emergent are easier to put down. Im maxed out on prodiamine this year, so I'm going to try the diothophyr pre emergent.

    I bought the five pound container of Prodiamine because the small bottles seemed like a rip off. When I did my first application, I realized I probably have enough of it for the next decade. I questioned my math because it seemed like I barely used any of the big container. I mixed 0.5 ounces per gallon of water and applied one gallon of the mix per thousand feet of lawn, and I'm pretty sure that's correct (I hope). I only plan to do one big dose of it in the spring for a cool season lawn, and my understanding is that for cool season lawns, the annual max should be around 0.55 ounces per thousand, so I'm pretty close to that with my one application. Some folks do a split application using half as much (twice). I also tried spraying all my landscape rock around my shrubs this year to hopefully cut down on weeds in my rocks and not have to use so much Glyphosate. I saw videos where they were using it in AZ for rock "lawns".

    I just put down my Prodiamine as a granular prill with a broadcast spreader. It’s mixed at 0.38% with a 0-0-7 fertilizer that is good for my warm season grass going into winter, so it kills two birds with one stone. It’s also harder to screw up the dosing than it would be with spraying. I believe the product is made by Yard Mastery. The .38% allows me to put down three applications over the course of the year before hitting the maximum recommend application rate for my zoysia, so I get good coverage throughout the year.

    I did the same to my yard in September 2021 . I use the granule. I watered each zone 20 minutes that day. Later we had a lot of rain for 3 days in a row. My grass is dying in many areas. I might apply too much. New spreader but I think it was applying too much. I used Scott rotary Elite at setting 4.
    Should I fertilize in October with Scott Winterguard (32-0-07) ? Will that help? I noticed the noticed the st Augustine is dying but not the centipede in back yard. I have mixture of both grasses. I will hire a Lawn service in February 2022.

      @coachjimvahrenkamp369  11 месяцев назад

      Well a few facts. I moved about a year and a half after this. That year I figured out the rate and had a full healthy lawn. The grass survived and everything was ok.
      That being said. The year I applied a ton of Prodiamine the biggest difference was that plants that weren’t mature with a strong root system died off eventually. The Prodiamine produced what is called clubbing in the shallow roots which inhibited nutrient uptake this starving the plant over time of water and nutrients. Those small grasses turned grey over time and died off.
      One year later it was fine. It’s good to remember that it’s just grass and as you figure things out it gets easier and easier to fix your mistakes!

  • @Midtnfishing937

    The label on my prodiamine says for 1lb/acre, use 1 tablespoon per 1k sq ft mixed with at least 1 gallon of water. I just got a new electric backpack sprayer, and thought I had my walking pace figured out...turns out I accidentally put down twice as much mix as I should have on half of the backyard before noticing. Hopefully it is not going to damage it. I renovated it last year.

      Yeah, during the year the immature grass struggled. I saw clubbing on young roots which inhibited the nutrient and water uptake for the young plants which killed them. Of course I had zero weeds or crabgrass!
      I think on a mature lawn that was pretty thick you wouldn’t see much in the way of negative consequences. I lived in one of the worst areas to grow tall turf type fescue and with the added pressure from the Peoria mine it survived.
      The following summer I put the appropriate amount down for a split application and witnessed some crabgrass germination right in the window between both applications.

    @Cary_Shultz Год назад

    This "translation process" can indeed be a challenge. If one keeps in mind that there are 43,560 square feet in one acre then this "translation process" is a lot easier! The application rate per 1,000 square feet will vary depending on the length of protection you want (for the liquid version of Barricade, the label shows that three months worth of protection takes some 10 ounces per Acre, four months worth of protection takes some 16 ounces per Acre). So, now we know that for three months worth of protection we need 10 ounces to cover 43,560 square feet. But we want 1,000 square feet increments. So, divide both by 43.56. So, 10 divided by 43.56 is 0.23. That tells us that for 1,000 square feet we need almost 1/4 ounce. But math is math! You are not the only one to have made a mistake with the math (ask me how many times I have!).
