    Why bother to spray the underside of the leaf? When the caterpillar eats the leaf it eats both the top and bottom.

    • @FamilyPlotGarden
      @FamilyPlotGarden  3 года назад +3

      The affect on the plants is that the caterpillar must eat some of the plant that has Bt on it. So you will have a very small amount of insect damage. once the caterpillar ingests the Bt it will almost immediately stop feeding and die.
      The Bt is a stomach poison to caterpillars. It does not have any affect on humans or other mammals or other animals.
      With any other insecticide you need to make sure you are applying the correct pesticide for the problem. Also, be aware that you need to be aware of what you don't want to kill. For example, if you are trying to grow milkweed for monarch butterflies don't put Bt on the milkweed. It will kill the monarch caterpillars.

      @angellee5108 2 года назад

      From cucurbitan…..the bitter toxins in bitter gourds. It causes nausea, diarrhea and can kill humans. Look up bitter gourd poisoning. You will also get sick of it is not washed off properly because it can leach into the soft flesh of fruits. So don’t use it on tender skinned things like berries or beans or the foods you eat the skin of as a precaution. Soaking your veggies in water can leach a good portion of the toxins from the skins.
      Will it prevent bugs from eating it? Yes. Can it also make you sick? Yes.
      My suggestion is to plant your own bitter gourds and make your own without any processed chemicals. It comes from the juice and it’s so bitter that one gourd will go a very long way. Just make sure you wash the skins off and leave them to soak in some water until they are sweaty clean. You always notice a film on home grown veggies. Make sure they squeak.
      Remember that this is a poison, but a natural one used in nature to deter pests from eating the gourds when the seeds are viable. It’s the cold season now……go buy some gourds to use next year and save the seeds so you have your own supply.
      Good luck to you all as we try and provide the best for our lives and families. Remember that people lie…..it is just as toxic to humans as to bugs without precautions.
      Think of it like soap….because in some cultures it is used as soap. You must wash it off.

    • @FamilyPlotGarden
      @FamilyPlotGarden  2 года назад +3

      Bt kills caterpillars, but it does not kill other insects. Bt (Bacillus thuringiensis) is a bacteria that produces a protein that is activated in the high pH gut of a caterpillar. The protein then breaks down the digestive tract of the caterpillar which causes it to die. There are several strains of Bt. Another strain is used to kill mosquito larvae. Here is an info sheet from the National Pesticide Information Center that has a lot more information: npic.orst.edu/factsheets/btgen.html

    • @FamilyPlotGarden
      @FamilyPlotGarden  3 года назад

      Carpenter ants are hard to control. The insecticide needs to be applied inside the nest. Baits can be effective, but they are of limited use. It is probably best to hire a licensed pest control company that has experience with carpenter ants. Here is a publication by University of New Hampshire Extension that goes over some of the details: extension.unh.edu/resources/files/Resource000530_Rep552.pdf

      It does. The great thing though is that caterpillars only seem to do one thing in life: eat. If the Bt was on the plant for only a few hours any caterpillar that has been feeding on the plant has ingested some.

    Do they also eat the tomatoes too? Two years ago I spotted these scary looking Horned Tomato Caterpillars and also saw them in the “super sized” Moth stage! 😳 I didn’t really see a lot of damage to the leaves but they literally feasted on my tomatoes! Or... do you think there were “2” culprits? Last year I didn’t plant anything but my Great Grand Daughter found one along the far side of my house & ever so sweetly brought it to me! 😂 I do have wild Strawberries growing around the entire foundation of my home. Any advice would be greatly appreciated. I honestly miss my tasty home grown (on my deck) delicious tomatoes & I’m not willing to share with these critters! 🤗

      The horn worms usually don't eat the fruit but they will defoliate a tomato plant in a day or two. Other worms do like the fruit like the tomato fruit worm and corn earworm. All of them are effectively controlled by BT. I just watch for damage or the horn worms' telltale droppings - they look like small hand grenades - then spray. If I think there is only one I will just find it and pick it off.
