Thanx.
I did a search and wonder if this class of pesticides can be found at retail stores? All I found was a couple of online sites, Amazon and eBay.
If it is easily found at retail stores, I will not prepare unless I find an infestation. However, if not, I would lay in a supply beforehand, just in case.
We have a crop consultant/entomologist, and he has consistently told me to use malathion in the garden, as that is about the 'safest' insecticide in that the human body does not metabolize it. Bifenthrin is labeled for just about every kind of vegetable, but you have to be more careful and not use it more than twice during a growing season, and not anytime close to harvest.
My favorite insecticide is Fertilome's Triple Action Plus, which is neem oil, and approved for organic gardening. It is an insecticide/miticide/fungicide. It is wonderful to use on tomatoes and peppers and I highly recommend it.
Good luck with your garden!
