So, my SO found some bugs on one of our Roma tomato plants, and (after trying other things like water+light detergent, etc) sprayed them with the first handy container of insecticide she found in the cupboard, which turned out to be an old sprayer of Ortho Bug B Gon, which contains Diazinon.
The tomatoes are heavily fruiting, so I was worried that there was a waiting period for harvesting after spraying. So I checked the label, which wasn’t more than a sticker with applications and warnings, with no information about spraying veggies, other than the general info that it was “ready to spray, Multi-Purpose Insect Killer, for Roses, Flowers, Shrubs, Vegetables, Lawns & around House Foundations.” The back label contained an Environmental Hazards statement that it kills birds and bees (uh oh). So, the label sanctions the product for use on veggies, but specifies no waiting period. Hmmm
So, off to google, which told me that Diazinon had been banned in 2004. And… not much else, except ads for New Ortho Bug B Gon (now without Diazinon! Yay!) If I search on “Diazinon harvest waiting period vegetables” or similar, I get some hints that there is a waiting period (up to seven days, says one), but “check the label” on the product you used. Ok, been there, done that.
So, will my tomatoes be safe to eat in seven days, or longer? Or should I chuck all the fruits? Or some combination? The product does say its okay on veggies. OTOH, the product was also banned, but I’d guess because of adverse affects on wildlife, which is a common reason things are banned.
