I just ordered Spinosad and a spreader agent called SM-90. That will be my next round of attack against the whiteflies, as my Met-52 is almost gone.
I've contemplated Malathion and Sevin, but I don't have a cartridge respirator or a spray suit, which would cost more than the non-chemical spray. Plus, the whitefly damage is not apparent until the fruit ripen. So I may be stuck eating my tomatoes and not selling them. But at least I will have something I want to eat.
