Caption Jack’s Deadbug Brew is an organic that I use and I know lots of folks don’t like it, but I use liquid sevin too. When used correctly, it is fine. I spray late after the flying things have gone to bed.
I used Sevin this year too. Sprayed it middle of the day after the morning pollinating had been done. I thought that was the best time to spray, but it apparently killed all the pollinators that knew about my squash because I didn't have any more pollinated for at least a week.
