Any advice?
As long as the spraying is done late in the evening or very early in the morning I have seen no harm to blooms setting fruit from the bleach spray. Heat and too little water seem to be the biggest culprits in poor fruit set as far as I can determine from watching my own plants over the years. Another thing that can affect fruit set is having too many blooms and growth tips at the same time, which I think may result in not enough plant energy being used for fruit set.

I am still getting some fair tomatoes but with all the damage from whiteflies my fall tomatoes this year are performing poorly along with my fall cucumbers. I am starting to remove a lot of tomato plants that appear unhealthy and are not looking like they will result in much fruit if any. I need to clear a couple of beds for broccoli, cabbage, Brussels sprouts, cauliflower, lettuce, carrots, onions and spinach. I just planted a bed of mustard greens and turnips yesterday. I am hoping the whiteflies are thinning out enough to let them survive when they sprout.

Bill, "I am hoping the whiteflies are thinning out enough to let them survive when they sprout." is that the bug that will eat a 1/2 of a plants foliage overnight, whether it be a flower, fern, pepper plant etc? Seems as if i can control them w/Neem but it is costly and every other night..........too much work - but it sure makes me mad to see the destruction!!
Thanks
Pete

You are probably dealing with some type of caterpillar or grasshoppers. Sevin will work very fast on the caterpillars and may kill the grasshoppers. Permethrin will work on some grasshoppers that were eating my citrus but you have to spray them to kill them.
Since it is getting so many types of plants I would suspect those foliage caterpillars that show up every year and they can defoliate a plant if left unchecked. BT will work somewhat but it is slower and not as deadly on them as Sevin. If I was losing foliage like that I would go straight to the Sevin and see if that stops them but you do have a waiting time after using it.

Sevin kills grasshoppers dead in their tracks.

Thanks Bill, I will look and see if i see any other bugs than the swarms of little white things - i have seen a few grasshoppers and a lot of slugs, i have considered Sevin as too harsh to use but i do use it on the Hostas for slugs Does Sevin harm bees?

WhiteFly can be detected by lifting the plant leaf and or shaking the plant. You will see adults fly away (white in color) and they are about 2X the size of a gnat. Nothing seems to kill them well. S

Unfortunately Seven will kill good and bad bugs including honey bees.

I noticed yesterday a couple large grasshoppers - maybe a BB gun not really, (maybe a Fly Swatter?)but what a pain! I won't use 7 then, just try to keep things down and irritate them and the White Flies with Neem, Bleach, and Soap. Thankfully(depends on how you look at it) there is not much of a growing season left. Last year we set a record here - no frost till like the day before Veterans Day Nov. 12th..............
