I got a late start due to a May dry spell. Planted around June 1, followed by 45 days of spraying after every rain(easy lately). I removed the plotsaver two weeks ago. They are definitely getting hammered, but holding up as good as can be expected from a 3/4 acre plot with no agriculture around for a mile in any direction. Notice the new shoots coming in on the plants that have been almost totally eaten.
I have no clue how it will look in September, but I'm optimistic.
