Acetamiprid for PC
On another thread, several knowledgable posters said they didn't consider acetamiprid effective for curculio control. I just got the current issue of the IL Extension newsletter, which lists Assail as one of the recommended insecticides to control PC. I believe the reference was primarily directed at apple growers.
I'm wondering if this might be because pyrethroids aren't permitted on apples after petal fall, so a less effective spray is recommended.
My first concern is for my stone fruits, and with as few trees as I have, I prefer not to be mixing up more sprayer-loads than necessary.
