Last year was the first year that I had a peach crop that I really watched and had extensive PC damage. This year I have been watching much closer and was ready.
I intentionally did not spray all of my peach trees this year with Imidan before PC hit. I wanted to see when PC hit (it was today/last night) and better understand the enemy. Looking at my trees it looks like PC only hit the larger peaches (maybe nickel size?), the smaller peaches were not bothered. Is that because the peach needs to be nickel size or larger for the PC to enter or had the PC just not gotten to the smaller peaches?
For the most part the trees I sprayed with Imidan were not damaged by PC, with one or two peaches being the exception. Imidan is supposed to be curative, does anyone know how curative it is on peaches if sprayed within one to two days of larva infection (percent of loss)?
Also some of the larva entry points look like a scar with some being a round tunnel (no scar). Do i have two different insects attacking my peaches at the same time or does sometimes PC not leave a scar?
