@thecityman I got a chance to look at my trees closer. My large Elberta with the most fruit seems to be decimated. Every fruit has a puncture mark or crescent scar. My early peaches which were larger - Desiree, Reliance and Red Haven seemed to have faired better. I read somewhere that PC leave the fruit alone after the pit has formed, not sure if that is correct.
Next year I am definitely doing a portion of my peaches with bags. I meant to do it this year but ran out of time.
This is my first year of using Imidan, so I cannot speak to the kickback, I have seen University charts that indicate it is curative.
What I would really like to understand is what I did wrong spraying. On Sunday before I left I sprayed my large Elberta drenching it with Imidan/Captan. My orher trees had been sprayed two to three days prior. I used Sticker, Spreader, PH Balancer to get it to the water to the right PH level. What do commercial orchards do when it rains 3 or 4 days in a row to keep the insecticide effective?
