Brown rot and bug hits on peaches
I have 5 peach trees on a farm with corn and beans in nearby fields. The oldest tree (an Elberta) was transplanted 8 years ago, and the youngest has been in ground for 2 years. All but the youngest tree are bearing peaches. I have always sprayed with Bonide Fruit Tree Spray as recommended on the label, and had no problem until the past two years when I lost ALL the fruit on the largest and oldest tree to Brown Rot. The other trees were less severely affected.
This year I sprayed 3 times with Daconil at bud break, full bloom and the last time when the fruit was 1-2 mm in size. Since then I have used the Bonide spray twice at about 2 week intervals.
The fruit is now 15-20 mm in size, and as always there are a lot of bug hits on the fruit manifested by clear gelatinous sap oozing out of the tiny lesions.
I have some Honor Guard for my roses which is 14.3 % propiconazole and not labeled for peaches. Monterey Fungi Fighter (discussed on this forum) is 1.5 % propiconazole with a label rate for peaches of 2 tbs per gallon.
1. Is there any reason I can't use the Honor Guard at 1/2 tsp per gallon?
2. What can I do about the bug hits? The insecticides in the Bonide spray don't seem to be helping.
