I know about strong chemicals. I’ve tried to find other approaches to protect my various fruits. This post may be for those who are like-minded.
I am in central MA where humidity is a problem. I have Oriental fruit moth, plum curculio, coddling moth, stinkbugs, apple maggot flies, etc damaging fruit. Brown rot has been an issue, too.
One of the approach I have used for the past 3-4 years on stone fruit ( more years on apples) is bagging.
Apples and pears - Plastic ziplock bags. This is the first year I have seen sunburn spots on some apples, russetting in pears, excessive moisture trapped in most bags. I removed all the bags from pears since they mostly can fend for themselves. I removed some bags from apples that show sunburn stress.
Peaches, plums- I have tried three kinds of bags.
Clemson paper bags: needs refinement of putting them on efficiently. Jury still out regarding if ripe fruit will rot or not. Several bags flew off the trees. Bags that had tears or not applied tightly, had bugs damaging fruit inside.
Organza bags: so easy to put on. If bags touch the fruit. The fruit are doomed. Bugs lay eggs through the bags.
Customized perforated bread bags: easier than Clemson bags to apply. Can apply on a whole branch. Bug damage- same as organza bags.
In addition to pests, brown rot is a serious issue on stone fruit where I am. With bags on, it is not possible to spray effectively against brown rot. Spraying through the bags, so far, get a poor result.
At this point, I may abandon bagging. Stick with Surround, Spinosad, sulfur, and a few sprays of Indar. At least, if any fruit survive bugs, I don’t have to worry about rot.
