I would like to spray my peach trees preventatively with Mycoshield.
The trees became infected in early summer here in 6b/7a sprays every
two weeks solved the problem but not completely. No signs of infection
as of yet, but should I begin spraying now?
Not sure what you’re spraying for? I have been spraying mine for well over a month, 3 sprays in in zone 5b.
Sorry, Bacterial Spot
