Sweet cherry orchard. With all this rain, What should be the minimum spray interval to keep leaf spot at bay? We have 1 block that has infection and 2 others that have not. We also are combating an abandoned orchard close by that does not get treated. We dont want to spray too much or too little, but the rain every other day makes it hard to judge. Any inside would be greatly appreciated.

If it rains a lot, more than an inch, you have to get back in and spray again immediately. Otherwise, a 7-10 day schedule will work for sweet cherry. Tart cherry is more susceptible to leaf spot, and I would go every seven days there.
Good luck.
