apple scab & spots on peaches #194483

Asked June 26, 2014, 11:12 AM EDT

Hi, We're pretty certain we have a case of scab on our grannies. I've read treatment suggestions in the Plant Disease handbook and most, if not all of these, emphasize what to do in the fall to prevent it from coming back. Is there anything we can do now to limit the amount of scab? We're also seeing tiny spots on some of our frost peaches. Any suggestions for this? Thank you! Laurie Powell

For apple scab go to:
http://pnwhandbooks.org/plantdisease/apple-malus-spp-scab

It shows the use of Bonide captan, BSA lime sulfur, or Immunox that can be used right now.

Anything with an O - organic or H - home use should be able to be used in most cases.

Tiny spots on peaches - need to bring a sample into the Lane Extension office, 996 Jefferson and the Master Gardenes can take a look at the problem.  M-Th 10-1 and 2-5.

Probably Corynium blight but we would need to see for sure.
