Peach/Nectarine leaf drop
Every June, the leaves on my dwarf peach and nectarine trees turn a light tan and drop off. There are webs surrounding the leaves. I have been told that I may have mites. I have sprayed Volck Oil during the dormant season and sprayed with Malathion after I notice the damage starting. This has not been effective. Any ideas? I'd appreciate any help I can get.
Have you tried a systemic remedy in addition to topicals? Bayer makes a good product: Bayer Advanced Tree & Shrub Insect Control Concentrate This works from the inside out and lasts for an entire year. Good luck!
