Roses Loosing Leaves

Help. I have a Rose bed of 50 floribundas. It has been raining here in North Jersey almost every day in June. I use Bauer All-in-One to control insects aand disease, but that did not seem to stop whatever my roses have. I am thinking it is an insect. The leaves start off with a bronze color or yellow with black spot. When I turn over the leaves, I see lots of movement by mircoscopic bugs (mites?) Eventually, the leaves turn brown, dry up, and fall off.


I have sprayed with Malathion and dusted with Rosex, yet my plants now have lost 50% of their leaves. I will continue to spray and dust, but I am now considering adding some Rose-tone fertilizer to help re-energize. Thoughts on any of this? I am afraid that all the plants will just defoliate and die. The new growth does appear healthy though, on last check.

Not a bad site but give this one a peek the site manager is more organic and a lot more informative

and will really teach you a lot for your current problem as well other problems I hear you on the rain there same here in Mass. I went out on day two of four of them rains in a late day down pour with a spray bottle of neem and the water ran right off the leaves.

Leaf watering is by far the worst thing for leaves ( as well a garden hose) either way Neem is more pest control but as it is an oil it can burn leaves I only use it when the temperature is at 60 to 65 and will stay there for at least a day
