Hope that helps!
What is the tiny gray insect with 2 long front legs I saw on a rose bush leaf called ??? Thanks Woodbridge Environmental ! ... now I know it's not a spider mite.
Thanks for the answers, but I'm still hoping for more ideas.
Sounds like you are dealing with a couple of problem bugs. Thrips which are weakening your roses defensive system which allows other bugs like stink bugs to feast. The suggestions from the 1st comment are all good. However, I only use organic practices so I use the hose off methods and insecticidal soaps to control pests. It's really important to keep the area around and under your rose bushes clean, that helps to prevent fungal infections i.e. black spot.
I was told never to hose off the leaves on rose bushes because it will cause fungus to grow. Since I stopped hosing my leaves, the yellow leaves with black spot have stopped ! I live in Florida; maybe in other less humid states it's o.k. to squirt water on the leaves. I don't know !
