|The white dots on my dessert rose.
And white powder on my carmellia bush.
I have tried some fungicide and mildew chemical for roses and others but mildew and white powder still return. Please help
They could be insects such as scale or mealybugs or whiteflies. I suggest you take a sample to your County Extension Office and see if they can identify the problem and if necessary prescribe an appropriate remedy.
Their contact info is:
Pinellas County Extension Office, 12520 Ulmerton Road, Largo, FL 33774

Thanks for the question. Please stop in again soon!
