Q.Rose Plant Has White Spots
My rose plant is having white spots in it. Give me some solutions.

Well the white spots could be Powdery Mildew and spraying them with a product known as Green Cure is the best remedy for handling it that I know of. It is available on-line at a website called Planet Natural. Powdery mildew will start out with white spots sometimes before it takes over the entire leaf and spreads. If you watch the white spots and they move, it could be mealy bugs and or could be egg sacks from a spider too.
Here are some links to articles of help for you as there are some other things it could be:
