Question: how do you get rid of white spots on tomato plants?
Answer: Commercial Spray Sulfur dust is a common treatment for powdery mildew. Mix 1-1/2 to 3 teaspoons of a sulfur dust product with 2 gallons of water, then put some or all of this blended solution into a spray bottle or garden sprayer. Coat the tomato plant evenly, including stems and upper and lower surfaces of the leaves.
