Do not over-fertilize vegetable crops with nitrogen. Control Remove affected leaves if practical. Use sulfur as directed. Or try a quick homemade spray made with baking soda . Use a drip-watering system instead of a regular sprinkler.
Sprinklers splash water from the ground and from affected plants and help spread the mildew.
Generally noticed on lawns. Moles tunnel under turf hunting earthworms and grubs. Prevention Nothing prevents a determined mole. However, they do not readily invade very wet or very dry soils. The only reliable control is a properly installed mole trap.
