Features
- Called 'downy' because of the soft, fuzzy white or grey growth on the underside of leaves. Also known as water molds because they thrive in wet conditions
- Appears as fuzzy white, grey, or purple growth on the underside of leaves. The top surface shows yellow or brown angular spots between leaf veins
- Affects leaves primarily. The organism penetrates leaf tissue and feeds on plant cells from within
- Leaves develop yellow or brown angular spots on top surface. Underside shows whitish, greyish, or purplish fuzzy growth. Leaves eventually turn brown and die
- Obligate parasites that need live plants to survive and multiply. Produce spores that spread through air and water splash. Can overwinter in plant debris
- Individual spores are microscopic, measuring 10-30 microns. The fuzzy growth visible on leaves consists of thousands of spore-producing structures
- Thrive in cool, moist, and humid conditions. Spread rapidly when leaves stay wet for extended periods. Most active in temperatures between 15-20°C (59-68°F)
- Affects many plants including rose, impatiens, sunflower, melons, cucumbers, lettuce, spinach, grapes, onions, and basil
- Prevent by watering at soil level to keep leaves dry, ensuring good air circulation, avoiding overhead watering, and removing infected plant debris. Space plants properly
- Treat with neem oil, baking soda solution, or copper-based fungicides. Remove and destroy infected leaves. Apply treatments early in the morning
