Basil Downey
Mildew

A fungal disease that attacks in hot humid months, Basil Downey Mildew often show up in July. Leaves turn yellow and then brown with dark fuzzy spores on the undersides. Image by Sandra Jensen[/caption] This fungus is selective and only attacks basil. There is no effective treatment. Remove infected basil plants and seedlings. Basil Downey Mildew needs a live host so it is fine to compost the diseased plants but do not save seed which may also be infected.  Do not replant with basil until after frost. Prevention is the key. Keep leaves dry by applying irrigation to the soil, not the plant. Space plants to promote air circulation and rapid drying of leaves after rain.

Gardeners

Since 1979 North Carolina Cooperative Extension Master Gardener Volunteers have been guiding homeowners in making environmentally sound decisions in their gardens, lawns and landscapes. Extension Master Gardener volunteers work with NC Cooperative Extension to provide gardeners with unbiased, research based information on gardens, lawns and landscapes. Under the guidance of Extension agents, volunteers complete a 40 hour training program, pass an examination, and complete a 40 hour internship. To remain active in the program volunteers must log a minimum of 20 hours of volunteer service and 12 hours of continuing education each year. Seventy three counties offer the Extension Master Gardener program and there are currently over 4,000 active Extension Master Gardener volunteers.   Go to NCEMGV.org for information on how EMGVs can help you, how you can become and NC EMGV, and how you can support the program.
