Basil Downy Mildew Reported in Haywood County – July 23, 2018

— Written By

Basil downy mildew (BDM) has been observed in our sentinel plots at the Mountain Research Station in Waynesville. Symptoms first appeared on 7/16/18 and about 10% of the plants were affected.

Growers are advised to actively scout for the disease and implement management strategies to prevent pathogen spread. For more information regarding identification of the pathogen and management of the disease please refer to our basil downy mildew fact sheet. Sweet basil varieties resistant to downy mildew are now available and listed in the fact sheet.

BDM has already been reported in NC, but had not been reported in western North Carolina yet this year.

If you think you have downy mildew in your basil please contact your local Extension Agent and send photos and/or physical samples to the Plant Disease and Insect Clinic so we can assist you with diagnosis of the disease.
