AnthracnoseCaused by: Colletotrichum higginsianum
Problem Category: Fungal Disease
Symptoms: Small circular or irregularly shaped dry spots which are gray to straw in color on leaves; a high number of spots may cause the leaf to die; lesions may coalesce to form large necrotic patches causing leaves to turn yellow and wilt; lesions may split or crack in dry centers.
Comments: Fungus overwinters on leaf debris and on related weeds; disease emergence is favored by moist, warm conditions.
Management: Control of disease depends on sanitary practices; treat seeds with hot water prior to planting; rotate crops; plant in an area with good soil drainage; remove all cruciferous weeds which may act as a reservoir for the fungus.
Control: Spray 10% cow urine or 6ml Fermented Buttermilk to control the Anthracnose
