Ascochyta blight

Caused by: Ascochyta rabiei
Problem Category: Fungal Disease
Symptoms: Water-soaked pale spots on young leaves which enlarge rapidly under cool, wet conditions and coalesce to cause blighting of leaves; elongated lesions often cause girdling of the stems which break off; new shoots may form at the breakage points; if pods become infected it can lead to reduced seed set; if infected seeds are planted, the seedlings will develop dark brown lesions at the base of the stem and may dry up and die
Comments: Disease emergence if favored by wet weather; spores are carried to new plants by wind and water splash
Management: Grow more resistant varieties such as PBA Slasher or Genesis™ 090; even resistant varieties require fungicide application at early podding to ensure high quality seed; more susceptible varieties may require a first fungicide application approximately 4-6 weeks after sowing
Control: spray 2 times 10% Cowdung+Asafoetida solution in 10 days interval to control blight
