Effect of Infected Seed and Debris on Chickpea Blight

A study was conducted to determine the effect of blight infected seed and debris of chickpea crop on the initiation and development of Ascochyta blight. It was found that the seed lot with high percentage of infected seeds resulted in early and severe disease development as compared to that with low percentage of infected seed. It was also observed that the diseased debris is more effective than the infected seed for initiation and development of the blight. Similarly, the debris applied at the time of sowing was more effective for blight development than that given at flowering time because exposure of long time.
