Effect of seasonal variation on the intensity of market diseases of fruits and vegetables in the district of Birbhum.

Seasonal effects on market diseases of 43 types of fruits and vegetables were recorded from the district of Birbhum, West Bengal, India. Various diseases were found within a fixed period in a year. The percentage incidence of individual pathogens causing different diseases of fruits and vegetables was evaluated. The highest disease incidence was noted in Jun.-Oct. and the lowest in Mar.-May. Each crop carried one dominant pathogen inducing the highest disease incidence. Disease intensity was greatly affected by seasonal variation.
