Summary
An experiment was conducted in summer 2010 to determine the role of weather parameters on the epidemiology of Mungbean yellow mosaic virus (MYMV) in mung bean in south Gujarat, India. Gradually, the disease increased in the field and covered 82.39% of the area during the 22nd standard meteorological week (SMW) when the plants were ~93 days old. The rate of increase of the disease was maximum during the 15-17 SMW, subsequently, it decreased. There were 2 different peaks of increase in the whitefly (Bemisia tabaci) population, i.e. from the 10th to the 12th SMW and from the 16th to the 17th SMW when the crop was 52-58 days old. Afterwards, the whitefly population decreased during the 18th SMW, slightly increased again during the 19th SMW and further decreased rapidly. Initially, the maximum temperature remained in the range of 33.3 to 33.6 degrees C during the 9th and 10th SMW, which was found congenial for the population buildup of the whiteflies. The maximum temperature during the 17th SMW increased rapidly and reached 38 degrees C, subsequently, decreased to 35.6 degrees C during the 18th SMW and further increased to 39 degrees C during the 19th SMW. MYMV incidence was positively correlated with afternoon humidity, average humidity, minimum temperature and average temperature. The pattern of increase in the disease incidence was almost similar to the whitefly population. The whitefly population had direct positive correlation with the disease incidence.
