Abstract
A field experiment was carried out at the field of Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur during the 2022-23 Kharif season to investigate the dynamics of Bemisia tabaci and YMD incidence on the soybean crop variety JS-335 with weather parameter. Incidence of YMD howed a negative but non-significant relationship with the highest temperature and negatively significant correlation (-0.627*) with the lowest temperature. There was a non-significant positive correlation between the disease and the lowest relative humidity as well as rainfall. In terms of Whitefly population, there was a significant negative correlation (-0.752**) with rainfall, indicating that as rainfall increased, Whitefly population decreased.
