Abstract

During Kharif, 2020 a survey was conducted by using multistage random sampling technique for recording disease incidence of yellow mosaic disease of mungbean in three districts of Haryana viz., Hisar, Sirsa and Fatehabad. It was found that the highest mean disease incidence was recorded from village in Sirsa and least from location in Hisar district. Yellow mosaic disease produces the symptoms like small yellow specks, mosaic, chlorosis, stunting of plant, puckering of leaves, short flower stalks bearing few flowers and yellow pods with immature and shrivelled seeds. As the disease survey helps in estimating the losses caused by the disease. The disease incidence and whitefly population were recorded simultaneously from mungbean field to calculate the correlation as well as regression equation. Where the whitefly population was found to be positive and significantly correlated with disease incidence at 5% level of significance. The various weather parameters like temperature, rainfall,
