Abstract:

Cotton leaf curl disease (CLCuD) is a potential threat, responsible for low yield in cotton, exclusively transmitted by whitefly (Bemisia tabaci). The investigation was carried out at Cotton Research Station, Sirsa to evaluate progression of CLCuD and whitefly (Bemisia tabaci) in relation to weather parameters. Two Bt-cotton hybrids and two non Bt varieties were sown at three different dates of sowing. Per cent CLCuD incidence increases continuously from appearance to picking. Early sowing found to be more appropriate to minimize CLCuD infestation having less per cent disease incidence and whitefly population as compared to late sown crop. Bt-cotton hybrids are susceptible to CLCuD having higher per cent CLCuD incidence as compare to non-Bt varieties. Correlation analysis reveals that per cent CLCuD incidence and whitefly population shows a significant negative correlation with temperature maximum and minimum while positively correlated with relative humidity morning and evening. Sunshine hours are significant positively correlated with both per cent CLCuD incidence and whitefly population. Whitefly population decreases with increased rainfall and negatively correlated with rainfall. Maximum variability (54.4%) in per cent CLCuD incidence appears due to temperature minimum.
