A high··degree of leaf curl disease (LCD) incidence (83%) was observed in the winter crop planted in October as compared to the summer crop planted in February where only 14% incidence of LCD was recorded. Least incidence of the LCD was found in polythene mulch (PM) treatment and in perforated polythene cover (PC) treatment as compared to the other treatments. During the summer crop whitefly population was less at the initial stages of the crop, whereas during the winter crop the whitefly population was very high at the similar stages of the crop. This variation in the whitefly population was due to the differences in temperature and relative humidity. The use of polythene bags to cover tomato plants (PC) and polythene sheets as mulch (PM) were found most effective in reducing the disease incidence and promoting the growth and yield of tomato plants as compared to other treatments.
