A field experiment on evaluation of spray schedules of different insecticides and botanicals against insect and mite
pests of chilli (Gujarat Chilli–1) was undertaken during kharif 2009–10 at Centre for Research on Seed Spices, Jagudan in a randomized block design with five treatments and four replications. The spray schedule S1 (comprising triazophos 40EC @ 25ml/10 lit., wettable sulphur 50WP @40g/10lit., imidacloprid 17.8SL@ 5ml/10lit., wettable sulphur 50WP @ 40g/10lit and acephate75SP@15g/10lit.of water) registered the lowest population of thrips at three (3.30/leaf) and seven (1.30/leaf) days after spray and, consequently, the lowest leaf curl intensity (2.42, 7.88 and 10.20 per cent at 50, 75 and 100 days after transplanting, respectively). The mean population of mites was also lowest in the spray schedule S1 three (2.19/leaf) and seven days (0.62/leaf) after spray. The damage caused by chilli fruit borer, H. armigera was the least in the spray schedule S1 (2.17%), with the highest fruit yield (2656 kg / ha) of green chilli.
