Abstract

The present experiment was conducted with the objective to find out the effect of different insecticides for the control of thrips in the onion crop. The result show that overall average lowest thrips population (7.31 nymphs/plant) as were recorded in T2 treatment (1st spray Imidacloprid @ 0.5 ml/L + Copper oxychloride @ 3.0 g/L, 2nd spray Lambdacyhalothrin @ 1.0 ml/L + Carbendazim @ 2.0 g/L, 3rd spray Fipronil @ 1.0 ml/L + Carbendazim @ 2.0 g/L, 4th spray Profenophos @ 2.0 ml/L + Carbendazim @ 2.0 g/L,5th spray Spinosad @ 0.3 ml/L + Copper oxychloride @ 3.0 g/L) and highest gross and marketable yield (336.64 q/ha and 328.85 q/ha) were also recorded in same treatment applying four sequential sprays to keep control thrips population and diseases .The highest ICBR (1:6.69) was also recorded in the treatment (T2).The highest thrips population as well as the lowest yield was recorded in the control treatment.
