A field experiment was conducted for two consecutive years in rabi on onion variety Agrifound Light Red. The result showed that over all lowest mean thrips population (5.37 nymphs/plant) were recorded in spray of Fipronil @ 1.0 ml/L + silica based surfactant as well as highest gross yield (342.24 q/ha) and marketable yield (326.99 q/ha). The B:C ratio (9.11:1) was also recorded in the same treatment. The efficacy of insecticides was increased by addition of silica based surfactant and minimizing thrips population as well as increased the yield of onion bulbs.
