Based on above findings, three spray of fipronil @ 1.5 ml/lit. at 15 days interval may be advocated to the onion growers of Nashik (Maharashtra) as an effective strategy for managing thrips in onion during rabi season for increasing the yield of rabi onion. Neem based formulations are seen less effective compared to chemicals for thrips management in onion. Further investigation is required to validate the repeated use of same insecticide at the context of development and impact on the natural enemies. However, fipronil would fit well in the IPM practices as one of the insecticidal components.
