Abstract:
The field experiment was conducted at Instructional farm of BTC CARS, Bilaspur, (C.G.) during Rabi 2022-23, to know the field efficacy of biopesticides and insecticides combinations against onion thrips. The mean on number of thrips/plant recorded after first and second spray showed that Metarhizium anisopliae 10% (1×10⁸ CFU/ml) + 50% dose of Spinetoram 11.5 SC recorded the lowest thrips (7.91 thrips/plant) was shown to be substantially superior to all other treatments. Metarhizium anisopliae 10% (1×10⁸ CFU/ml) + 50% dose of Imidacloprid 17.8 SL (8.81 thrips/plant) was the second best treatment followed by Spinetoram 11.5 SC (9.43 thrips/plant), Imidacloprid 17.8 SL (9.68 thrips/plant). Whereas, in untreated control (27.23 thrips/plant) were observed.
