| Abstract/Description: | The commercial formulation Delfin® containing Bacillus thuringiensis var. kurstaki (Btk) serotype 3A, 3B, SA11 (WG) and Margo Econeem™ Plus (EC) based botanical insecticide containing azadirachtin 1% (10,000 ppm) were evaluated alone and in different sublethal combinations against 3rd instars of Spilarctia obliqua Walker (Lepidoptera: Arctiidae) under laboratory conditions. Leaf dip method was used for Btk whereas topical application for azadirachtin. The studies revealed that the LC50 value of azadirachtin after 72 h post-treatment was 0.153% whereas, for Btk it was 0.145%. No synergistic effect was observed when treatment was given at LC20 level of Btk (0.021%) and LC30 level of azadirachtin (0.06%) up to 72 h post-treatment. However, synergistic effect was evident from the combinations at LC25 level of Btk (0.003%) + LC25 level of a zadirachtin (0.004%) and LC30 treatment level of Btk (0.044%) + LC20 level of azadirachtin (0.031%) after 72 h. The studies suggest that combination of botanicals with microbes could be strategized for utilization in integrated management of S. obliqua. |
