Abstract:
A field experiment was conducted in the year 2018 at University Experimental Farm, ‘C’ Unit, BCKV, Kalyani, Nadia, West Bengal to evaluate insecticide molecules against yellow stem borer, Leaf folder and hopper pest in rice variety “Satabdi/Minikate” comprising seven treatments including control and three replication in randomized block design during summer 2018. The experimental data revealed that the least leaf folder population i.e. 0.00 and 0.33 was recorded in the treatments Acephate 95% SG@ 562.5 g a.i./ha followed by Acephate 95% SG@ 500 g a.i./ha. (100 and 95.87% reduction over control) and were on par with other, least percentage of dead hearts 0.55% and 0.91% was recorded in the treatments Acephate 95% SG @ 562.5 g a.i./ha followed by Acephate 95% SG @ 500 g a.i./ha. (94.78% and 91.30% reduction over control). The yield data of Grain Rice was highest 33.50 and 32.50 q/ha Acephate 95% SG@ 562.5 g a.i./ha and Acephate 95% SG@ 500 g a.i./ha.
