Abstract

The experiment conducted to evaluate the efficacy of ten botanical insecticides against rice gall midge, carried out at Rice research farm, B.A.U, Kanke, Ranchi, Jharkhand during kharif, 2016 and kharif, 2017, showed that the crop treated with (Aza.0.03% EC) recorded the lowest incidence of silver shoot (1.76% SS) and proved superior over all the insecticides tested during both the seasons of experimentation. It was followed by rynaxypyr 20 SC (2.54% SS), dinotefuran 20 SG (2.80% SS) and neem baan (Aza.1% EC) (3.14% SS). Similar result were found with the overall pooled mean values. The untreated control plot recorded highest incidence of silver shoot (12.05%). However, all the botanical insecticides remained significantly superior over the untreated crop of rice.
