Abstract
Brown planthopper, Nilaparvata lugens StÃ¥l is a dominant species among the noxious rice pests and causes considerable damage in India. Various strategies have been employed to manage brown planthopper and insecticides factor as the frontline defense. However, it has now become difficult to manage brown planthopper with the present genre' of insecticides due to the development of resistance. Identification of new molecules with selective properties, a novel mode of action, low toxicity to non-targets and environmental safety becomes a newer tool for the sustainable management of brown planthopper. In this direction, dinotefuran 20 SG a new molecule was evaluated under field conditions to access its efficacy against brown planthopper in basmati rice during Kharif, 2019. Results of the present investigations indicated that dinotefuran 20 SG at 40 g a.i./ha as a spray (when pest crosses ETL) was the effective treatment in the reduction of brown plant hopper population. The added advantages included non phytotoxicity of foliar application of dinotefuran 20 SG @ 40 g a.i. ha-1 to the paddy crop. Mean grain yield (38.1 q ha-1) was recorded in dinotefuran 20 SG sprayed plots as compared to control (32.3 q ha-1) and increase in grain yield over control was recorded to be 15.5 per cent.Â
