Abstract:
Damage to rice crop by insect pest has been one major problems in rice cultivation. The present study focuses on the management of major rice pests like yellow stem borer and leaf folder by seed treatment of rice seeds with Tetraniliprole 480 FS by both dry seed treatment method and wet seed treatment method. The results indicated that both the seed treatment methods @ 3.6 g a.i. / kg seeds was the best treatment for the management of both the insects. Moreover, no side effects on the germination of seeds were recorded in the present study. The efficacy of Tetraniliprole 480 FS on the natural enemies was negligible where maximum parasitization (20.21 percent in 2016 and 23.47 percent in 2017 after 40 DAT) and spiders (1.98 spiders/m² in 2016 and 2.92 spiders/m² in 2017 after 40 DAT) were recorded on rice seedlings treated with Tetraniliprole 480 FS 3.6 g a.i. / kg seeds. The maximum yield (53.89 q/ha) was reported in rice treated with Tetraniliprole 480 FS 6 g a.i. / kg seeds.
