Title: Extent of suppression of yellow stem borer, Scirpophaga incertulas, Walker population by insecticides in field of scented local Paddy
Abstract: All the treatments were significantly effective in checking stem borer infestation causing to decrease in both dead heart (DH%) and white head (WH%) number. Numerically least damage was noted for imidacloprid 17.8 SL (100 ml/ha), followed by carbofuran 3G (30 kg/ha), fipronil 0.3G (750 ml/ ha), monocrotophos 36 WSC (1125 ml/ha), propenphos 50 EC (500 ml/ha), bifenthrin 10 EC (500 ml/ ha) and chlopyriphos 20EC (1875 ml/ha) in ascending order. The control plot has registered 6.1% DH and 4.3% WH, respectively. In consideration of yield increase over control, maximum yield was registered for imidacloprid 17.8 SL, respectively followed by, carbofuran 3G, fipronil 0.3G and monocrotophos 36 WSC in descending order.
