Abstract

The experiment was conducted at the Main Rice Research Centre, Navsari Agricultural University, Navsari, Gujarat during kharif 2021, 2022 and 2023 to effectively manage the Scirpophaga incertulas (Walker) infesting rice. The experiment consists of twelve treatments including a combination of seedling root dipping and foliar application. The overall data revealed that all insecticidal treatments significantly reduced the incidence of YSB (dead hearts and white ears) than the untreated control. Treatment Thiamethoxam 25 WG (root dipping) + Chlorantraniliprole 0.40 GR (field application) was found most effective (5.79 % dead heart and 12.23 % white earhead) followed by treatment Thiamethoxam 25 WG (root dipping) + Flubendiamide 0.70 GR (field application) (9.05 % dead heart and 13.34 % white earhead) in terms of management of yellow stem borer of rice and also registered highest yield of rice seed 5.23 and 5.10 t/ha, respectively. Furthermore, the seedling root dip in the insecticidal solution absorbs a good amount of insecticide which is translocated in the plant and controls the yellow stem borer damage. The same treatments also show the below quantification level residues at the time of harvest; thus, this is the safe practice with respect to the environment and health.
