Rice (Oryza sativa L.) stands as a vital staple crop globally, crucial for economic prosperity and ensuring food security. However, its cultivation faces significant threats from pests such as the yellow stem borer, particularly impacting regions like Nepal where rice is a primary crop. In this study conducted in Eastern Nepal, we evaluated the efficacy of six insecticides along with a control group (water spray) using a randomized complete block design (RCBD) replicated thrice. The insecticides tested encompassed Chlorantraniliprole 18.5 SC, Chlorpyriphos 20 EC, Emamectin Benzoate 5 SG, Metarhizium anisopliae-12%, Azadirachtin 0.03%, and Spinosad 45% SC. Our findings revealed that Chlorantraniliprole 18.5 SC applied at a concentration of 0.4 ml/l resulted in the lowest occurrence of dead heart (5.24%) and white ear head (3.21%). Furthermore, this treatment exhibited superior yield and yield attributing traits, indicating its potential as an effective insecticide for mitigating yellow stem borer infestations and fostering rice crop growth and productivity. Although the chemical insecticides demonstrated effectiveness, thorough investigations are required to evaluate their performance on a broader scale and in diverse ecological settings. These studies are essential to validate and apply the results effectively across various agricultural environments.
