Abstract

With the widespread adoption of high yielding rice (Oryza sativa L.) varieties and accompanying changes in the cultural practices, rice leaf folder [Cnaphalocrocis medinalis (Guenee)] and yellow stem borer [Scirpophaga incertulas (Walker)] has attained the status of major pests and influence the yield if proper timely management practices are not adopted. For effective management of these pests, identification of new molecules with novel mode of action, low toxicity to non-target insects and environmental safety is required for sustainable IPM. Chlorantraniliprole 0.4% gr (Ferterra 0.4% gr) is an anthranillic diamide insecticide in granular form for the control of lepidopterous pests in rice. A field experiment was conducted to evaluate the efficacy of chlorantraniliprole 0.4% gr (Ferterra 0.4% gr) against rice leaf folder and yellow stem borer during rainy (kharif) seasons 2017–19. The study revealed that broadcast application of chlorantraniliprole 0.4% gr @40 g a.i./ha at tillering stage was found effective and best insecticidal treatment in reducing rice leaf folder and yellow stem borer infestation with no phytotoxicity symptoms and increased grain yield. Chlorantraniliprole 0.4% gr @40 g a.i./ha was also safer to the natural enemies of the rice ecosystem. Post-harvest residual analysis of chlorantraniliprole 0.4% gr was found below the limit of quantification, i.e. 0.01 ppm in rice grains, soil, paddy straw and husk at recommended and double of the recommended dose indicating its safety to human, animals and environment.
