Evaluation of Management Modules Against <i>Scirpophaga excerptalis</i> Walker in Sugarcane

An experiment on the evaluation of management modules against sugarcane top borer Scirpophaga excerptalis was conducted from 2019-20 to 2021-22 at the Pusa Farm, SRI, Pusa. Data on incidence and yield in different modules (M1, M2, M3, M4, M5 and M6) reveals that all modules are significantly superior though they varied in their efficacies at 120 DAP and 180 DAP, respectively. Among these modules, M22 (Comprised of RDF, removal of deadhearts, collection and destruction of egg masses followed by drenching with chlorantraniliprole 0.4 G @ 25 kg/ ha after 90 DAP) recorded least incidence (5.23%) followed by M6 after 120 and 180 DAP. The module M4 gave maximum yield (86.52 t/ ha) and generated the highest net income of 0.65 lakhs and BC ratio of 0.32.
