Efficacy of insecticides against sugarcane leaf hopper (Pyrilla perpusilla Walker) under field conditions and their effect on yield

Abstract

The maximum pest reduction was found with dinotefuron. Pymetrozine and diafenthiuron also showed good insecticidal control. The yield was highest in dinotefuron 20% SG (90.89 t/ha), followed by imidacloprid 17.8% SL (84.76 t/ha), pymetrozine 50% WG (82.89 t/ha), diafenthiuron 50% WP (81.42 t/ha), thiamethoxam 25% WG (80.84 t/ha), fipronil 5% SC (80.84 t/ha) and acetamiprid 20% SP (77.52 t/ha). The untreated control recorded 70.21 t/ha yield. © 2019 MPH.
