NEW PROMISING INSECTICIDES FOR THE MANAGEMENT OF BRINJAL SHOOT AND FRUIT BORER, Leucinodes orbonalis Guenee
Two new insecticides, viz., rynaxypyr 20% SC and flubendiamide 480 SC were evaluated in the field against brinjal shoot and fruit borer, Leucinodes orbonalis Guen. during winter, 2007 and summer, 2008 at the Central Research Station farm, Orissa University of Agriculture and Technology, Bhubaneshwar with brinjal cv. "Utkal Anushree". Four foliar spray applications of the chemicals were given at 11 days intervals starting from fruit initiation. The results revealed that rynaxypyr 20% SC @ 40 and 50g a.i.lha gave 95-97% reduction in the 'shoot damage and 87-90% reduction in-fruit damage on number basis and 88-90% on weight basis at ten days after fourth spray, compared to untreated control. Both the new compounds were safe to natural enemies at 0, 3, 7 and 10 days after spraying. The healthy fruit yield recorded was significantly highest in plots treated with rynaxypyr 20%SC @ 40 and 50g a.i.lha during both the seasons of field testing.
