Eco-friendly Pest Management Modules against Sugarcane Borer Complex

Abstract

Results on the evaluation of eco-friendly pest management modules against borer complex of sugarcane are reported. Based on two year data, Module -4 comprising of the application of azadirachtin 0.03 per cent EC @4mLL−1 for sett and soil treatment followed by drenching with chlorantraniliprole 18.5 SC@ 375 mLha−1 at 90 d after planting (DAP), removal of dead hearts at 15 d interval followed by detrashing of dry leaf and propping of cane recorded the lowest mean per cent incidence of root, shoot, top and stem borer (2.88, 3.56, 4.08 and 3.10%, respectively) and proved superior over the rest of the modules. Module-3 comprising of the application of azadirachtin 0.03 per cent EC @4mLL−1 for sett and soil treatment followed by drenching with flubendiamide 480 SC @150 mL ha−1 at 90 DAP, removal of dead heart at 15 d interval followed by detrashing of dry leaf and propping of cane resulted in 3.35, 3.79, 4.30 and 2.93 per cent incidence of the respective borers, and was the next best treatment which was at par with Module -4. The other modules based on per cent pest incidence in the descending order were Module-1>Module-2 >Module-5 >Module-6 > Module 7. The data on combined sugarcane yield revealed that Module -4 recorded the highest yield of 86.83 tha−1 followed by Module -3 (85.15 tha−1). The other management modules arranged on the basis of sugarcane yield followed the descending order Module -2 > Module -1 > Module -5> Module -6 > Module 7.
