Management of wheat pests under rainfed conditions


Ningaraj S Belagall, Patil RR and Hasansab Nadaf

The studies on “Management of wheat pests under rainfed conditions” were conducted at Dharwad during rabi, 2013. Wheat productivity in Karnataka is very low 988 kg/ha as compared to national average 2900kg/ha. This mainy due to large area (60%) grown under rainfed condition and recent introduction of aphids, wheat shoot fly and stem borer causing (20-35%) reduction in yield. In order to mitigate these pests, organized research programme on bio rational management of wheat pests under field conditions. After six days of treatment Imidacloprid 17.8SL @ 0.3ml/L was found to be best treatment resulted 0.15 aphids per sq. inch per plant per tiller and biorational, Nimbecidine 0.03% @ 5 ml/L recorded 2.33 aphids/sq. inch. Against shoot fly after eight days of treatment. It was significantly lowest percent dead heart (1.03%) recorded at seed treatment with Imidacloprid 600 FS @ 5ml/kg seed followed by foliar spray of Imidacloprid 17.8SL @ 0.3ml/L. Nimbecidine 0.03% @ 5 ml/L recorded (3.48%) dead heart. However, it was (24.83%) dead heart registered at control. Against stem borer Thiamethoxam 70 WS @ 5gm/kg and foliar spray of Thiamethoxam 25 WG @ 0.3 g/L was found to be best treatment that recorded lowest 0.53 percent dead heart after eight days after treatment.
