Integrated Management of Gundhi Bug (leptocorisa Spp.) Infesting Aromatic Rice

The field trial conducted at Rice Research Farm of Birsa Agricultural University, Ranchi during Kharif season of 2018 and 2019 with aromatic rice variety Birsa Vikas Sugandh-1 revealed that three foliar sprayings applied at 25,55 and 85 days after transplanting with tipronu 5SC @ 1200 ml ha-1 recorded lowest mean gundhi bug population (1.96) and highest polled mean yield (47.17 q ha-1) followed by 2.9 and 46.13 q ha-1, respectively recorded with fipronil 5SC @ 1000 ml ha-1. Fipronil @ 1200 ml ha-1 recorded increased grain yield of 29.04 q ha-1 over the control. Alternate spray of fipronil and botanical insecticide neem (2.5 l ha-1) also recorded appreciable reduction in gundhi bug population (4.21) and 23.5 per cent increase in rice grain yield over the control.
