Abstract:
Field evaluation on efficacy of fipronil 5% SC against early shoot borer (Chilo infuscatellus Snellen) and root borer (Emmalocera depressella Swinhoe) in sugarcane was conducted during 2013. Among the treatments, fipronil 5% SC @ 150 g a.i./ha was found most effective against early shoot borer and root borer where minimum dead hearts (4.29, 3.20 and 2.23%) were recorded after first, second and third spraying, respectively. Fipronil 5% SC @ 100 g a.i./ha was registered the next best treatment in reducing dead hearts after first (4.66%), second (3.74%) and third (2.59%) application followed by fipronil 5% SC @ 90 g a.i./ha (5.05, 3.93 and 2.76%) and fipronil 5% SC @ 75 g a.i./ha (5.18, 4.08 and 3.11%), respectively. Fipronil 5% SC @ 150 g a.i./ha recorded the highest reduction of dead hearts over control (48.75, 65.81 and 78.22%) after three sprays with maximum yield (81.21 t/ha). Thus, fipronil 5% SC @ 150 g a.i./ ha may be useful in the control of early shoot borer and root borer in sugarcane.
