Management of Sapota Seed Borer (Trymalitis margarias Meyrick) with some Newer Pesticides

Profenophos 0.075 per cent @ 1.5 mL L⁻¹ minimized fruit damage up to 3.95 and 3.67 per cent after three sprays against seed borer, Trymalitis margarias Meyrick at Gandevi, Gujarat and Palghar, Maharashtra respectively, and showed superiority over the standard check acephate 0.1125 per cent and other pesticides. It showed comparable results with novaluron 0.005 per cent @ 0.5 mL L⁻¹ at Gandevi (4.41%) and indoxacarb 0.0036 per cent (4.63%) and novaluron 0.005 per cent (4.94%) at Palghar. However, the highest marketable fruit yield of 14.94 t ha⁻¹ was obtained from the trees sprayed with novaluron 0.005 per cent which was statistically on-par with profenophos 0.075 per cent (14.89 t ha⁻¹) and indoxacarb 0.0036% (13.42 t ha⁻¹) at Gandevi, whereas profenophos 0.075 per cent produced a higher marketable yield of 17.09 t ha⁻¹, followed by indoxacarb 0.0036 per cent (16.53 t ha⁻¹) and novaluron 0.005 per cent (15.76 t ha⁻¹) at Palghar. No residues were detected on fruits harvested 10 d after spraying of profenophos 0.075 and novaluron 0.005 per cent.
