Bio-efficacy of newer insecticides against sapota seed borer, Trymalitis margarias Meyrick

KD Bisane, SP Saxena and BM Naik

In the present study, bio-efficacy of newer insecticides against seed borer, Trymalitis margarias Meyrick was tested during three consecutive season of 2012-13, 2013-14 and 2014-15 at sapota orchards of Fruit Research Station, Navsari Agricultural University, Gandevi. The result revealed that profenofos 50 EC 0.075% minimized fruit damage up to 4.03 per cent as well as novaluron 10 EC 0.005% recorded 4.83 per cent fruit infestation put forward superiority over standard check acephate 75 SP 0.1125% (9.86%) and other pesticides. The highest marketable fruit yield of 17.02 and 16.98 t/ha was obtained by the application of profenofos 0.075% and novaluron 0.005%, with less fruit loss of 0.69 and 0.82 t/ha, respectively over other chemicals. While on economics basis, the higher B:C ratio was recorded in novaluron 0.005% (3.28), profenofos 0.075% (3.14) and indoxacarb 0.0036% (2.46). The residue was not detected at harvest of fruits 10 days after spraying of profenofos 0.075% and novaluron 0.005%.
