Abstract

The efficacy of synthetic pesticides (Buprofezin 25 SC 1.25ml/L, Methomyl 40 SP 1g/L, Dichlorvos 76EC 2ml/L and Chlorpyriphos 20 EC 2ml/L) were tested against grape mealy bug, Planococcus maritimus. The results showed that all the pesticides were reduced the mealy bug infestation on grape vines and fruit bunches. The maximum control efficiency was obtained by pesticide Buprofezin 25SC after 1st, 2nd and 3rd spray that was 70.37, 73.64 and 78.65 percent, while Dichlorvos 76EC resulted 60.17, 64.58 and 71.21 percent and Chlorpyriphos 20EC showed s 54.01, 59.06 and 66.84 percent after 1st, 2nd and 3rd spray, whereas Methomyl 40SP reduced 54.03, 59.09 and 66.87 percent infestation respectively. Thus the results indicates that the Buprofezin 25 SC showed a remarkable control on the mealybug colonies on grape vines and fruit bunches.
