Bioefficacy of Ready Mixture Formulation, Spirotetramat 120 + Imidacloprid 120 - 240 SC against Sucking Pest Complex of Brinjal

Abstract

Field investigations were conducted on brinjal to evaluate the efficacy of ready mix formulation, spirotetramat 120 + imidacloprid 120 - 240 SC against sucking pest complex during 2012 and 2013. The results revealed that spirotetramat 120 + imidacloprid 120 - 240 SC @ 75 + 75 g a.i./ha was found more effective than other treatments in the reduction of the population of jassids (99.21%), whiteflies (99.04%) and red spider mites (91.31%), respectively. The highest marketable fruit yield was recorded in the treatment with spirotetramat 120 + imidacloprid 120 - 240 SC @ 75 + 75 g a.i./ha (72.77 q/ha). The ready mixture formulation, spirotetramat 120 + imidacloprid 120 - 240 SC @ 75 + 75 g a.i./ha proved significantly superior than other treatments and could be utilized as an effective component in the IPM programme of brinjal to manage the sucking pests.
