Seasonal incidence and efficacy of certain low risk insecticides against Leucinodes orbonalis on brinjal

Omprakash S and Raju SVS

A field trial was conducted to study the seasonal incidence and efficacy of certain novel insecticide molecules alone and in combination against Leucinodes orbonalis. Initial incidence of L. orbonalis was observed during the first week of October and peak incidence was recorded during the last week of October 2011. The incidence of L. orbonalis had non-significant relation with abiotic factors like maximum, minimum temperatures and morning relative humidity, but significant negative relationship with rainfall, positive correlation with coccinellid beetles as well as spiders was observed. Regarding the field treatments, among the 10 treatments, Spinosad showed significantly higher efficacy followed by Triazophos, while combination treatments showed moderate efficacy in reducing shoot and fruit damage caused by L. orbonalis and helped in increasing yield of brinjal.
