To assess the crop losses due to shoot and fruit borer, Leucinodes orbonalis (L.) Guen.in brinjal

Abstract

The present experiment was carried out in Kharif seasons at horticulture farm, S.K.N. College of Agriculture, Jobner during, 2015. The mean fruit yield obtained was 223.48 q ha-1 in plots treated with alternate sprays of acephate (0.05%) and malathion (0.05%), while it was only 115.15 q ha-1 in untreated plots. The yields obtained from protected and unprotected plots differed significantly and the difference in yield was 108.33 q ha-1. The per cent increase in yield over untreated control and avoidable loss were 94.07 and 48.47 Per cent, respectively. If the losses due to L. orbonalis could be avoided by pest control measures, the production can be appreciably increased.
