Abstract:
In present investigation on seasonal incidence and efficacy of some insecticides against shoot and fruit borer on Brinjal in cultivar Banarshi round was conducted during kharif season 2015 in Central Research Farm, SHUATS, Naini, Prayagraj (Allahabad). The occurrence of shoot and fruit borer commenced from 34rd standard week (August fourth week) on shoot with an average population of 0.87% infestation. Infestation on fruit starts in 38th standard week (September third week) with an average population 4.31% infestation. The shoot and fruit borer infestation increased and gradually reached its peak level of infestation 6.21% in 41st standard week (October second week) and there after declined trend was observed as temperature decreased. Shoot and fruit borer population increased with increasing maximum temperature and positively correlated with maximum temperature. Three application of seven insecticides viz; Emamectin benzoate 5SG (0.3g/lt), Spinosad 45 SC (0.22ml/lt), Cypermethrin 10 EC (2ml/lt), Acephate 75SP (0.5g/lt), Indoxacarb 14.5 EC (0.34ml/lt), Lambda chyalothrin 5EC (0.27ml/lt) and Delfin 5WP (0.3g/lt) were evaluated against shoot and fruit borer. Minimum percent of shoot infestation, percent fruit infestation and B:C ratio were observed in Emamectin benzoate with (6.67%, 7.02% and 1:5.67) respectively. Which are followed by Spinosad (9.71%, 8.58% and 1:5.34)
