Abstract:
In the present investigation the seasonal occurrence and effectiveness of seven insecticides on Brinjal shoot and fruit borer were evaluated during
Kharif 2015 in Central Research Farm, SHUATS, Allahabad. The occurrence of shoot and fruit borer commenced from 34
rd standard week (August fourth week) on shoot with an average population of 0.64% infestation. Infestation on fruit starts in 37
th standard week (September second week) with an average population of 3.31% infestation. The shoot and fruit borer population increased and gradually reached its peak level of infestation 5.71% at 41
st standard week (October second week). The population of shoot and fruit borer decreased with infestation of 2.26 % at 45
th standard week (November 1
st week) there after declined trend was observed as temperature decreased. The shoot and fruit borer population increased with increasing temperature and positively correlated with maximum temperature. Minimum percent of shoot infestation, percent fruit infestation and B: C ratio were observed in spinosad 45 SC with (7.49%, 10.12% and 1:6.08) respectively.
