ECOFRIENDLY MANAGEMENT OF BRINJAI SHOOT AND FRUIT BORER BY SOME CHEMICAL AND BOTANICAL INSECTICIDES AND THEIR IMPACT ON NATURAL ENEMIES

Abstract

A field experiuieiit \%as condttcted in the experimental thrni of Sher-e-Banida Agricultural iii \crsit - Dhiaka during November. 2012 to Ma - 2013 to e aluate seine hotaiticals and chemical insecticides and hand picking and destruction of infsted shoots and fruits and their impact on natural enemies lhr ceo-f nendlv manauenient 01 brinjal shoot and fruit borer (USER). Leuciiunlev 0/IJUIUF/is (luenee. Eight treatments were used at 7 days interval. Results presented the lowest shoot (6.90%) and fruit inlestation (13h7%) and lowest plant infestation (19.71%) and maximum fruit length and girth. number of fruit per plant (16.08) and highest fruit yield (23.95 I/ha) were achieved by Ripeord 101iC 111 mI/I, of water compared to all other treatments.

Ripcord I OEC adversely afiècted and reduced the highest population of ladybird beetle adult (87.43%) and lan'ae (87.710/u): and field spider (88.12%) over control as counted visually. Suntap 5OSP also showed the higher adverse effects on the natural enemies, whereas hand picking and destruction of infested shoots and fruits performed the least hazardous treatment ladybird beetle adult and larvae as well as field spider and oilier arthropods. iliough. Ripeord and Suntap reduced the highest level of RSFI3 infestation, but they were mostly harniRil to the atrthropod hiodiversity in the brinjal ecosystem by reducing the maximum level of the natural enemy populatum than other 1,otanicals and cultural control which were comparatively sale in ceo-friendly management of brinjal shoot and fruit borer.
