Abstract
Field studies on evaluation of biopesticides against jassid, Amrasca biguttula biguttula (Ishida) in okra crop was carried out at the experimental area of Habib Farm, District Hyderabad, during the year 2012. The crop was sown on well preapred seedbed keeping 45 cm distance between ridge to ridge, after thinning a plant to plant distance of 22.5 cm in CRB design. During the present study four replications and five treatments i.e. T1 (Neem Powder), T2 (Tobacco leaves), T3 (Neem Oil), T4 (Neem oil + Beneficial micro-organism B.M), T5 (Control) were used. The pre-treatment observations were taken 24 hours before spray whereas post-treatment observations were taken at the intervals of 24, 48 and 72 hours and after one and two weeks. Relative neem oil + BM displayed greater reduction of jassid population (78.47%), followed by neem oil (76.57%), whereas, neem powder (65.46%) and tabacco leaves (63.16%) were less effective in reducing the population of jassid in field. However, during 2nd and 3rd spray the efficacy of all products remained the same altough it was higher as compared to 1st spray. The average performance of three sprays was maximum in case of (Neem oil + B.M ) (81.28%), followed by neem oil (79.40%), neem powder (72.93%) and tabacco leaves (69.00%) respectively. The present study strongly suggests that the use of bio-pesticides may be helpfull to reduce the effect of pesticides in the environment.
