The experiment was conducted in randomized block design with 7 treatments and 4 replications, to evaluate the performance of some botanical products against the sucking pest of brinjal. The treatment included Triazophos 40E.C. 0.04%, Neem oil 1et al, Achook 5et al,NSKE 5%, Karanj oil 1%,Eucalyptus oil 1% and an untreated control. Four spraying of each treatment were conducted starting 30 days after transplanting, at an interval of 15 days. Observation on population of suking pests (aphids and jassids) were recorded before treatment and 3,7and 10 days after each sprying. The results revealed that Triazophos 40E.C. 0.04% was significantely superior over all the botanical treatments. did not significantly shoot damage in different treatments ranged between 3.9 to 10.1%.Highest healthy fruits yield (24.76q/ha) was recorded in the treatment of Triazophos 40E.C. 0.04% followed by the treatment of neem oil 1% (20.54 q/ha healthy fruits), and both the treatments were statistically at par Yields in remaining treatments were at par and ranged between 19.57 and 15.23 q/ha. Lowest yield (10.50 q/ha healthy fruits) was registered in untreated control. Highest cost benefit ratio of 1:6. 31 was in treatment of Triazophos 40 EC 0.04%. Application of neem oil 1% registered the cost benefit ratio of 1:1.79 and found was most economical.
