Efficacy of Botanical Pesticides Against Shoot and Fruit Borer, Leucinodes Orbonalis in Brinjal

The experiment was conducted during summer season of 2003-04 at Vegetable Research Farm of College of Agriculture, JNKVV Jabalpur.The experiment was designed in randomized block design with 7 treatments and 4 replications, to evaluate the performance of some botanical products against the pest complex of brinjal.The treatment include Triazophos 40E.C. 0.04%,Neem oil 1 %,Achook 5 %,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 shoot and fruit damage by Leucinodes orbonalis were recorded and the results were revealed that Triazophos 40E.C. 0.04%,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 treatment of Triazophos 40 EC 0.04% (table 8). Application of neem oil 1% registered the cost benefit ratio of 1:1.79 and found most economical.
