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

Abstract

ABSTRACT: The experiment was conducted 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 treatments included 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. The results revealed that Triazophos 40E.C. 0.04%,was significantely superior over all the botanical treatments 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 in healthy fruits) was registered in untreated control.Highest cost benefit ratio of 1:6. 31 was treatment of Triazophos 40 EC 0.04%. Application of neem oil 1% registered the cost benefit ratio of 1:1.79 and was found most economical.
