Efficacy of certain chemicals with bio-pesticides against Leucinodes orbonalis (Guen.) on brinjal

Abstract

The field trail was conducted at central research field, Department of entomology SHUATS, Prayagraj during Kharif August to November 2019 entitled on “Efficacy of certain chemicals with bio-pesticides against Leucinodes orbonalis (Guen.) on brinjal” The data of lowest per cent of infestation of Brinjal shoot and fruit borer on the mean (3rd,7th, &14th DAS) of first spray revealed that among all the treatments were recorded as follows Flubendiamide (7.15%), Cypermethrin (8.09%) is found to be the next best treatments, Indoxacarb (9.22%), Imidiacloprid (10.55%), Azadirachtin (11.56%), Bt (13.32%), among all the treatments Cartap Hydrochloride (14.57%), is found to be least effective but comparatively superior over the control. Followed by second spray revealed that Flubendiamide (7.47%), Cypermethrin (8.22%), is found to be next best treatments , Indoxacarb (9.31%), Imidiacloprid (10.59%), Azadirachtin (11.04%), Bt (12.70%), among all the treatments and Cartap Hydrochloride (13.81%) is found to be least effective but comparatively superior over the control. In the series of the fruit infestation data on the mean (3rd, 7th & 14th DAS) of the third spray revealed that Flubendiamide (7.47%), Cypermethrin (8.22%), is found to be the next best treatments, Indoxacarb (9.31%), Imidiacloprid (10.59%), Azadirachtin (11.04%), Bt (12.70%), among all the treatments and Cartap Hydrochloride (13.81%) is found to be least effective but comparatively superior over the control.
