Evaluation of bio-pesticides and indoxacarb against gram pod borer on chickpea

Abstract

An experiment conducted during rabi, 2015-16 to evaluate the efficacy of bio-pesticides and indoxacarb against gram pod borer on chickpea from six treatments viz., Indoxacarb, Bacillus thuringiensis, Nuclear Polyhedrosis Virus, NSKE, Azadirachtin and Garlic extract. The indoxacarb 14.5 SC (1.0 ml/lit.) was found most effective in crop protection. NSKE (5.0 ml/ha), azadirachtin 0.3 EC (5.0 ml/lit.), HaNPV (250 LE/ha) and B. thuringiensis (1000 ml/ha) were found moderately effective in reducing pod borer population, while garlic extract (10 ml/lit.) was found least effective. The minimum pod damage (4.69%) was recorded in treatment of indoxacarb followed by NSKE (10.41%) and azadirachtin (10.84%). The maximum pod damage (14.27%) was found in garlic extract treatment, while it was 20.95% in control. The maximum seed yield was obtained in the treatment of indoxacarb 14.5 SC (16.49 q/ha) whereas it was minimum in garlic extract (10.10 q/ha) treatment. Maximum B:C ratio was obtained in the treatment indoxacarb (9.52), while minimum in garlic extract (0.17).
