A novel study on efficacy of animal urine against Helicoverpa armigera (Hubner) on chickpea at Pantnagar, Uttarakhand

Abstract

A novel and preliminary field study was conducted on the efficacy of animal urine against gram pod borer, H. armigera (Hubner) on chickpea at experimental farm NEBCRC, GBPUA&T Pantnagar, Uttarakhand during rabi crop seasons of 2016-17 and 17-18. The pooled data for both the years clearly showed that all the treatments were found significantly superior over control. The data on mean larval population, pod damage and grain yield was obtained for Indoxacarb (14.5 SC) @ 0.9ml/l (3.34larvae/plant, 11.38% and 15.15q/ha) showed that the chemical was performed the best among the treatments followed by Desi cow urine (4.50larvae/plant, 13.00%, 12.92q/ha), Horse urine(4.33 larvae /plant), 13.97%, 12.55q/ha) and Goat urine (5.83larvae/plant,15.65%,12.25q/ha) in comparison to untreated control (19.34larvae/plant, 38.70%, 5.51q/ha). On the other hand, the mean population of pupae of parasitoid, Campoletis chloridae was recorded the least (0.78/plant) in Indoxacarb and significantly more per plant (2.42.2.42 and 2.00) in Desi cow urine, Horse urine and Goat urine treated plots, respectively. Thus, the present novel study clearly revealed that animal urine can safely and effectively be incorporated in integrated pest management schedule against Helicoverpa armigera on chickpea.
