Abstract

During the kharif season, green gram is a crucial pulse crop. However, arthropod pests, especially jassids and whiteflies, which also serve as yellow mosaic virus vectors, severely limit its yield. Biodynamic formulations and other sustainable pest management strategies are becoming increasingly popular since they are safe for beneficial insects and environment. A field study was carried out on management of arthropods on green gram with biodynamics at Jabalpur, Madhya Pradesh, during the 2022–23 kharif season. Nine treatments, including an untreated control and three replications, were included in the randomised block design experiment. Two concentrations of biodynamic formulations, including Brahmastra, Agniastra, Neemastra and Dasparni Ark, were used. Crop yield, economics, safety to natural enemies, yellow mosaic virus incidence and pest populations all were observed. The result revealed that the most successful treatment was Brahmastra at 45 mL/L, which significantly reduced the infection of yellow mosaic virus as well as the populations of whiteflies and jassids. Brahmastra at 30 mL/L, Agniastra at 45 mL/L, Agniastra at 30 mL/L, Neemastra at 45 mL/L and Neemastra at 30 mL/L followed this treatment, which also produced the best seed production and economic benefits. In comparison, Dasparni Ark at 30 mL/L treatments were less successful. Additionally, it was discovered that all biodynamic treatments were safe for natural enemies. The study showed that biodynamic formulations, especially Brahmastra at 45 mL/L, provide a cost-effective, environmentally safe and efficient way to control whitefly and jassids in green gram. Adoption of these formulations can promote integrated pest control techniques and sustainable crop production, particularly for farmers looking for affordable and environmentally suitable substitutes.
