Abstract
Blackgram (Vigna mungo) is a significant pulse crop grown in India, recognized for its nutritional value and contribution to soil fertility through nitrogen fixation. A major constraint to blackgram productivity is weed infestation, which can cause substantial yield reductions. Traditional weed control methods, such as manual weeding, are often labour-intensive, time-consuming, and becoming increasingly impractical due to labour scarcity and unfavourable weather conditions. Herbicide-based weed management provides a potentially more effective and economical solution. Various pre-emergence, early post-emergence, and post-emergence herbicides, as well as herbicide mixtures, are available for comprehensive weed management in blackgram. This review synthesizes recent research on the effectiveness of different herbicides and their combinations in managing weeds in blackgram cultivation.
