Evaluation of broad-leaved herbicides for the management of Tarkandi Palak (Emex spinosa L.) in wheat (Triticum aestivum L.) crop
Broad-leaved weeds significantly constrain wheat productivity by competing for nutrients, water, and light. A field experiment was conducted to evaluate the efficacy of different post-emergence herbicides against a broad-leaved weed local known as palaki pakhra or tarkandi palak in wheat. Six treatments including fluroxypyr-based mixtures, sulfonylurea herbicides, and bromoxynil combinations were tested in a randomized complete block design (RCBD) with three replications. Results indicated that herbicide treatments significantly reduced weed density (P < 0.05) but had a non-significant effect on yield (P > 0.05). The treatment bromoxynil + MCPA (T5) produced the highest yield (468 g m⁻²) and maximum weed reduction (61.11%). Herbicide mixtures proved more effective than single active ingredients. These findings support integrated weed management strategies for sustainable wheat production.
