How to control broadleaf weeds in my chana (gram) crop?

Chana (gram) is sensitive and has fewer registered herbicide options than cereals, so weed control leans heavily on pre-emergence chemicals plus cultural and mechanical methods. A reliable step is a pre-emergence spray of pendimethalin within 1 to 3 days of sowing on a moist field, which controls many early grasses and broadleaf weeds including bathua before they emerge. For grassy weed escapes, a post-emergence grass killer such as quizalofop can be used safely in chana. Broadleaf-specific post-emergence options in pulses are limited and must be used very carefully and only if registered for chana, since the wrong broadleaf herbicide can damage the crop, which is why pre-emergence plus one inter-cultivation or hand weeding at about 30 to 35 days is the common, safe combination. Keep a dense, even stand and proper spacing so the crop competes well. Use only herbicides registered for chana, follow the label dose and timing exactly, and confirm with your local KVK before spraying, because pulses are sensitive and a wrong herbicide can kill the crop.
