How to control weeds in mustard (sarson) crop?

Mustard (sarson) is itself a broadleaf crop, so broadleaf weedicides like 2,4-D cannot be used on it, which is why weed control in mustard relies mainly on pre-emergence herbicide 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, well-prepared field, which controls many early grasses and broadleaf weeds before they emerge. For grassy weed escapes later, a post-emergence grass killer such as quizalofop is safe in mustard and clears grasses without harming the crop. Broadleaf weeds that escape are usually removed by one hand weeding or inter-cultivation at about 20 to 30 days, which also helps thin the crop to the right spacing. A dense, even stand from proper seed rate competes well against weeds. Keep hormone weedicides like 2,4-D well away, since mustard is very sensitive to their drift. Use only herbicides registered for mustard, follow the label dose and timing, and confirm with your KVK, because the wrong herbicide can kill this sensitive broadleaf crop.
