Weed control

Chemical weed control

Pre-emergence application of oxadiazon 1 kg/ha or pre-plant incorporation of fluchloralin or trifluralin 1 kg/ha have been found quite effective.

Mechanical weed control

Give one or two hoeings/ harrowings at 25 to 30 and 45 to 50 days after sowing depending on the length of rosette period and the severity of weed infestation.

Give one additional interculture or hoeing using bullock drawn hoes/ harrows/ sweeps in December before the crop canopy is closed and the spines become problematic.
