Weed management

• More vulnerable during initial growth of 50-60DAS.
• shorten the fibre
• staining of lint
• difficulty in ginning
• interfere picking

Mechanical methods

• Tillage, Hoeing, Inter-row Cultivation, fallow system,
• Flooding, Mulching and burning.
• hoeing before 1st irrigation/ after 1 month of sowing found more effective in weed control.

Crop-based approaches

• Competitive crop cultivation
• Crop rotation- with wheat, chickpea, berseem
• Intercropping– Finger millet, groundnut, chillies, sesamum
• Increasing plant population

Chemical methods of weed management

a. Pre-plant:

• Trifuralin @0.5-1.5 kg/ha
• Fluchloralin @0.75-1.5 kg/ha
• Pendimethalin @1.2-1.5 kg/ha

b. Pre-emergence:

• Diuron @0.5-1.5 kg/ha
• Flurometuron @1.0-1.5 kg/ha
• Alachlor @1.5-3.0 kg/ha

[applied by making solution in 1000L of water to the field after the crop grows to 15 cm]

c. Post-emergence:

• Metribuzin, Bentazol, Methzol can be used as post emergence.
