Weed Control Practices for Sugarcane Field:
1. Blind hoeing is performed after planting one hand weeding and 2 to 3 row cultivations are done. After earthling up no physical method is feasible.
2. Pre Emergence Control:
Atrazine and Simazine 1 to 2 kg/ha controls weeds up to 4-6 weeks CDAA (6-10 kg/ha) gives more effective control.
3. Early Post Emergence Control:
Paraquat (Non-residual) 0.5 to 1 kg/ha. MSWA and DSMA (2-3 kg/ha). Amitrol 0.2 to
1%.
4. Control of Nut Sedge:
Pre-planting use of Vernolate (3-4kg/ha) also controls annual grasses along with nut sedge. Also parauat MAA Amitral and Herbicidal oils are used for nut sedge control.
5. Control of Broad leaf Weed:
Post emergence 2,4-D Pichloram and Silvex.
6. Control of Established Grasses:
Dalapon (0.5 to 1%) to control Bermuda grass. Ipomea herdrosa – 80% Sodium salt of 2,4-D within 15 days.
