WEED CONTROL
WEED CONTROL
- Hand weeding is the only recommended weed control method after broadcasting or dibbling in rain fed rice
- Weeds should be uprooted and taken far away from the plots and destroyed either by burning or deep burying
- Cono weeder can be used in any systematic planted rice fields apart from SRI, that has adequate row spacing, when weeds are still young
- Rotate rice with other crops where there is a heavy infestation of the weeds
- Use of chemicals and hand weeding are recommended for irrigation schemes
- Ronstar 25 EC herbicide should be applied at the rate of 3 liters in 300 liters of water per hectare using a sprayer. The application should be done soon after transplanting within 3 days, on moist soil. Irrigation water should be applied after 3 days for effective use of the chemicals
- Proper water control helps to reduce weeds that do not withstand submergence.
- One common difficult weed is Nadanga (Echinochloa crusgalli) because it is not easy to distinguish the weed from rice until flowering stage.
- Farmers need to be taught how distinguish rice from Nadanga weed as they look almost the same.
- Farmers are encouraged to frequently monitor the fields and uproot the weed
- One way of differentiating rice from Nadanga is by planting rice in rows or lines.
- Weeds should be uprooted and taken far away from the plots and destroyed either by burning or deep burying
- You can also rotate with maize so that you can identify Nandanga leave the plot uncultivated for one year so that the weeds should die.
