• Target Weeds: Effective against grasses, broad-leaved weeds, and some sedges (e.g., Echinochloa Colonum).
• Mode of Action:
  • Clomazone: Inhibits chlorophyll synthesis, causing bleaching in weeds.
  • 2,4-D Ethyl Ester: Acts as a synthetic auxin, causing uncontrolled growth and death in broadleaf weeds.
• Dosage & Usage: Recommended application is 1.25 liters per hectare for paddy, mixed with 500 liters of water. It is best applied 3-5 days after transplanting.
• Environmental Impact: Studies indicate that while the herbicide is effective, it has a short soil half-life (1.061.27 days for Clomazone, 4.746.24 days for 2,4-D) and low risk to soil organisms.
• Safety Advice: Store in a cool, dry place, separate from food and feed. It is important to avoid spraying near sensitive, non-target crops
