- Crops: Primarily used in wheat, rice, and sugarcane to manage weeds effectively. It is also suitable for other cereal crops like barley and oats, and in alfalfa and some vegetables and ornamentals.
- Non-Crop Areas: Can be applied to manage weeds in areas like driveways, patios, and fence lines.
Mechanism of Action
- Systemic Action: Absorbed by weed roots and foliage, then moves throughout the plant.
- Inhibition of Growth: It inhibits cell division in the meristematic tissues (growing points) of the roots and shoots.
- Broad-Spectrum Control: Controls both annual and perennial broadleaf and grassy weeds by affecting their essential growth processes.
Key Characteristics
- Selective: Safe for the target crops (like wheat) when applied according to label instructions, as it does not damage the crop itself.
- Post-Emergence: Applied after the weeds have emerged from the soil.
- Contact and Residual Activity: Offers immediate kill of weeds upon contact and provides long-lasting control due to its soil and foliar activity.
- Soil Half-Life: Has a short half-life in the soil, meaning it degrades quickly and typically does not harm subsequent crops.
- Rain-Fastness: Achieves good rain-fastness shortly after application, meaning it won't wash off easily.
Important Considerations
- Dose and Application: Proper dosage (e.g., 8 grams per acre for wheat/rice) and dilution with water (e.g., 150-200 liters per acre) are crucial for effectiveness and crop safety.
- Timing: Apply when weeds are in their early growth stage (e.g., 3-4 leaves) for best results.
- Environmental Safety: While generally safe for neighboring crops, responsible use is essential to minimize environmental impact.
- Surfactants: Adding a surfactant can enhance its efficiency, especially when targeting grasses.
