Herbicide
PYROXASULFONE 20% OD
A selective pre-emergence herbicide that provides effective residual control of annual grasses and selected broadleaf weeds. It helps ensure early-season weed suppression, promoting healthy crop establishment and improved productivity.
Active: Pyroxasulfone
Formulation: OD (Oil Dispersion)
Selective Pre-Emergence
HRAC Group 15 Action
Product Information
Mode of Action
Pyroxasulfone (HRAC Group 15) inhibits the biosynthesis of very long-chain fatty acids (VLCFAs), preventing root and shoot development during weed germination and emergence. This provides long-lasting residual control of germinating weed seeds.
Target Weeds
- Echinochloa spp.
- Setaria spp.
- Digitaria spp.
- Eleusine indica
- Amaranthus spp.
- Chenopodium album
- Annual grasses and selected broadleaf weeds
Recommended Application Guidance
| Crop | Target Weeds | Dosage & Method of Application |
|---|---|---|
| Maize, Soybean, Wheat, Barley & Sunflower | Annual grasses & selected broadleaf weeds | Apply as a pre-emergence spray immediately after sowing and before weed emergence, as per the recommended label dosage. Ensure adequate soil moisture for optimum herbicide activation and residual weed control. |
For specific ml/ha dosage rates and local spray volume recommendations across registered crops, please refer to the registered product label or consult local agricultural extension specialists.
Application Instructions
1. Pre-Emergence Timing Immediately After Sowing
Apply as a pre-emergence soil treatment immediately after crop sowing and prior to weed seedling emergence. Early application maximizes soil residual efficacy against germinating weeds.
2. Soil Moisture & Activation Requirements
Ensure application is conducted on moist soil or followed by light rainfall/irrigation to incorporate the herbicide into the topsoil layer, activating the VLCFA inhibition mechanism in germinating weed seeds.
Safety & Environmental Care
Always wear appropriate personal protective equipment (gloves, goggles, face mask, protective suit) during handling, mixing, and application. Avoid spray drift onto non-target crops and nearby water bodies. Store in original sealed container in a cool, dry, well-ventilated location away from food, drink, and animal feed.
