How It Works: Mode of Action
Srizon acts as a systemic herbicide that targets the energy production system of weeds.
[Image of photosynthesis inhibition in plants]- Root Absorption: When applied to moist soil, the herbicide is absorbed by the roots of germinating weeds.
- Energy Blockage: It travels up to the leaves and blocks "Photosystem II," stopping the plant from converting sunlight into food.
- Weed Death: The weed starves, turns yellow (chlorosis), and dies, while the maize or sugarcane crop naturally detoxifies the chemical.
Note: Soil moisture is critical for the herbicide to enter the root system.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Trianthema (Carpet weed), Amaranthus, Digera, and other broadleaf weeds. |
| Sugarcane | Broad spectrum of annual weeds and broadleaf complexes. |
| Tank Mix Uses | Used with Glyphosate for burndown in conservation tillage. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Maize (Light Soil) | 400 - 500 g | 200 L | 2.5 g | 60 Days |
| Maize (Heavy Soil) | 800 g | 200 L | 4 g | 60 Days |
| Sugarcane | 400 - 1600 g | 200 - 300 L | 2 - 5 g | NA |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. *Note: Dose is in Grams (g) as Srizon is a Wettable Powder.
How to Apply: Best Practices
- Timing: Apply strictly 0 to 3 days after sowing (Pre-Emergence). Do not wait for weeds to become visible.
- Mixing: As this is a powder, pre-mix the dose in a small amount of water to create a slurry before adding to the main tank.
- Coverage: Use Flat Fan or Flood Jet nozzles for even soil coverage. Do not use cone nozzles.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. When is the best time to spray Srizon?
Immediately after planting, within 3 days. It works best before weeds emerge.
2. Do I need to irrigate after spraying?
Yes. Srizon requires soil moisture to work. If there is no rain, apply light irrigation to activate the chemical.
3. Can I mix it with other herbicides?
Yes. It is often mixed with Metolachlor for grass control or 2,4-D for post-emergence rescue (consult an agronomist).
4. Is it safe for the next crop?
Srizon has residual action. Wait 6-10 months before planting sensitive crops like Soybeans or Wheat.
5. What type of nozzle should I use?
Use a Flat Fan or Flood Jet nozzle. Avoid fine mist nozzles as they increase drift.
