Diquat 200g/L SL

Mode of Action

• Mechanism: Inhibits electron transfer in photosynthesis, leading to the formation of reactive oxygen species (e.g., hydrogen peroxide).
• Action Speed: Visible wilting within 24 hours of application; complete foliage desiccation within days.
• Systemic Traits: Slightly systemic, but primarily acts on contacted green tissues; does not translocate significantly in plants.

Target Weeds & Applications

Formulations & Dosages

Common Formulations

• Soluble Liquid (SL): 10% SL, 20% SL, 37.4% SL, 200g/L SL (ideal for foliar and aquatic applications).
• Emulsifiable Concentrate (EC): Available in various concentrations for broader mixing flexibility.

Application Rates

Key Features & Benefits

1. Rapid Action: Visible effects within 24 hours, ideal for emergency weed control.
2. Broad-Spectrum Efficacy: Effective against annual broadleaf weeds and some grasses; particularly potent on aquatic weeds like water hyacinth.
3. Low Soil Residue: Strongly adsorbed by soil colloids, minimizing residual toxicity to subsequent crops.
4. Photodegradable: 80% photolyzed within 4 days under sunlight, reducing environmental persistence.
5. Cold Tolerance: Performs better than glufosinate ammonium in temperatures below 15°C.
6. Tank Mix Compatibility: Can be mixed with glyphosate for expanded weed control spectrum.

Safety & Handling

• Pre-Harvest Interval (PHI): 7–10 days to ensure minimal residue on harvested crops.
• Precautions:
  • Avoid spraying on young crop trees or green bark to prevent phytotoxicity.
  • Use protective gear (gloves, goggles) during application.
  • Keep away from water sources; avoid runoff into rivers or ponds.
• Storage: Store in cool, dry conditions; protect from direct sunlight.

Packaging & Distribution

• Small Packaging: 500ml, 1L, 5L bottles for small-scale users.
• Bulk Packaging: 25L drums, 200L drums, 1000L IBC containers for commercial agriculture.
• Global Reach: Exported to Africa, South America, and Southeast Asia; supports OEM/ODM services for custom labeling and formulations.

Environmental Considerations

• Aquatic Use: Effective for submerged weed control but must be applied carefully to avoid harming non-target aquatic organisms.
• Soil Impact: Non-persistent in soil; safe for use in conservation tillage systems.

Diquat Dibromide Herbicide FAQ

1. What is Diquat Dibromide, and how does it work?

2. What types of weeds does Diquat control?

• Primary targets: Annual and perennial broadleaf weeds (e.g., water hyacinth, dock weeds, lambsquarters).
• Secondary control: Some grassy weeds (e.g., barnyardgrass), though less effective on grasses than broadleaf species.
• Aquatic use: Effective against submerged and floating weeds in ponds, canals, and irrigation systems.

3. Where is Diquat typically applied?

• Agricultural crops: Potatoes, cotton, soybeans, corn (pre-harvest desiccation to dry green tissues and weeds).
• Non-crop areas: Orchards, vineyards, roadsides, and industrial sites for broad-spectrum weed control.
• Aquatic environments: Management of invasive aquatic plants like water hyacinth and duckweed.

4. What are the common formulations of Diquat?

• Soluble Liquid (SL): 10% SL, 20% SL, 200g/L SL (most common for foliar and aquatic applications).
• Emulsifiable Concentrate (EC): Used for tank mixing with other pesticides.
• Application forms: Foliar sprays, soil treatments (limited systemic action), and sub-surface aquatic applications.

5. How should Diquat be applied for best results?

• Timing: Apply to young, actively growing weeds (pre-flowering stage) for maximum efficacy.
• Method:
  • Foliar spray: Ensure uniform coverage of weed foliage; use ground equipment for precision.
  • Aquatic systems: Apply as a sub-surface spray to target submerged weeds without excessive drift.
• Mixing: Easily soluble in water; mix with glyphosate or other herbicides for broader weed control.

6. Is Diquat safe for the environment?

• Soil safety: Strongly adsorbed to soil particles, minimizing leaching and residual toxicity to subsequent crops.
• Water safety: Toxic to aquatic life (fish, algae, invertebrates), so avoid application near water bodies or during windy conditions to prevent runoff.
• Biodegradation: Rapidly photolyzed (80% degradation within 4 days under sunlight), reducing persistence in the environment.

7. What are the safety precautions when using Diquat?

• Personal protection: Wear waterproof gloves, goggles, and long sleeves to avoid skin/eye contact.
• Crop safety: Avoid spraying on young trees or green bark, as it may cause phytotoxicity.
• Storage: Store in original containers, away from food, water, and heat sources.
• Disposal: Follow local regulations; do not pour excess product into waterways.

8. Can Diquat be used in organic farming?

9. How does Diquat compare to Paraquat?

10. What is the pre-harvest interval (PHI) for Diquat?

11. Does Diquat work in cold temperatures?

12. How to manage resistance to Diquat?

• Rotation: Avoid continuous use; rotate with herbicides from different modes of action (e.g., glyphosate, acetolactate synthase inhibitors).
• Tank mixes: Combine with other herbicides (e.g., glyphosate) to target multiple physiological pathways and reduce resistance risk.

13. Can Diquat be used on aquatic weeds without harming fish?

• Use approved formulations for aquatic use.
• Apply at low rates and avoid overspray into water bodies.
• Consult local environmental regulations before use in or near water.

14. What is the shelf life of Diquat?

15. Is Diquat harmful to humans?

• Toxicity: Moderate toxicity if ingested or absorbed through skin; causes irritation to eyes and skin.
• Safety measures: Follow label instructions for protective gear and avoid inhaling spray mist. In case of exposure, rinse thoroughly and seek medical attention.
