Diquoshi Herbicide | 1L is a rapid-contact, non-selective herbicide used for quick burndown of broadleaf weeds, grasses, and desiccation (drying) of crops pre-harvest. It disrupts plant cell membranes on contact, causing visible wilting within hours. Ideal for industrial sites, aquatic weed control (restricted formulations), and crop desiccation. Key Specifications of Diquoshi Herbicide | 1L: Active Ingredient: Diquat Dibromide: 200–400 g/L (commonly 240g/L or 400g/L). Chemical Class: Bipyridyl herbicide (similar to Paraquat, but less persistent). Mode of Action: Contact Killer: Destroys green tissue on contact (no root translocation). Light-Dependent: Requires sunlight to activate. Speed: Visible effects in 30 mins–2 hours; complete kill in 1–7 days. Target Weeds: Annual grasses (e.g., barnyard grass), broadleaf weeds (e.g., pigweed), and aquatic plants. Desiccation: Potatoes, cotton, sunflowers pre-harvest. Applications of Diquoshi Herbicide | 1L: Non-Crop Areas: Clear weeds in industrial sites, roadsides, or fence lines. Dosage: 2–4 L/ha in 200–400L water. Aquatic Weed Control: Only if labeled for aquatic use: Treat submerged/emergent weeds in ponds/drains. Rate: 1–2 L per surface acre (follow local regulations). Crop Desiccation: Apply 1–2 L/ha to potatoes, oilseed rape, or sunflowers 7–14 days pre-harvest. Spot Treatment: Use 10–20ml per liter of water for knapsack spraying. Safety & Precautions: High Acute Toxicity: Oral LD50: ~230 mg/kg (fatal if swallowed). Dermal/Irritation: Corrosive to skin/eyes; causes severe burns. Mandatory PPE: Gloves, goggles, respirator, coveralls. Environmental Risks: Highly toxic to fish/aquatic life – avoid water contamination. Soil Binding: Inactivated upon soil contact (no residual activity). Regulatory Status: Banned in the EU (since 2018) due to health risks. Restricted use in USA, Australia, and other regions (requiring license). Usage Guidelines: Mixing: Add 100–200ml to 100L water (general weed control). Use non-ionic surfactant for enhanced adhesion. Timing: Apply during active weed growth on sunny days. Avoid rain for 6 hours. 1L Coverage: Non-Crop: 0.25–0.5 ha (at 2–4 L/ha). Spot Treatment: Treats ~1,000–2,000m².
