Cotton field specific herbicide Tidiazuron 360 g/l + Diuron 180 g/L SC Tidiazuron 120 g/l + Diuron 60 g/L SC

1. Product Overview

2. Mechanism of Action & Product Performance

2.1 Dual Synergistic Working Mechanism

2.2 Core Product Advantages

• Superior Synergistic Efficacy: The compound formula complements the advantages of slow and thorough defoliation of thidiazuron and fast desiccation of diuron. It achieves rapid leaf drying in 3–5 days and complete defoliation in 7–14 days, with a defoliation rate of over 90%, far better than single-agent products.
• Improve Cotton Quality & Yield: It promotes concentrated opening of cotton bolls, reduces immature bolls and late-opening bolls, increases the proportion of first-grade cotton. It effectively avoids leaf debris mixing into cotton during harvesting, reduces cotton contamination, improves lint cleanliness and fiber quality, and increases cotton yield by 5%–10% compared with conventional defoliation methods.
• Professional SC Formulation: Adopts advanced suspension concentrate process, with ultra-fine active ingredient particles, stable suspension system, no layering, no precipitation during storage. It disperses quickly and evenly in water, has strong adhesion on crop stems and leaves, resists slight rain wash, and high pesticide utilization rate. Zero dust pollution, safer for operators and ecological environment than powder formulations.
• Wide Adaptability & Long Effective Period: Suitable for all varieties of upland cotton. It adapts to different temperature environments (effective when the minimum night temperature is above 12°C). The efficacy is stable and lasting, which can fully meet the time cycle requirements of large-scale mechanical harvesting.
• Cost-Effective & Labor-Saving: High-concentration compound formula reduces application dosage and frequency. One-time application can complete defoliation and ripening treatment, saving labor and time costs, and significantly reducing pre-harvest management investment of cotton fields.
• Standard Harvest Support: Thorough defoliation provides a clean picking environment for mechanical cotton picking, effectively reduces mechanical picking impurity rate, improves harvesting efficiency, and is fully compatible with modern large-scale cotton planting and harvesting modes.

3. Detailed Application Methods & Dosage

3.1 Target Crop & Purpose

3.2 Optimal Application Timing

• The best application period is when the cotton boll opening rate reaches 40%–50% or the lower branch boll opening rate exceeds 30%.
• Apply when the minimum night temperature is stably above 12°C to ensure normal absorption and efficacy exertion; avoid application in low temperature, rainy and cloudy weather for a long time.
• Each cotton field is limited to one application per growing season to avoid excessive treatment affecting cotton quality.

3.3 Recommended Dosage & Usage

• Standard Dosage: 15–25 mL per mu (667㎡); 225–375 mL per hectare
• Dosage Adjustment: In high temperature, sufficient light and well-matured cotton fields, use low dosage; in low temperature, late maturity and vigorous cotton growth fields, appropriately increase the dosage within the recommended range.
• Application Method: Stem and leaf uniform spraying. Dilute the product with 25–30 kg of clean water per mu, and evenly spray on cotton stems, leaves and boll surfaces, focusing on dense foliage areas to ensure full coverage of the whole plant.

3.4 Solution Preparation & Operation Specifications

• Adopt the secondary dilution method: First pour a small amount of clean water into the sprayer, add the required dosage of the product, stir fully to form a uniform mother liquor, then add water to the standard volume and stir again before spraying.
• Use clean neutral water for dilution; do not use alkaline water, sewage or turbid water to avoid reducing efficacy.
• Complete the spraying operation in calm morning or evening; stop operation in case of strong wind, heavy rain or sudden temperature drop.
• Do not mix with alkaline pesticides, foliar fertilizers and herbicides to prevent ingredient decomposition and phytotoxicity.

4. Packaging Specifications

• Small Portable Packaging: 250mL/bottle, 500mL/bottle (high-quality plastic sealed bottle, portable, easy for small-area field application and retail sales)
• Medium Commercial Packaging: 1L/bottle (standard agricultural packaging, suitable for small and medium-sized cotton planting bases)
• Large Bulk Packaging: 5L/bottle, 10L/bottle (industrial bulk packaging, cost-effective for large-scale farms and pesticide distributors)

5. Storage Conditions & Shelf Life

• Storage Requirements: Store in a cool, dry, ventilated and dark sealed warehouse. Keep away from direct sunlight, high temperature, humidity, fire sources and strong oxidizing substances. Strictly isolate from food, feed and drinking water to avoid pollution. Tighten the bottle cap immediately after opening to prevent moisture ingress and liquid deterioration.
• Shelf Life: 2 years for unopened original package under normal specified storage conditions.

6. Precautions

• Wear professional protective equipment including rubber gloves, protective masks and work clothes during solution preparation and spraying operation to avoid skin contact and respiratory inhalation.
• It is forbidden to eat, drink and smoke during operation. After work, thoroughly clean hands, face and exposed skin with clean water, and clean spraying tools.
• Avoid pesticide drift to adjacent crops, vegetable fields, fruit orchards and water bodies to prevent phytotoxicity and environmental pollution.
• Pesticide waste liquid and empty packaging bottles must be disposed of in accordance with local environmental protection and pesticide management regulations, and shall not be discarded randomly.
• In case of accidental ingestion, skin irritation or eye contact, rinse the affected area with plenty of clean water immediately and seek medical treatment in time with the product label.
• Keep out of reach of children, pregnant women, the elderly and livestock.
