Highly Effective Mepiquat Chloride 5% SL for Plant Growth Regulation Cotton

1. Product Information

Product Name: Mepiquat Chloride 5% SL

Common Name: Mepiquat Chloride

Formulation: Aqueous Solution (SL)

Active Ingredient: 5% Mepiquat Chloride (50 g/L)

CAS No.: 24307-26-4

Molecular Formula: C₇H₁₆ClN

Product Character: This product is a clear, uniform water-soluble liquid, featuring rapid water solubility, no precipitation, no layering, and convenient field application. As a high-efficiency and systemic plant growth regulator, it is widely used for balanced crop vegetative and reproductive growth regulation.

2. Mode of Action

Mepiquat Chloride acts by inhibiting the biosynthesis of endogenous gibberellin in crops, effectively restraining excessive vegetative growth, reducing cell elongation, and shortening internode length. It features strong systemic absorption and conduction, which can be rapidly absorbed by crop leaves and stems and transmitted to the whole plant. Different from growth-promoting regulators, it optimizes crop plant type, coordinates the distribution of photosynthetic nutrients, and promotes the transfer of nutrients from vegetative organs (stems and leaves) to reproductive organs (buds, flowers and fruits), realizing the dual goals of vigorous plant growth and increased yield.

3. Target Crops & Functions

Main Applicable Crops: Cotton, peanut, wheat, rice, soybean, tomato and other vegetables and economic crops

Core Regulatory Functions:

• Control Excessive Growth: Effectively prevents crop overgrowth, lodging and spindling, shortens internodes, thickens stems, and makes plant type compact and neat.
• Improve Canopy Structure: Optimizes field ventilation and light transmission conditions, reduces canopy shading, and lowers the incidence of fungal diseases caused by excessive humidity.
• Promote Reproductive Growth: Increases flower bud differentiation quantity, improves flower and fruit setting rate, reduces flower and fruit dropping, and significantly increases effective bolls and pods of crops.
• Enhance Stress Resistance: Strengthens crop stem toughness and root activity, improves drought resistance, lodging resistance and high-temperature tolerance, and stabilizes crop yield under adverse conditions.
• Improve Quality & Yield: Promotes concentrated nutrient accumulation in fruits and grains, increases crop yield, and improves commodity quality of agricultural products.

4. Application Method & Recommended Dosage

This product is suitable for foliar uniform spraying. Dilute the original liquid with clean water evenly and spray thoroughly on crop leaves and stems; adopt split application according to crop growth vigor for better effect.

General Recommended Dosage: 500–750 mL per hectare, diluted with 300–450 L of clean water for foliar spraying.

Key Application Timing

• Cotton: First spraying at early flower bud stage; supplementary spraying every 10–15 days according to growth status, suppresses vegetative overgrowth and increases cotton boll setting rate.
• Peanut & Soybean: Spray at vigorous vegetative growth stage to prevent lodging, promote pod formation and full grain filling.
• Grain Crops (Wheat, Rice): Spray at jointing stage to control plant height, strengthen stalks, reduce lodging rate, and increase thousand-grain weight.

Application Tips: Do not spray in high temperature, heavy rain or strong wind weather; avoid application on water-stressed, weak or diseased crops to prevent excessive growth inhibition.

5. Product Advantages

• High Efficiency & Stability: Pure active ingredients, stable activity, rapid absorption and quick effect, long-lasting regulation efficacy.
• Water-Soluble & Easy to Use: Fully water-soluble, no blockage of spray nozzles, suitable for manual spraying, mechanical spraying and drone spraying.
• Scientific Growth Regulation: Restrains useless vegetative growth without damaging crop growth vigor, balances nutrition distribution, and realizes healthy and stable growth.
• Wide Compatibility: Can be mixed with most neutral and acidic pesticides and foliar fertilizers to save labor and improve efficiency.
• High Safety: Low toxicity, low residue, safe for crops, humans, livestock and environment, compliant with green agricultural planting standards.

6. Precautions

• Store and use separately from alkaline pesticides and fertilizers to avoid efficacy reduction.
• Wear protective gloves, masks and work clothes during preparation and application; avoid skin contact and inhalation of spray mist.
• Do not eat, drink or smoke during operation. Clean hands, face and exposed skin thoroughly after work.
• Prohibit application in bee breeding areas, silkworm rooms and aquaculture water bodies to avoid ecological hazards.
• Strictly follow the recommended dosage; excessive dosage will cause over-inhibition of crop growth and affect normal yield.
• In case of accidental skin/eye contact, rinse thoroughly with plenty of clean water for more than 15 minutes; if accidentally ingested, seek medical treatment immediately with product label.
• Abandoned liquid and packaging shall be disposed of in accordance with local environmental protection regulations, prohibited from random dumping.

7. Storage & Transportation

• Storage Conditions: Store in cool, dry, ventilated and dark warehouse, keep sealed, avoid direct sunlight, high temperature and freezing.
• Shelf Life: 2 years in original sealed package under normal storage conditions.
• Transportation Requirements: Avoid violent extrusion, collision and package damage during transportation; keep away from food, feed and daily necessities, and comply with international pesticide transportation specifications.

8. Toxicity & Safety Statement

Mepiquat Chloride 5% SL is a low-toxic plant growth regulator. When applied strictly in accordance with the recommended dosage and operation specifications, it is safe for target crops, non-target organisms and ecological environment, with low residual risk and good environmental compatibility.
