Mepiquat Chloride – Targeted Growth Regulation for Yield Optimization
Mepiquat Chloride is a systemic plant growth regulator (PGR) designed to optimize plant architecture, reduce lodging risk, and enhance crop yield quality through precise hormonal control. As an anti-gibberellin agent, it works by inhibiting the biosynthesis of gibberellic acid, the hormone responsible for excessive stem elongation. This leads to shorter internodes, stronger stems, improved root development, and better nutrient partitioning—factors that collectively contribute to healthier, more productive crops.
POMAIS offers mepiquat chloride in multiple high-quality formulations including 5% aqueous solution (widely used in foliar spraying) and 98% technical concentrate, suitable for downstream processing or use as an intermediate in other agrochemical products. Our mepiquat chloride is produced under strict quality control systems and adheres to global standards for purity, efficacy, and safety.
This product is particularly effective in cotton—where it regulates vegetative growth, boosts boll formation, and improves fiber quality. It is also widely used in rice, wheat, rapeseed, and soybeans, especially in regions prone to lodging and excessive vegetative growth during high-fertility or rainy seasons.
Key Functional Advantages:
- Restrains apical dominance and promotes balanced crop development.
- Enhances reproductive growth by redirecting plant energy toward seed, boll, or fruit production.
- Reduces crop lodging, particularly in tall cereals and cotton under dense planting conditions.
- Improves harvest uniformity, earliness, and commercial value of final yields.
- Increases plant resistance to abiotic stresses like wind, rain, and nutrient imbalance.
As a core component of modern agronomic strategies, Mepiquat Chloride is often integrated into IPM and nutrient management programs to regulate canopy size and improve mechanized harvesting outcomes.
Whether you are a formulation buyer, agrochemical distributor, or PGR brand owner, POMAIS delivers stable supply, tailored packaging, and compliance documentation (COA, TDS, MSDS, GLP reports) to support your registration or marketing activities across Asia, Latin America, and Africa.
Mode of Action – How Mepiquat Chloride Regulates Growth
Mepiquat Chloride functions primarily as an anti-gibberellin plant growth regulator, targeting the gibberellin biosynthesis pathway within plant cells. Gibberellins are hormones that stimulate stem elongation, cell division, and vegetative growth. By inhibiting their production, mepiquat chloride effectively slows down excessive shoot growth and encourages a shift in plant energy allocation from vegetative tissues toward reproductive development.
Mechanism Summary:
- Inhibits gibberellic acid biosynthesis in meristematic regions.
- Reduces internodal cell elongation, resulting in shorter, sturdier stems.
- Promotes assimilate partitioning toward fruit, seed, or boll development.
- Enhances root system growth and nutrient uptake capacity.
- Improves lodging resistance in cereals and cotton by strengthening basal stem tissues.
Unlike contact-type products, mepiquat chloride is absorbed through leaves and stems, then translocated systemically throughout the plant. This allows for broad, even effect with foliar applications, especially in crops such as cotton, rice, and soybeans where uniform growth regulation is critical.
This mechanism makes mepiquat chloride a vital tool for managing crop uniformity, stress resistance, and yield predictability, especially under high-input agricultural systems.

Field Applications & Use Scenarios
Mepiquat chloride is widely used as a plant growth regulator across diverse agricultural production systems. Its ability to inhibit excessive vegetative growth, reduce plant height, and enhance reproductive development makes it particularly valuable in row crops, especially in environments with high nitrogen availability or dense planting systems.
Cotton Cultivation
In cotton farming, mepiquat chloride is a standard component of growth management programs:
- Purpose: To shorten internodes, reduce lodging risk, and promote earlier boll opening.
- Application Timing: From early squaring to mid-flowering stage, depending on plant height and weather conditions.
- Result: Improved canopy structure, better light penetration, and synchronized maturation, leading to higher lint yield and better fiber quality.
This use case is particularly effective in high-density cotton planting or under excess nitrogen conditions where vegetative growth threatens boll retention.
Cereal Crops (Wheat, Barley)
Although less common, mepiquat chloride is occasionally used in cereal crops:
- Purpose: To reduce lodging in high-fertility systems and support robust ear development.
- Typical Regions: Applied in areas where high nitrogen or irrigation increases plant height vulnerability to wind damage.
Ornamental Plants and Turfgrass
Mepiquat chloride finds selective application in ornamental horticulture and turf management:
- Use Cases:
- Control of excessive shoot elongation in greenhouse-grown plants.
- Maintaining compact plant forms in bedding plants and floral displays.
- Managing vertical growth in sports turf and landscape lawns.
Vegetable Crops & Oilseeds (Region-Specific)
In some regions (e.g., Southeast Asia and South America), mepiquat chloride has experimental or registered use in:
- Tomatoes & Peppers: Reducing vegetative biomass to improve fruiting ratio.
- Canola & Soybean: Supporting compact growth for mechanical harvesting systems.
FAQ – Common Questions About Mepiquat Chloride
Q1: What is the primary function of mepiquat chloride in crop production?
A: Mepiquat chloride functions as a plant growth regulator (PGR), mainly by inhibiting gibberellin biosynthesis. It restricts excessive vegetative growth, shortens internodes, and promotes reproductive development, improving yield structure in crops such as cotton and cereals.
Q2: Is mepiquat chloride safe for crops under high-temperature or drought stress?
A: Yes, when applied at the correct stage and dosage, mepiquat chloride helps crops adapt to environmental stress by improving resource allocation. However, avoid applying during extreme heat or drought stress peaks to prevent phytotoxicity.
Q3: Can I mix mepiquat chloride with other foliar fertilizers or pesticides?
A: Mepiquat chloride is generally compatible with most common foliar fertilizers and pesticides. However, it is recommended to conduct a small jar test or consult technical support before large-scale tank mixing to confirm chemical stability and leaf surface behavior.
Q4: How long does it take for mepiquat chloride to show visible effects on plants?
A: Effects typically begin to appear within 3–7 days post-application, including reduced elongation and more compact growth habit. Full physiological impact becomes evident in 10–14 days depending on temperature and plant metabolism.
Q5: What is the shelf life of mepiquat chloride formulations?
A: Most mepiquat chloride products have a shelf life of 2 years when stored in original, sealed containers under cool and dry conditions, away from direct sunlight.
Q6: Is mepiquat chloride suitable for use in organic farming systems?
A: No. Mepiquat chloride is a synthetic plant growth regulator and is not approved for organic agriculture under current international organic standards.
Q7: What precautions should be taken during application?
A: Operators should wear appropriate protective gear, avoid contact with skin or eyes, and prevent drift onto non-target crops. Always follow the application instructions on the label and adhere to local safety regulations.
