Mepiquat Chloride is a plant growth regulator (PGR) widely used in cotton, cereals, and other crops to control excessive vegetative growth.It helps improve plant architecture, enhance stress tolerance, and increase yield potential by regulating plant height, promoting stronger stems, and optimizing nutrient allocation.
Mepiquat Chloride works as a gibberellin biosynthesis inhibitor:
Inhibits the production of gibberellins, plant hormones responsible for cell elongation
Reduces excessive stem elongation, resulting in shorter, sturdier plants
Improves branching and boll retention in cotton and enhances lodging resistance in cereals
Promotes better nutrient allocation to reproductive organs rather than excessive vegetative growth
Effects are usually visible within 7–14 days after application.
✔ Regulates plant growth – Controls excessive height and promotes sturdy stems
✔ Enhances yield – Improves boll retention and grain filling
✔ Improves crop quality – Optimizes plant architecture for better light penetration
✔ Stress tolerance – Helps plants withstand lodging, drought, and other stress conditions
✔ Flexible application – Compatible with most cotton and cereal production programs
⚠ Apply during active vegetative growth; avoid stressed crops
⚠ Follow recommended dosage and timing based on crop type and growth stage
⚠ Avoid over-application, which may reduce plant height excessively
⚠ Use proper personal protective equipment (PPE) during application
⚠ Always follow local registration and crop-specific guidelines
Multiple applications may be used depending on crop growth, but do not exceed the recommended total dosage.
Q1: What crops can Mepiquat Chloride be used on?
A: Mainly cotton, cereals (wheat, rice), and some horticultural crops.
Q2: How does it work?
A: It inhibits gibberellin biosynthesis, reducing excessive stem elongation and promoting sturdier plants.
Q3: When should it be applied?
A: During active vegetative growth, before flowering or rapid elongation stages.
Q4: How soon are results visible?
A: Plant growth changes can typically be observed 7–14 days after application.
Q5: Can it be combined with other agrochemicals?
A: Yes, compatible with many insecticides and herbicides, but always follow local recommendations.
Q6: Do you provide OEM or custom packaging?
A: Yes, we support OEM, labeling, and packaging customization according to customer requirements.
