With abundant experience, our factory offer high quality chemicals made in China with competitive price. Welcome to contact us for free sample.
Mepiquat Chloride is a plant growth regulator that can inhibit plant elongation, slow down its growth, and increase the synthesis of chlorophyll. It needs to be used multiple times during cotton growth. It is very helpful for enhancing cotton stress resistance, increasing cotton yield, and improving cotton quality.

Mode of action
Mepiquat Chloride has a delayed effect on plant vegetative growth. Mepiquat Chloride can be absorbed by the leaves and roots of the plant and transmitted to the whole plant, which can reduce the activity of gibberellins in the plant, thereby inhibiting cell elongation, weakening the growth of the apical bud, controlling the vertical and horizontal growth of the plant, shortening the internodes of the plant, making the plant compact, the leaf color deep, and the leaf area reduced, and enhancing the synthesis of chlorophyll, which can prevent the plant from growing vigorously and delay the closure of the row. Mepiquat Chloride can improve the stability of the cell membrane and increase the stress resistance of the plant. It is systemic. Spraying according to dosage and different growth stages of plants can regulate plant growth, make plants firm and resistant to lodging, improve color and increase yield. It is a plant growth regulator that is similar to gibberellin and is used on plants such as cotton. The use of methylpyridamole on cotton can promote root development, green leaf color, thicken leaves to prevent excessive growth, resist lodging, increase boll formation rate, increase pre-frost flowers, and improve cotton grade; at the same time, it makes the plant compact, greatly reduces redundant buds, and saves labor for pruning.
Products Applications
1. Control the upper and promote the lower, promote the root system of cotton seedlings, especially the growth of fibrous roots.
2. Enhance the synthesis of chlorophyll, make the leaves of cotton seedlings deep, and improve photosynthesis.
3. Increase the stress resistance of cotton seedlings (that is, enhance the physical fitness of cotton seedlings). Only when the physical fitness is good and strong can it better resist the impact of adverse weather conditions on cotton growth.
4. Generally speaking, in fields where the newly unearthed cotton seedlings are lighter in color, usually yellow-green, thrips and aphids will occur more seriously, because they are more sensitive to color when migrating, especially yellow-green is very attractive to them. At the same time, the seedlings are very tender and delicious to them. Therefore, it is recommended that chemical control and prevention of diseases and insects can be carried out at the same time. Add fungicides and insecticides while chemical control to achieve the purpose of disease prevention and insecticide.
