What are the benefits of spraying mepiquat chloride on cotton?

Mepiquat chloride is a growth regulator specifically for cotton, with the effects of controlling excessive vegetative growth in cotton, regulating nutrient distribution, and increasing boll set. Entering September, cotton growth and development have reached the late boll-setting stage, so spraying an appropriate amount of mepiquat chloride, at 20 milliliters per mu, can reduce the occurrence of ineffective flower buds.

After spraying on cotton, the leaves become greener and the leaf flesh thicker, which can effectively enhance cotton photosynthesis. After cotton is sprayed with mepiquat chloride, it can also make the fruiting branches in the upper part of the cotton plant grow sturdy, reducing the impact of pests such as cotton bollworm and tobacco cutworm. At the same time, in recent years due to climate effects, cotton tends to grow too vigorously in the late growth stage, with many superfluous buds in the upper part, consuming a large amount of nutrients and affecting the filling of the upper cotton bolls, so manual removal is needed; after spraying with mepiquat chloride, the occurrence of superfluous buds can be effectively reduced, saving labor input.
