What to Do About Chlormequat Phytotoxicity? A Detailed Guide to Effective Remedial Methods

Symptoms of chlormequat phytotoxicity: severe stunting of the plant, fruit branches unable to extend, deformed leaves, claw-like leaves appearing, excessive sprouting of adventitious buds, internodes of fruit branches too short, plant branches and leaves brittle and easily broken. For seed-soaking phytotoxicity: roots curved, young leaves severely stunted, emergence delayed, and after emerging more than 7 days later the seedlings appear twisted and deformed. Chlormequat tends to cause phytotoxicity in dicotyledonous plants, but not easily in monocotyledonous plants. Chlormequat phytotoxicity generally does not affect the following crop.

So what should be done about chlormequat phytotoxicity?

You can use Life No. 1 + Baomeiling, the Apollo 963 chitosan series of products, Yunda 120, Aiduoshou, cytokinin, and so on.

Chlormequat is a micro-dose, high-efficiency plant growth regulator that inhibits crop cell growth but cannot inhibit cell division. Under suitable temperature conditions, it can control vegetative growth and promote reproductive growth. However, cotton is relatively sensitive to chlormequat; if the mixed concentration is too high or the dosage too large, it will inhibit cotton growth, making the cotton plant too short, with poor ventilation and light penetration, easy shedding of squares and bolls, and even deformed cotton bolls; leaves take on a watermelon-leaf appearance, leaves become wrinkled, the plant becomes excessively stunted, and bolls are small.

Chlormequat is a low-toxicity plant growth regulator that can enter the plant body through leaves, young branches, buds, roots and seeds. It can control excessive vegetative growth, shorten internodes, make plants short, sturdy and thick with well-developed root systems and resistance to lodging. At the same time, leaf color deepens, leaves thicken, chlorophyll content increases, and photosynthesis is enhanced, thereby increasing the fruit-setting rate of certain crops, and also improving quality and increasing yield. Chlormequat can also improve the ability of certain crops to resist drought, cold, salinity and alkalinity, and certain diseases and insect pests. It is suitable for addition to fertilizer products such as water-flush fertilizers, foliar fertilizers and root-applied fertilizers, promoting nutrient absorption and regulating growth.
