Methods and Dosage of Chlormequat Chloride Use
The methods and dosage of chlormequat chloride generally depend on the crop being treated. For example, when used on peppers during the budding to flowering stage, the dosage is 20-25mg/L, sprayed on the stems and leaves. If used on potatoes, the dosage is 600-2500mg/L, applied during the budding to flowering stage, mainly sprayed on the leaves, which can increase potato yield.
Chlormequat chloride is a low-toxicity plant growth regulator that can be used not only in vegetable and grain crops but also on fruit trees.
Crops such as wheat, rice, sorghum, peanuts, soybeans, tomatoes, cucumbers, potatoes, and even sugarcane, apples, peaches, citrus, and pears can all use it.
Although the use of chlormequat chloride on crops can promote plant reproductive growth, increase lodging resistance, increase chlorophyll, promote photosynthesis, and improve fruit setting rate.
However, improper use can still lead to phytotoxicity issues. How to use chlormequat chloride correctly?
As a pesticide that can increase crop yield, the use of chlormequat chloride by farmers is very widespread. But do you know the correct way to use chlormequat chloride?
Correct use of chlormequat chloride can achieve twice the result with half the effort. Here are some simple introductions to the methods of using chlormequat chloride for several common crops.
Method One: Seed Treatment with Chlormequat Chloride for Strong Seedlings
(1) Wheat:
Apply 2% to 3% solution to seeds, then let them sit for 12 hours before sowing. This can make seedlings stronger, root systems more developed, tillering more, and increase yield by about 12%.
Applying 0.15% to 0.25% solution in the early tillering stage can make wheat seedlings shorter and stronger, increase tillering, and increase yield by 6.7% to 20.1%.
(2) Corn:
Dilute chlormequat chloride 80 to 100 times with water and soak seeds for 6 hours, ensuring the seeds are submerged. After drying in the shade, sow the seeds. This can make the plants shorter and stronger, root systems more developed, ear position lower, no bald heads, larger and fuller ears, and significant yield increase.
Method Two: Common Vegetable Usage and Dosage
(1) Peppers and Potatoes
When peppers and potatoes start to show signs of excessive growth, during the budding to flowering stage, spray potatoes with 1600-2500 mg/L chlormequat chloride on the leaves to control ground growth and promote yield increase.
Peppers can be sprayed with 20-25 mg/L chlormequat chloride on the stems and leaves to control excessive growth and improve fruit setting rate.
(2) Cabbage
Spray the growth points of cabbage (Chinese cabbage) and celery with a 4000-5000 mg/L chlormequat chloride solution to effectively control bolting and flowering.
(3) Tomatoes
During the seedling stage, sprinkle the surface of the soil with a 50 mg/L chlormequat chloride solution to make the tomato plant compact and bloom earlier.
If tomatoes show signs of excessive growth after transplanting, apply a diluted solution of 500 mg/L chlormequat chloride at 100-150 ml per plant. The effect will be evident in 5-7 days and消失 after 20-30 days.
Methods and Dosage of Chlormequat Chloride Use
Method Three: Mid-season Application of Chlormequat Chloride
(1) Wheat
Applying chlormequat chloride at the end of tillering and the beginning of jointing stage can effectively inhibit the elongation of the lower 1-3 internodes of the stem, which is extremely beneficial for preventing wheat lodging and also increases the number of fertile spikes.
(2) Rice
In the early jointing stage of rice, apply 50-100g of 50% aqueous solution per mu with 50kg of water to spray on the stems and leaves of rice. This can make rice shorter and stronger, prevent lodging, and increase yield.
(3) Corn
Applying chlormequat chloride before jointing can shorten the internodes of corn, reduce ear position, increase lodging resistance, make leaves shorter and wider, enhance photosynthesis, reduce bald tops, increase 1000-grain weight, and ultimately achieve yield increase.
In the specific use of chlormequat chloride, different crops have different dosages and usage methods. However, it is particularly important to note that chlormequat chloride should not be mixed with any alkaline fertilizers, as mixing with alkaline fertilizers will cause chlormequat chloride to decompose and lose its effect.
