Main applications of 4-Chlorophenoxyacetic acid (4-CPA)
4-Chlorophenoxyacetic acid (4-CPA) is a phenolic plant growth regulator. 4-Chlorophenoxyacetic acid (4-CPA) can be absorbed by the roots, stems, leaves, flowers, and fruits of plants. Its biological activity lasts for a long time. Its physiological effects are similar to endogenous hormones, stimulating cell division and tissue differentiation, stimulating ovary expansion, inducing parthenocarpy, forming seedless fruits, and promoting fruit setting and fruit expansion.
[Use 1] Used as plant growth regulator, fruit drop preventer, herbicide, can be used for tomato flower thinning and peach fruit thinning
[Use 2] Plant growth hormone, used as growth regulator, fruit drop preventer, herbicide, can be used for tomatoes, vegetables, peach trees, etc., and also used as pharmaceutical intermediates. 4-Chlorophenoxyacetic acid (4-CPA) main application 4-Chlorophenoxyacetic acid (4-CPA) is mainly used to prevent flower and fruit drop, inhibit rooting of beans, promote fruit setting, induce seedless fruit, and has a ripening and growth effect. 4-Chlorophenoxyacetic acid (4-CPA can be absorbed by roots, stems, flowers and fruits, and its biological activity lasts for a long time. The use concentration is 5-25ppm, and trace elements or 0.1% potassium dihydrogen phosphate can be added appropriately. It has a good inhibitory effect on gray mold, and the general use concentration is 50-80ppm.
1. Early yield increase and early maturity.
It works on crops with many ovules, such as tomatoes, eggplants, figs, watermelons, zucchini, etc. Spray eggplants with 25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA solution during flowering, twice in a row, with an interval of 1 week each time. When tomatoes are halfway through blooming, spray them with 25-30 mg/L 4-Chlorophenoxyacetic acid (4-CPA solution once. Peppers are sprayed with 15-25 mg/L 4-Chlorophenoxyacetic acid (4-CPA solution once during the flowering period.
2. 4-Chlorophenoxyacetic acid (4-CPA is used in tobacco to reduce nicotine content.
3. 4-Chlorophenoxyacetic acid (4-CPA is used in ornamental flowers to make flowers grow vigorously, increase new flowers and fruits, and extend the flowering period.
4. 4-Chlorophenoxyacetic acid Acid (4-CPA is used for wheat, corn, rice, beans and other grain crops. It can prevent empty shells. It can achieve full grains, increased fruit setting rate, increased yield, high yield and early maturity.
5. Increase the yield of different vegetables and fruits. For example, the fruit setting rate of tomatoes is improved. Early yield is increased and the harvest period is early. Watermelon is sprayed, the yield is increased, the color is good, the fruit is large, the sugar and vitamin C content is high, and the seeds are less. During the flowering period of watermelon, 20 mg/L of anti-drop solution is sprayed 1 to 2 times, and the 2 times need to be separated. For Chinese cabbage, 25-35 mg/L of 4-Chlorophenoxyacetic acid (4-CPA solution is sprayed in the afternoon on a sunny day 3-15 days before harvest, which can prevent the cabbage from falling off during storage and has a fresh-keeping effect.
6. 4-Chlorophenoxyacetic acid (4-CPA is used to cultivate rootless bean sprouts.
Precautions for using 4-CPA
(1) Stop using it 3 days before harvesting vegetables.
This agent is safer than 2,4-D. It is advisable to use a small sprayer to spray flowers (such as a medical throat sprayer) and avoid spraying on tender branches and new buds. Strictly control the dosage, concentration and application period to prevent drug damage.
(2) Avoid applying on hot and sunny days or rainy days to prevent drug damage.
This agent cannot be used on vegetables for seed.
