4-CPA-NA is a phenolic plant growth regulator, which is absorbed into the plant body by the roots, stems, leaves, flowers and fruits of plants. It is mostly used in tomatoes, eggplants, peppers, cucumbers, watermelons, etc. to prevent flowers and fruits from falling, inhibit rooting, etc., and can adjust the balance of hormones in plants, stimulate ovary expansion, and supplement the lack of auxin in plants.

4-CPA-NA can be absorbed by rhizomes, flowers and fruits, and its biological activity lasts for a long time. Use concentration: 5-25ppm is appropriate, 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 a concentration of 25-30 mg/L 4-CPA-NA solution during flowering, 2 times in a row, each time with an interval of 1 week. When tomatoes are halfway through blooming, spray them with 25-30 mg/L 4-CPA-NA solution once. Peppers are sprayed with 15-25 mg/L 4-CPA-NA solution once during the flowering period.

2. Used in tobacco, it can reduce nicotine content.

3. Used for ornamental flowers, it can make the flowers grow vigorously, increase the number of new flowers and fruits, and extend the flowering period.

4. Used for grain crops such as wheat, corn, rice, beans, etc. It can prevent empty shells. Make every grain full, increase the fruit setting rate, increase the yield, and achieve 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 seed is less. During the flowering period of watermelon, 20 mg/L of 4-CPA-NA solution is sprayed 1 to 2 times, and the 2 times need to be separated. For Chinese cabbage, 25-35 mg/L of 4-CPA-NA 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. Used to cultivate rootless bean sprouts.

When spraying flowers, be sure to spray at a fixed point (spray only flowers and not stems and leaves). The spraying time should be selected in the morning or evening on a sunny day. If spraying is done under high temperature, scorching sun or on rainy days, it is easy to cause pesticide damage. After using anti-drop agents on fruit trees, since fruit setting will increase, it is necessary to strengthen fertilizer and water management to make the plants grow strong and prevent premature aging. Kyoho grapes are more sensitive to anti-drop agents, so do not use them for foliar spraying.
