Products Applications
1. Used as plant growth regulator, fruit drop preventer, herbicide, can be used for tomato flower thinning, peach fruit thinning
2. Plant growth hormone, used as growth regulator, fruit drop preventer, herbicide, can be used for tomatoes, vegetables, peach trees, etc. 4-Chlorophenoxyacetic acid is a phenoxy plant growth regulator with auxin activity, mainly used to prevent flower and fruit drop, inhibit legume rooting, promote fruit setting, induce seedless fruit, and has the effect of ripening and growth.
Precautions
1. Stop using it 3 days before the harvest of vegetables. Using this agent is safer than using 2,4-D. It is advisable to use a small sprayer to spray flowers, and avoid spraying on tender branches and new shoots.

4-CPA-NA is a widely used growth regulator in the production of fruit trees and vegetables. It is also called Fengshouling. Its main function is to increase the fruit setting rate of crops and promote the growth and development of young fruits. It is mostly used in melon and vegetable crops such as eggplant, pepper, tomato, cucumber, and watermelon. 4-CPA-NA belongs to the auxin class, which can promote growth, prevent the formation of abscission layer, and promote fruit setting. 4-CPA-NA has the effect of inducing parthenocarpy. After application, it is safer than 2,4-D and is not easy to cause pesticide damage. 4-CPA-NA is a phenoxy plant growth regulator with auxin activity, which is absorbed by the roots, stems, leaves, flowers and fruits of plants. It prevents tomatoes and other solanaceous vegetables from dropping flowers and fruits, inhibits the rooting of beans, promotes fruit development, forms seedless fruits, matures early, increases yield, and improves quality. Prevent flower and fruit drop, inhibit rooting of beans, promote fruit setting, induce seedless fruit, and accelerate ripening and increase yield. The problem of flower and fruit drop in melon and fruit crops can be solved by spraying or dipping 4-CPA-NA in production.
