Plant Growth Regulator 4-Chlorophenoxy Acetic Acid 4-CPA PCPA 4CPA CAS 122-88-3 White Powder
4-CPA is absorbed by plant via root, stem, leaf, bloom and fruit, It is used to prevent abscission of bloom and fruit, inhibit rooting of beans, promote fruit set, induce ormation of seedless fruit. Also used for ripening and fruit thinning. It performs better when used in combination with 0.1% monopotassium phosphate. It also has herbicidal effect at high dosage.

Function and characteristics
1. Prevent falling of fruits and flower
2. Produce the seedless fruit
3. Increase the percentage of the fruit bearing(increase output) and promote the enlargement of fruit
Doage :
- To used on tomato, when there is 3-4 flower, to usd 20-40ppm 4-CPA to spray the flower tassels, it can increase fruit-seting ratio, and lead fruit go to market earlier .
- Eggplant: to use 10-20 ppm spray flower, it can reduce flower falling. Increase fruit setting ratio, and increase output.
- To used on grape: before the full flower period 5day, to use 15 ppm spray. Increase output.
