Detailed Introduction about CPPU

- Jul 05, 2018 -

Forchlorfenuron (KT-30) can be absorbed through the plant's roots, stems, leaves, flowers, and fruits, and then transported to the site of action. The main physiological role is to promote cell division, increase cell number, increase fruit; promote tissue differentiation and development; break lateral bud dormancy, promote germination; delay aging and regulate nutrient distribution; improve pollen fertility, induce parthenocarpy of fruit trees, Promote fruit setting and improve fruit quality. Forchlorfenuron (KT-30) is a synthetic kinetin that promotes cell division activity. Its biological activity is about 10 times that of 6-BA.


Main function of CPPU: 

Forchlorfenuron (KT-30) is a broad-spectrum and versatile plant growth regulator. At a concentration of 1 mg/L, it induces callus growth of various crops. The fruit was sprayed at 20 mg/L for 30 days after flowering to increase the fruit size, promote coloration and improve quality, and expand the application period of gibberellic acid (GA3). Forchlorfenuron was 1-5 mg/L at 14-18 d before flowering. + GA3 100mg/L soaking fruit, increase the effect of GA3

◆ Expanded fruit, improve quality

◆ Promote fruit setting and increase yield

◆Prevent the degradation of chlorophyll and extend the freshness of fresh products



(1) Forchlorfenuron is used as a fruit setting, mainly for flower and fruit processing. It should be used with caution in melons and watermelons, especially when the concentration is high. Increasing the grain weight of wheat and rice is also mainly from the top down spraying of wheat and the top of the rice plant.

(2) The combination of Forchlorfenuron and gibberellic acid or other auxin is superior to single use, but it must be performed under the guidance of professionals or after the demonstration of the first test, do not mix them arbitrarily.

(3) Reapply if it rains 12-24h after treatment.
