Hi, I'm Pinney from PINSOA. Let me guide you through this Products page.
Our company has been working on the development of catalysts and plant regulators for over 12 years. Click the button below to learn more about our product: its uses advantages, parameters, and dosage, how to buy, etc.
Functions
1.4-CPA is a systemic, highly efficient, and multifunctional plant growth regulator that can prevent flower and fruit drop, inhibit rooting of beans, promote fruit setting, induce seedless fruit, and accelerate ripening and growth.
2. Used as a plant growth regulator to improve plant quality
3. It has the effect of a herbicide. It is mainly used in tomatoes, grapes, vegetables, etc. It can improve the yield and quality of crops and has great practical value.
4. Enhance storage resistance


How to use
1) Preventing flowers and fruits from falling off: ① At around 9 am, dip the open female flowers of zucchini with 30-40 mg/kg of the solution. ② Put 30-50 mg/kg of the solution in a small bowl and dip the flowers of eggplant in the morning on the day of flowering. ③ Spray the flowering inflorescences of kidney beans with 1-5 mg/kg of the solution, once every 10 days, and spray twice in a row. ④ During the flowering period of autumn cowpea, spray the flowers with 4-5 mg/kg of the solution, once every 4-5 days. ⑤ When 2/3 of the flowers on each inflorescence of tomatoes are open, spray the flowers with 20-30 mg/kg of the solution. ⑥ During the flowering period of grapes, spray with 25-30 mg/kg of the solution. ⑦ When the female flowers of cucumbers bloom, spray the flowers with 25-40 mg/kg of liquid medicine. ⑧ Three days after the sweet (hot) peppers bloom, spray the flowers with 30-50 mg/kg of liquid medicine. ⑨ During the flowering period of the female flowers of winter melons, spray the flowers with 60-80 mg/kg of liquid medicine.
(2) Enhance storage resistance: 3-10 days before the Chinese cabbage is harvested, choose a sunny afternoon and spray the cabbage from the base to the top with 40-100 mg/kg of liquid medicine. It is best to moisten the leaves without dripping.


Precautions
(1) Parachlorophenoxyacetic acid works best as a fruit-setting agent when there is sufficient water and fertilizer and the plant grows vigorously. It is best to add some trace elements when using it, but the ratio varies for different crops, so do not use it indiscriminately.
(2) Grapes are sensitive to parachlorophenoxyacetic acid, so do not spray it on the leaves.
(3) Use it before 10 a.m. or after 4 p.m. on the second day after the crop blooms.
(4) Strictly control the concentration of use and do not increase the concentration at will. After mixing the powder with water, stir it thoroughly for 2 minutes before use.
(5) The spraying site is the pedicel and young fruit of the crop. Do not spray it on the growth point or young leaves. If you accidentally spray it on young leaves and severe leaf curling occurs, you can spray 1g of 90% gibberellin with 45kg of water, and it will get better after a few days.
