*.Max. application rate per season 2.18 kg/ha for cotton, 0.72 kg/ha for cereals, 1.44 kg/ha for fruit.
Accelerating ripening and maturation of fruits by releasing ethylene. Fruits treated with ethephon showed rapid increase in respiratory rate.
The most suitable period is when the fruit begin to mature, when colored fruits begin to color, white fruits slightly turn yellow, then you would get the best effects.

- Promote plant organ aging mature. Such as for ripening of cottonball , tomatoes turning red.
- Restrain stem and leaves growth, such as for maize dwarf and lodging-resistance, cultivate stocky rice seedling, control lychee tip to promote ear.
- Increase numbers of female flower of cucumbers and improve output.
- Break the dormancy and promote seed germination.√ Stimulate rubber run latex, improve production
- Promote shedding fruit of hawthorn, dates, easy picking fruit.
- For wheat male sterility , promote dwarf plant and good plant shape
- Cuttage rooting and inducing plants roots
- Promote pineapple flowering, shorten the growth time of pineapple

- Ethephon plant growth hormone 40%SL 85%TC : Ethephon, an organic compound, pure white needle crystal, industrial product is light brown liquid, soluble in water, methanol, acetone, ethylene glycol, propylene glycol, slightly soluble in toluene, insoluble in petroleum ether. Used as a stimulant for agricultural plant growth.
- Ethephon is a high-quality and high-efficiency plant growth regulator that promotes fruit ripening, stimulates wounds recovery, and regulates gender conversion. Penetrating into the plant by leaves, bark, fruits or seeds, then transmitted to the final destination.
- Ethephon is a kind of high effect plant growth stimulants, promote ripening, widely used to accelerate ripening of fruits, tomato, sugar beet, coffee, etc; to increase the tillering of wheat and rice; to prevent lodging in rice, maize and flax; to accelerate boll opening and defoliation in cotton; to hasten the yellowing of mature tobacco leaves; to stimulate latex flow in rubber trees, and resin flow in pine trees; to stimulate early uniform hull split in walnuts; etc.
