Frequently Asked Questions

Q: What is Ethephon used for in agriculture?
A: Ethephon is a widely used plant growth regulator. It releases ethylene upon application. Growers mainly use it for cotton defoliation, rubber tree stimulation, sugarcane ripening, and fruit color enhancement. Our Ethephon 40% SL and 480g/L SL are designed for these exact purposes.

Q: How does Ethephon work?
A: Ethephon penetrates plant tissues and slowly decomposes to release ethylene gas. This triggers natural physiological processes like leaf abscission, latex flow, and fruit maturation. The process requires adequate moisture and warm temperatures for optimal results.

Q: What is the difference between Ethephon 40% SL and 480g/L SL?
A: Both contain the same active ingredient, but the concentration differs. Farmers typically choose 40% SL for smaller-scale operations. For large farms and plantations, 480g/L SL works better. It offers a lower per-hectare volume, which cuts shipping costs. Many buyers prefer the high-concentration Ethephon 480g/L SL for sugarcane and rubber programs.

Q: Can I buy Ethephon from China?
A: Yes. As a professional Ethephon manufacturer, Procrochem exports to over 30 countries. We provide full registration support, including GLP reports and 5-batch analysis, to help you clear customs smoothly.

Q: Is Ethephon safe for crops and the environment?
A: When used according to label directions, Ethephon has a good safety profile. It degrades rapidly in soil and water. We recommend adhering to local Ethephon residue limits, especially for export produce bound for the EU market.

Q: How should I store Ethephon formulations?
A: Store Ethephon 40% SL and 480g/L SL in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly sealed. The shelf life is 2 years under proper storage conditions.

Q: Do you offer free samples?
A: Yes, we provide free samples of our Ethephon TC, 40% SL, and 480g/L SL for evaluation. Contact us with your application details, and we will arrange the shipment.
