Freely soluble in water and ethanol, allowing seamless integration into existing spray programs and easy tank-mixing with other agrochemicals.









A: Ethephon 40% is a plant growth regulator that releases ethylene inside the plant. It is primarily used to uniformly ripen fruits (like pineapples, tomatoes, coffee), promote fruit abscission for easier harvesting (in cotton, walnuts), induce flowering, and control plant height in cereals.
A: Yes. Ethephon's activity is influenced by temperature and plant metabolism. We provide specific application timing and dosage recommendations tailored to local climate patterns to ensure reliable and effective results across diverse environments.
A: Absolutely. It is highly effective for:
Coffee & Fruits: Induces uniform ripening, improving yield quality for processing.
Cereals (e.g., wheat): Can be used as a growth regulator to prevent lodging.
Sugarcane: Enhances sucrose accumulation before harvest.
4. Q: How fast does it work, and what is the pre-harvest interval (PHI)?
A: Effects typically become visible within 4-7 days after application. The PHI varies by crop (often 7-14 days). It is crucial to follow the specific label instructions for each crop and region to ensure crop safety and residue compliance.
A: It can be mixed with many commonly used contact pesticides and fungicides. However, it is not compatible with strong alkaline substances (like Bordeaux mixture). We strongly advise conducting a small jar compatibility test before large-scale tank mixing.
A: We provide expert agronomic support tailored to regional crops, growth stages, and climate challenges. Contact our technical team for detailed guidance on dosage, timing, and water quality to maximize results and return on investment in your specific area.
