Target Object	promote pre-harvest ripening in apples, tomatoes, coffee, and others, and post-harvest ripening in bananas and mangoes. It aids harvesting by loosening fruits like cherries and apples, prevents lodging in cereals, and improves yields in cotton, cucumbers, and walnuts. It also induces flowering in pineapples and bromeliads, stimulates latex in rubber trees, and enhances sturdiness in onion seed crops.
Mode of Action	Plant growth regulator with systemic properties. Penetrates into the plant tissues, and is decomposed to ethylene, which affects the growth processes

Application Scenarios

FAQ

1. Q: What is the main function of Ethephon 40%?
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.

2. Q: Is this product effective in the variable climates of our regions, from hot deserts to high altitudes?
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.

3. Q: Can it be used on our key crops, such as cotton, coffee, or cereals?
A: Absolutely. It is highly effective for:

Cotton: Promotes boll opening for a synchronized, efficient harvest.
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.

5. Q: Is it safe to mix with other sprays?
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.

6. Q: What specific application advice do you offer for our local conditions?
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.
