Ethephon 39 SL (39% w/w)

Ethrel is a versatile plant growth regulator which improves colouration and accelerates uniform ripening of fruits like pineapple, mango, tomato, etc. It can be deployed in specific uses like defoliation in pomegranate and breaking alternate bearing in mango.


Ethrel is plant growth regulator with systemic properties. It penetrates into the plant tissues, and is translocated and progressively decomposed to ethylene, which positively affects the growth process.
