Adpon

Adpon (Ethephon 39% SL)


Adpon is a plant growth regulator that releases ethylene, a naturally occurring plant hormone, to regulate plant growth and development. It is formulated as a 39% soluble liquid (SL) and is widely used to promote ripening, enhance fruit quality, and control plant height.

Mode of Action:


Ethephon 39% SL is metabolized into ethylene, which accelerates fruit ripening, promotes abscission (such as fruit drop), and can reduce plant height by inhibiting excessive growth. This action is particularly useful in controlling the timing of harvest and improving crop uniformity, especially in fruits like pineapples and tomatoes.

 

Key features and Benefits:


• Accelerates fruit ripening, allowing for more uniform harvest timing.

• Improves colour, size, and overall quality of fruits like pineapples, tomatoes, and bananas.

• Controls excessive vegetative growth in crops like cotton and tobacco.

• Helps synchronize fruit maturity, reducing harvest labour costs.

• Ensures more consistent fruit development and ripening, improving marketability.
