Bayer Ethrel - Plant Growth Regulator

Ethrel by Bayer is a plant growth regulator (PGR) containing Ethephon (39% SL) that promotes uniform fruit ripening, improves coloration, induces flowering, and helps break alternate bearing in crops like mango, pineapple, tomato, coffee, and rubber by releasing ethylene within plant tissues. It's a systemic, water-soluble liquid used to optimize harvest quality and yield, with applications including mango (breaking alternate bearing), pineapple (uniform flowering), and coffee (ripening). 

Key Functions

• Ripening & Coloration: Accelerates and standardizes ripening and color development in fruits.

• Flowering: Induces profuse flowering, especially in mangoes.

• Yield Improvement: Breaks alternate bearing cycles in mangoes, ensuring consistent yields.

• Defoliation: Used in pomegranate for synchronized fruit development.

• Latex Yield: Promotes latex flow in rubber trees. 

How It Works

• Ethrel is absorbed by plant tissues and gradually breaks down to release ethylene, a natural plant hormone.

• This ethylene then influences various growth processes, leading to the desired effects like uniform ripening and flowering. 

Common Applications by Crop

• Mango: Breaking alternate bearing & inducing flowering.

• Pineapple: Inducing uniform flowering.

• Tomato: Improving color and uniform ripening (including post-harvest).

• Coffee: Ensuring uniform berry ripening.

• Rubber: Enhancing latex yield.
