QualiPro Ethephon 2SL: Plant Growth Regulator


Description

Ethephon 2SL is a plant growth regulator formulated with ethephon (2-chloroethylphosphonic acid) as the active ingredient. It is used to enhance fruit ripening, induce flowering, reduce lodging in cereals, promote uniform harvest, and regulate growth in various crops. When applied, ethephon is absorbed by plant tissues and converted into ethylene, a natural plant hormone that influences growth and development.


Key Benefits

  • Promotes uniform fruit ripening in crops like tomatoes, apples, and pineapples.

  • Enhances harvest efficiency by inducing early and even ripening in crops such as cotton and coffee.

  • Reduces lodging in cereals like wheat and rice by strengthening plant structure.

  • Stimulates flowering in crops like pineapples to synchronize production.

  • Inhibits shoot growth in ornamentals and turfgrass for better plant management.

Application Rates

  • Rate: 5 fl. oz. per 1,000 sq. ft.

  • Frequency: 

    • Poa annua and White Clover Seedhead Suppression: 2 weeks or greater for all labeled grasses.

    • Turfgrass Growth Regulation:

      • Kentucky Bluegrass & Perennial Ryegrass: 7 Weeks

Always refer to the product label for crop-specific rates, timing, and application methods.
