Product List


Introduction to Ga4+7

Mechanism of Action: Gibberellic acid GA4+7 works by promoting cell elongation and division, which leads to increased plant growth and development. It influences various physiological processes including stem elongation, germination, dormancy breaking, flowering, and fruit set.

Usage: GA4+7 is used across a variety of fruit trees, including apples, pears, cherries, and citrus. It helps improve fruit set, reduce premature fruit drop, enhance fruit size, and stimulate flowering. This growth regulator is particularly useful in commercial orchards to optimize yield and quality.


  • Apples and Pears: 10-20 ppm (parts per million) applied during the bloom period to enhance fruit set.
  • Cherries: 20-50 ppm applied at full bloom to reduce fruit drop.
  • Citrus: 10-15 ppm applied during early fruit development to improve fruit size.
