ReTain Plant Growth Regulator. Harvest the Potential.

ReTain is the foundation of successful harvest management and post-harvest quality programs for apples and pears. ReTain is now registered for up to two applications prior to harvest. With up to two applications per acre per season, ReTain creates an extended harvest management period and opportunity for more marketable fruit.

ReTain naturally inhibits biosynthesis of ethylene—a plant hormone that affects fruit maturation, ripening, drop and other processes. By inhibiting ethylene, ReTain:

  • Extends the harvest window
  • Provides more flexible labor management
  • Extends drop control
  • Maintains late-season fruit quality

Additionally, ReTain extends flower viability in cherries. This increases the opportunity for fruit to set. ReTain is effective on low set varieties such as Chelan, Regina and more.
