- ReTain is the premier harvest management tool on the market, extending harvest time and allowing growers to harvest with fewer pickers, while the fruit matures to optimal size, color, and condition. Applying ReTain four weeks before apple or pear harvest provides maximum protection against accelerated fruit drop, especially valuable when unfavorable weather such as high wind, excessive heat, or drought occurs prior to harvest. Slowing drop also allows apples to reach their maximum size. Additionally, ReTain reduces watercore and stem bowl cracking, ensuring improved packout and fruit quality. ReTain slows the maturation process, helping more fruit to have optimum quality going into and coming out of storage.
- ReTain affects different cultivars, often raised under different growing conditions, in slightly varied ways. Valent BioSciences Corporation offers detailed production guidelines for ReTain use for each crop type and situation.
- In walnuts, ReTain blocks the production of ethylene as well. That’s helpful because ethylene causes Pistillate Flower Abscission (PFA) during bloom – a condition that can lead to reduced fruit set and low yields. ReTain consistently increases yield in walnut orchards that suffer from low nut set due to PFA.
- In stone fruit, ReTain applied a few weeks prior to harvest can improve harvest management by allowing peaches and nectarines to develop excellent flavor without becoming soft and dropping prematurely. Slowing drop also allows stone fruit to continue to increase in size. In varieties prone to soft tip, ReTain applied two weeks prior to harvest can help reduce the condition.
- Benefits
When you apply ReTain® four weeks before harvest, your apple crop benefits in several ways:
• More flexible harvest management
• Reduced fruit drop
• Maximized fruit size
• Improved fruit quality and color
• Reduced physiological defects
• Improved post-harvest value

Technical Details & Test Data
- Optimize Harvest Management with ReTain®
By extending the harvest time, ReTain® Plant Growth Regulator allows growers to reduce the total number of pickers. For example, by picking the untreated block in one week and the ReTain®-treated block the next week, this grower was able to reduce the number of pickers by nearly half over the same area and was better able to manage operations over this extended harvest period.

ReTain® Improves Fruit Quality and ColorMaintain Fruit Firmness with ReTain
ReTain® improves fruit quality by maintaining fruit firmness and also enhances storage and market shelf life potential.

Improve Red Color with ReTain® (Indirect)
ReTain® delays fruit maturation, which allows for longer hanging time and potentially more favorable weather conditions to improve color development.
