ReTain® Plant Growth Regulator for California

PGRs and Protectants


Extend Bloom. Increase Nut & Fruit Set.

ReTain® PGR for CA increases nut & fruit set in almonds, walnuts & cherries to optimize crop load potential. ReTain works by reducing ethylene production in blooms—delaying flower and stigmatic senescence. This results in flowers being viable longer, which allows more time for pollination to occur.

ReTain® Plant Growth Regulator for California increases nut and fruit set in almonds, walnuts and cherries to help ensure an optimum crop load potential. The naturally occurring active ingredient in ReTain works by reducing ethylene production in blooms thus delaying flower and stigmatic senescence. This effect results in flowers being viable longer, which allows more time for pollination to occur.

In addition, ReTain consistently increases nut set in walnut orchards that suffer from low nut set due to Pistillate Flower Abscission (PFA).
