Walnut Creek, California (January 31, 2018)--Valent U.S.A. LLC today announced the label expansion for ReTain® Plant Growth Regulator for California Soluble Powder to include aerial application for almond bloom. This new use provides growers and workers with application flexibility during a tight almond bloom window.
ReTain extends the viability of almond blooms and offers more opportunity for flowers to be pollinated, which greatly improves nut set and yield potential. In aerial application trials conducted in 2016 and 2017 with ReTain on nonpareil almonds, nutmeat yields increased by 312 pounds — or a 12.2 percent yield increase — over the untreated check. Applications were made via fixed-wing or rotary-wing aircraft at application volumes ranging from 15 to 20 gallons per acre.
"Time is critical for growers at bloom," said Tom Caruso, Tree Nut Crop Marketing Manager for Valent. "ReTain has proven to be the trusted technology for almonds; and with aerial application, growers are able to reach more orchard blocks much faster and more effectively in order to boost nut set and yield potential."
ReTain works by reducing ethylene production in almond flowers and delaying flower and stigmatic senescence. This results in flowers being viable longer, which allows more time for pollination to occur. Field studies have demonstrated that ReTain extends the life of an almond bloom by 43 percent over the untreated check.
ReTain can be applied between 10 percent and full bloom; however, the recommended application timing is between 30 to 60 percent bloom, and the aerial application allows growers to pinpoint that optimal timing for best results. ReTain offers an easy-to-use rate of one water soluble pouch per acre. In addition to aerial applications, ReTain can also be applied by ground, via air blast sprayer at the recommended spray volume of 100 to 200 gallons per acre.
