Fine Americas announced the federal Section 3 registration of its new Refine™ plant growth regulator. Refine features the active ingredient naphthaleneacetic acid (NAA) and is labeled for use on apples, pears, citrus and olives.
“Refine is a proven plant growth regulator for fruit thinning and control of pre-harvest drop in apples and pears,” explained Greg Johnson, president of Fine Americas. “In both crops, it serves as an effective chemical thinning agent for reducing fruit set during heavy-bearing years while promoting increased fruit size. In addition, a late-season application of Refine (7 to 14 days prior to harvest) can lead to higher yields by reducing losses caused by premature fruit drop from windfall and knockdown.” He added that Refine also is registered for thinning in certain citrus crops (oranges, tangerines, mandarins, tangelos and tangors), as well as olives.
Jim Scruggs, technical services manager for Fine, noted that “Refine also can be used to promote return bloom in apples during ‘off years’, especially in certain alternate-bearing varieties such as Fuji, Jonagold, Mutsu, Braeburn and Golden Delicious. This feature allows apple growers to meet market demands on a more consistent basis.”
