What is Brevis™

Brevis™ is a crop enhancer that provides consistent fruitlet thinning in apples and pears, increasing the marketability of your fruit while cutting down on hand thinning. Powered by the novel active ingredient Metamitron, Brevis™ offers greater application flexibility, making it the ideal choice for pome fruit growers.

Informations générales

HOW IT WORKS

Brevis™ generates a temporary reduction in carbohydrates for the tree. The resulting competition between fruitlets causes a natural fall of lateral fruits while preserving the dominant and/or king fruit.

RATE DETERMINATION

Rate should be adjusted based on orchard-specific factors including but not limited to:

-Amount of desired fruit thinning
-Cultivar/variety
-Weather conditions
-Tree health
-Overall orchard history

Base rate should be determined based on an orchard’s history of thinning propensity. Use a higher application rate in hard-to-thin orchards. In medium-to-thin orchards, use the mid-range rates and use lower rates in easy-to-thin orchards. A carbohydrate model (BreviSmart) can help applicators make rate adjustments on the day of, based on the carbon status of the tree.
