For Ontario apple and pear growers, the annual challenge remains the same: how do you maximize the quality and marketability of your fruit while managing labour costs and unpredictable growing conditions? The answer lies in precision fruitlet thinning—and a new option, BREVIS™ 150 SC Fruitlet Thinner, is changing the game.
 

Trusted in global orchards, proven in Canadian conditions.

BREVIS™ 150 SC, a plant growth regulator from ADAMA Agricultural Solutions, has been proven in orchards worldwide and is now making its mark in Canada. Unlike traditional insecticide-based thinning products, BREVIS™ uses a different approach, powered by the active ingredient Metamitron.

BREVIS™ works by creating an effect similar to shading, causing a temporary reduction in carbohydrate production in the tree. This triggers the natural drop of fruitlets, particularly the smaller lateral fruit while tending to preserve the dominant "king fruit"—the strongest, best-positioned apple on each cluster. The result isn't just fewer apples; it's better apples.

Real results that you can measure. 

Trials conducted at the University of Guelph Simcoe Research Station, Ontario, in 2023 demonstrate the measurable impact of BREVIS™ on Gala apples. When compared to untreated controls and grower standard practices, BREVIS™ at 2.3 L/ha delivered notable improvements in the metrics that matter at market: 

•   Increased average fruit diameter, producing larger, more uniform apples

•   Reduced fruit load per subplot, allowing the tree to focus energy on quality over quantity

•   Significantly improved colour rating, with fruit scoring higher on the 0-5 scale

By directing the tree's energy into fewer, better-positioned fruit, BREVIS™ supports the size, uniformity, and market-driven quality characteristics that command premium prices at harvest.

BreviSmart™: A smarter way to apply BREVIS™. 

One of the key advantages of BREVIS™ is application flexibility, which is crucial given Ontario's variable spring weather. To help growers optimize their timing and application rates, ADAMA has developed BreviSmart™, a complementary web-based support tool.

BreviSmart™ takes into account recent environmental conditions, plus those forecast for the near future, to predict the carbohydrate status of the trees in a chosen location, and provides suggestions for rate adjustments. This science-backed approach gives you confidence to use BREVIS™ 150 SC over a range of climatic conditions. 

Reducing Labour Pressure

Beyond fruit quality improvements, BREVIS™ addresses another critical challenge: labour. Effective chemical thinning significantly reduces the need for hand-thinning crews, easing the pressure during an already demanding season. For operations struggling to secure reliable seasonal labour, reducing this pressure can be as valuable as the quality improvements.
 

The Bottom Line

BREVIS™ 150 SC isn't simply about reducing fruit load—it's about growing more profitable fruit. In an industry where margins are tight and market demands for quality continue to rise, precision tools that deliver measurable improvements in fruit size, colour, and uniformity offer a clear competitive advantage.
