Introducing a New Era of Nematode Resistance Coupled with Market-Leading Qualities
The vegetable seeds business by BASF, operating in the market under the Nunhems® brand, proudly announces the launch of the Percyst® brand of carrots, a groundbreaking carrot variety that boasts more than 20 years of dedicated research and innovation. The Percyst brand of carrots is not only the first carrot variety featuring intermediate resistance to Southern root-knot and root-knot nematodes1, but it also showcases market-leading qualities in flavor, color and texture, setting a new standard for carrot cultivation.
Nematodes, particularly Southern root-knotand other root-knot species, are notorious for reducing carrot yield and quality, causing an estimated $10 billion in crop damage annually in the United States2, furthermore research conducted in 2023 by the U.S. Department of Agriculture’s Agricultural Research Service shows nematodes have created significant economic and cultivation challenges for growers, particularly in California. Percyst carrots bring a unique solution to the nematode problem: it is a nematode-resistant seed variety, engineered to reduce reliance on chemical fumigation, the traditional method of nematode management. This is especially critical in California, where regulations on chemical use3 demand resilient solutions.
BASF | Nunhems has a longstanding history of developing state-of-the-art seed solutions that have redefined possibilities for fruit and vegetable growers worldwide. From hybrid tomatoes with high yield potential and cucumbers with enhanced disease resistance, to melons bred for enhanced flavor and onions designed for greater uniformity, every breakthrough has been guided by the same principle: supporting growers with innovations that anticipate their needs. The launch of Percyst carrots carries this legacy forward, delivering a resilient carrot variety designed to help tackle one of agriculture’s most persistent challenges."
"Our journey with Percyst brand carrots reflects the team’s strategic foresight and dedication to addressing long-standing grower challenges," said Kaitlyn O’Neal, BASF | Nunhems Regional Crop Lead, Americas: Carrot, Onion. "This variety not only leverages advanced resistance traits but also delivers the consistency and resilience growers need to remain competitive in an evolving market."
Beyond its resistance capabilities, Percyst carrots excel with their dual-purpose versatility, suitable for fresh market cellos and processing into baby carrots. This adaptability offers growers flexible opportunities across multiple market segments.
Percyst brand carrots will be available this planting season through authorized BASF | Nunhems distributors.
