New Fungicide Increases Sellable Yields

California strawberry and lettuce growers can now get more harvest to market—and onto kitchen tables—with the recent state registration of KENJA® 400SC fungicide from SummitAgro USA.

The group 7 fungicide provides a new and powerful weapon against botrytis gray mold in strawberries and Sclerotinia drop in lettuce, both serious diseases which can devastate yields.

“KENJA’s chemistry—the actual molecule—is different,” says Jim Sturges, SummitAgro Regional Manager. “A 4th generation SDHI fungicide, not only does KENJA provide exceptional in-season disease protection it’s unique chemistry helps to minimize SDHI resistance potential.

In strawberries along with great Botrytis control the really big deal is that when applied as last spray before harvest, KENJA can add days to post-harvest shelf life, so growers can get more high quality fruit to market.  KENJA is also active on other key strawberry diseases, including powdery mildew and anthracnose.  

In either direct seeded or transplanted lettuce KENJA provides highly effective control of Sclerotinia drop (Sclerotinia sclerotiorum and Sclerotinia minor) and can easily mesh with current disease management programs.  The product label provides specific use instructions for both crops.

“Strawberry and lettuce growers face tough challenges – not just up to harvest, but all the way to market,” says Sturges. “SummitAgro is proud to provide a new product for these high value growers, so they can see higher quality and sales, while managing resistance and safety.”
