Wilbur-Ellis recently added Spärra, a unique fungicide-bactericide designed to combat Pythium and other diseases. The fungicide is now labeled for use in California on turf and ornamentals, conifers and other trees.

Wilbur-Ellis said Spärra boasts the highest concentration of EPA-registered potassium phosphite of 59.24 percent mono- and di-potassium salts of phosphorous acid. According to the company, the unique formulation ensures maximum effectiveness against a wide range of fungal and bacterial infections.
