Certis to Launch New Biofungicide Formulation

1/5/2013 7:00 AM

COLUMBIA, Md. — Certis USA LLC has announced that it has entered into an agreement with Kaken Pharmaceutical Co. Ltd. of Tokyo, Japan, to introduce a new polyoxin D zinc salt formulation to the U.S. market under two trade names — TAVANO 5%SC Fungicide for use on grapes and small fruits including strawberries, and OSO 5%SC Fungicide for use on citrus, cucurbits, fruiting and leafy vegetables, potatoes, and numerous other crops.

Polyoxin D zinc salt was first registered for food use in the U.S. in late 2008. The U.S. Environmental Protection Agency has recently expanded the tolerance exemption to include its residues in all food commodities. It also has approved the registration of a new 5 percent suspension concentrate formulation.

Polyoxin D zinc salt is a broad-spectrum fungicide used against Alternaria leaf blight and early blight, Botrytis, powdery mildew and other diseases. It is derived through the fermentation of a naturally occurring microbe, Streptomyces cacaoi var. asoensis, which was isolated from soil in Japan.

The biochemical active ingredient controls pathogenic plant fungi by inhibiting the formation of chitin, a component of fungal cell walls. This nontoxic mode of action allows polyoxin D zinc salt to be used in rotation with other fungicides for resistance management within Integrated Pest Management programs.

Headquartered in Columbia, Md., Certis USA is a manufacturer and distributor of a broad line of biopesticide products.
