AgraQuest's biofungicide, Serenade, was granted registration by the U.S. Environmental Protection Agency for four more uses. Serenade(R) can now be used on blueberries, greenhouse vegetables, green beans and mint, in addition to the already registered uses on vines, melons, squash, hops, peanuts, leafy vegetables, potatoes, peppers, tomatoes, cherries, apples, pears and walnuts. "AgraQuest is excited to offer new disease management technology to more producers," says Jim Chambers, Director of Sales and Marketing, "especially since they are losing traditional tools due to the restrictions imposed by implementation of the Food Quality Protection Act."

Serenade(R) is a natural fungicide containing a strain of Bacillus subtilis that has shown to control many plant pathogens including Botrytis Gray Mold, Bunch Rot, Sour Rot, Powdery Mildew, Fire Blight, and Bacterial Spot. Serenade utilizes multiple modes of action preventing pathogens from attacking prior to infection, preventing spores from developing at the time of infection and attacking and destroying pathogens during an infection. The multiple modes of action make it difficult for pathogens to develop resistance to Serenade, and therefore, it is a powerful tool when used in a program with chemical fungicides that are more susceptible to resistance development.

Serenade has been listed by the Organic Materials Review Institute and is non-toxic and safe in the environment. With the issuance of the new patent, AgraQuest now has four U.S. patents supporting its product Serenade. AgraQuest now has 20 U.S. patents, 9 foreign patents and has filed an additional three on an exciting new fungicide, a bioinsecticide and a biofumigant.

Due to the potential of international markets for Serenade, AgraQuest recently hired Humberto Alba as Director of International Business. Mr. Alba was most recently at Syngenta Seeds as President and General Manager of Korea. He also worked at Valent USA, Mycogen and Monsanto in senior international positions. Mr. Alba has a BS in Agronomy and Horticulture from Brigham Young University.
