CybeRelease: (OTC PK: PSVI) New Product Kills Citrus Disease

(CybeRelease, December 15, 2006) - Lake Harmony, PA - Preservation Sciences, Inc. (OTC PK: PSVI), discovering new technologies through natural resources, announced today that an independent scientific study has demonstrated that its agricultural antimicrobial product Canker Kill(TM) successfully killed virtually all of the bacteria that causes citrus canker, a devastating tree disease responsible for billions of dollars in damages to the world’s orange juice and citrus trees, among other important crops.

The U.S. Department of Agriculture recently granted technical clearance for experimental use of Canker Kill in treatment of citrus canker. An independent lab, ABC Research in Gainesville, Florida, conducted controlled multi-lab tests of Canker Kill(TM), generating new data demonstrating the effectiveness of the Preservation Sciences antimicrobial product.

The experiments showed near-total suppression of the Xanthomonas bacteria, which is responsible for the citrus canker that has caused billions of dollars in damages to the nation’s citrus crops. In the tests, Preservation Science’s patent-pending Canker Kill(TM) product was effective at killing 99.995 percent of the canker bacteria, with a 98.84 percent reduction of mean canker counts following a five-minute exposure time.
