Preferal Biological Insecticide registered in California

Date:08-10-2012

SePro Corp.'s new Preferal biological insecticide is now registered in California for us in the greenhouse, nursery and landscape markets.

Preferal is a biological insecticide containing blastospores of a naturally-occurring strain of the fungus Isaria fumosoroseus which has demonstrated very good control of whitefly, aphid, thrips and spider mites.  Isaria fumosoroseus was isolated by Dr. Lance S. Osborne, with the University of Florida.  Certis USA, which licensed the technology from the University of Florida, has entered into a marketing and supply agreement with SePRO to market and further develop Isaria fumosoroseus in the U.S. greenhouse, nursery, landscape and turf markets. 

Preferal is formulated as a water dispersible granule that is mixed with water and applied as a spray.  Spores of Preferal then attach and penetrate the cuticle of targeted insect pests.  The fungus grows inside the insect, causing its death.  Under favorable environmental conditions, the fungus will emerge from killed insects to re-release more viable spores to sustain further infections in other insects.
