This clean plant center for berries was initiated in collaboration with Oregon State University in the 1960s and fully managed by USDA-ARS as part of the small fruit virology program since 1997. The program works with breeders and nurseries to develop strawberry, blackberry, raspberry and blueberry plants free of targeted
pathogens. The program uses thermal and chemotherapy to eliminate pathogens from plants and indexes plants using bioassays and laboratory based assays. The program in Corvallis is also involved in developing and
implementing new diagnostic assays for pathogens of these crops to improve the quality of the plants produced.
