Interpretive Summary:

Technical Abstract: In the 2002 and 2003 growing seasons, strawberry plants in coastal California and British Columbia developed symptoms of leaf reddening, stunting, and plant death. Up to five viruses were identified in declining plants in these areas. In CA, the majority of the plants (75%) were infected with Strawberry pallidosis associated and Beet pseudo-yellows viruses, the two criniviruses that infect strawberry. While the aphid-borne viruses, Strawberry mild yellow edge(SMYEV), Strawberry mottle (SMoV) and Strawberry crinkle(SCV) viruses were found in 20-25% of the plants. Two viruses, Strawberry latent ringspot and Fragaria chiloensis latent viruses, not known to occur in the U.S. and Canada were identified in CA and B.C. In B.C., the majority of the plants (close to 100%) were found to be infected with SMYEV and SMoV, about 25% with SCV, and none with the whitefly transmitted viruses. Further investigations are under way to determine whether or not the individual viruses play a role in the decline problem.
