Looking for viruses in all the right places: new vectors and viruses in small fruit crops. Phytopathology. 2004. v94 p. S137. Interpretive Summary: Technical Abstract: During the last 15 years, a number of new and reemerging virus diseases have become important constraints in production of small fruit crops in North America. Pollen- and aphid-borne viruses have become important factors in blueberry, raspberry, and strawberry production. Concentrated production and planting of susceptible cultivars has led Raspberry bushy dwarf virus to reemerge as a serious disease in Rubus species worldwide. In strawberry, some aphid-borne viruses have expanded their geographical ranges. The expansion is not due to a change in the range of the vector, but rather a change in virus-vector relations. In strawberry and blackberry, the naturalization of the greenhouse whitefly, Trialeuroides vaporariorum, and possibly other whiteflies in the southern regions of the USA has resulted in the widespread appearance of several new criniviruses as well as Beet pseudo-yellows virus. A complex pattern of plant production and movement also contributes to the increase in virus and phytoplasma diseases in production fields. The detection and impact of these viruses, along with the occurrence of viruses new to the USA will be discussed. |
