| Abstract: | Tomatillo ( Physalis ixocarpa ) is being evaluated as a food crop in Louisiana. Preliminary studies indicate that virus diseases may be the major factor limiting production. A foliar mosaic and yellow mottle disease was found commonly affecting plants in experimental plots. The cause of the disease was identified as physalis mottle virus (PhyMV). The virus was identified by host reaction, serology and dsRNA analysis. Other viruses found less frequently included cucumber mosaic virus and tomato spotted wilt virus. The flea beetle, Epitrix cucumeris , transmitted PhyMV experimentally. The annual weed Physalis pubescens was found naturally infected with PhyMV near infected tomatillo. |
