Severe outbreaks of tomato shoestring, varying in incidence from 5 to 42%, occurred in commercial tomato plantings in Chile. The causal agent was identified as tomato mosaic virus based on biological, physical, morphological, and serologic properties. Cucumber mosaic virus was not found in any of five field samples assayed.
