Abstract

Results of a survey for the presence of tobacco-mosaic and pepper-mosaic viruses in the Filler-Tobacco Area of Puerto Rico, indicate that tobacco mosaic was the most prevalent, being present in a total of 75.4 percent of tobacco samples tested. Pepper-mosaic virus was found present in 17 percent of all samples tested. These results were obtained by employing both the usual infectivity (plant-host) method and precipitin tests. Complete correlation was not observed between the two kinds of tests, however and the results show that a larger number of positives is obtained by using both tests than by using either test alone.
