| Abstract: | A virus disease of cowpea widespread in North Italy has been found to be caused by a virus which has the following properties: a. rod-shaped particles about 750 mµ in length; b. serological affinity with bean common mosaic virus; c. aphid-transmission; d. seed-transmission in cowpea at a percentage of 0.3–1.59; e. fairly wide host range covering 19 species representing 13 genera and 6 families; f. dilution end-point 1:4000; g. thermal inactivation point 60–62°C; h. longevity in vitro 5 days. The virus is tentatively called “cowpea aphid-borne mosaic virus”. |
