During the 1987 rainy season, field-grown peanut (Arachis hypogaea L.) in the initial evaluation trial ofthe AICORPO showed stripes, green' blotches, and oakleaf mosaic typical of those caused by peanut stripe virus (PSt V). Mechanically sap-inoculated greenhouse-grown peanut cultivar TMV-2 plants showed symptoms similar to those observed in the field. The virus produced chlorotic local lesions on Chenopodium amaranticolor Coste & Reyn. In the direct antigen coating method of indirect ELISA, the virus reacted positively with PStV and blackeye cowpea mosaic virus antisera and negatively with peanut mottle virus (PMV) and peanut green mosaic virus (PGMV) antisera. The isolate of PStV also differed from PMV and PGMV in host range and symptomatology. Dip preparations of peanut leafsamples stained with I % uranyl acetate showed several flexuous, rod-shaped particles. The disease was observed in plants at six of 12 locations surveyed.
