A survey of virus diseases of soybean (Glycine max (L.) Merr.), mung bean (Vigna radiata (L.) Wilczek), and peanut (Arachis hypogaea L.) was undertaken in East Java, Indonesia. Leaf samples were collected from eight different locations and tested by DAS-ELISA for presence of peanut stripe (PSt V), alfalfa mosaic, adzuki bean mosaic (AzMV), bean common mosaic (BCMV), blackeye cowpea mosaic (BICMV), bean yellow mosaic (BYMV), peanut mottle, soybean stunt, soybean mosaic, cowpea mosaic, cowpea mottle, peanut stunt, blackgram mottle, southern bean mosaic, and cucumber mosaic (CMV) viruses. In soybean, the incidence of BYMV was highest, with 81% of 103 samples infected with the virus. This was followed by AzMV and CMV (both 60%). BCMV was found in 23%, PStV in 6%, and BICMV in 1% ofthe samples. In mung bean, 95% ofthe samples contained BYMV, followed by AzMV (76%), PStV (60%), BICMV (48%), BCMV (44%), and CMV (12%). In peanut, 24% were infected with AzMV, followed by BYMV (22%), BICMV (18%), CMV (16%), and PStV (15%). Virus infections were mixed in 77, 92, and 94% of peanut, mung bean, and soybean samples, respectively. In East Java, BYMV and AzMV are widely distributed in all three crops. Mung bean appears to be a newly recorded natural host of PStV.
