Johnson grass (Sorghum halepense L. Pers.1, a severe weed pest in the southeastern Lnited Stntes, has been shown by several workers to release compounds toxic to higher plants. Here, several previoul) isolated phytotoxins and taxiphyllin, not previously found in Johnson grass, have been isolated from methanolic extracts of Johnson grw rhizomes. These ccimpounds were active against tomato and radish seedling root growth and alao inhibited growth of several of nine bacteria tested. Exudates from living rhizomes did not affect radish and tomato root grc~wth but did affect bacterial growth and slowed germination of three of five crop species tested. A I3C NMR method ie presented for distinguishing the epimers dhurrin and taxiphyllin which were found in Johnson grasv rhizomes
