A simple and sensitive assay system was developed in the search for new herbicidal substances. The system is based on the following two phenomena observed in photosynthesis: (1) de novo starch synthesis, determined in excised leaf segments of barnyard millet (Panicum crus-galli), a C4 plant, and Italian ryegrass (Lolium multiflorum LAM.), a C3 plant; and (2) oxygen evolution in the cells of Scenedesmus obliquus, detected by using an oxygen electrode. The system can detect photosynthesis-inhibiting herbicides at a concentration as low as 0.1 ppm. After assaying 6, 500 microbial culture broths, 6 culture filtrates were selected for further study.
