Chlorella elipsoidea assay was investigated to perform comparative activity-tests of herbicides. Chlorella cells have many good characters to fulfil our aims. The cultivation of the cell is possible all the year round, the growth speed is so rapid that the cell numbers become about ten times for 24 hours, and the growth inhibition can be determined colorimetrically. From our results, it may be concluded that this method involves assessment at the 50 percent toxicity level and utilizes certain concepts of probit analysis to herbicides, especially photosynthesis inhibitors.
