Abstract

Two bioassays were performed in order to understand the effect of various picloram concentration on algal growth. In the first bioassay Selenastrum capricornutum was used as the test organism and in the second bioassay a community algal culture isolated from Grant Creek, a Clark Fork River tributary, was treated. In both cases, as the concentration of picloram approached 100 ppm a definite decline in algal growth was observed.
