| Abstract/Contents: | "The concentration of three sulfonylurea herbicides in soil was determined by a modified petri dish bioassay procedure. The method involved planting pregerminated seed of selected species in petri dishes containing 65 to 100 g of treated soil and measuring the radicle lengths after 24 h. Chlorimuron was detected in two soils at 0.002 ug g-1 using either corn, sorghum, or sicklepod as the assay species. Chlorsulfuron and CGA-131036 were detected in soils at 0.001 ug g-1 using corn, and chlorsulfuron was detected at the same level using sicklepod. In contrast to other methods, the bioassay procedure could be completed in 48 h, including pregermination of the seed, growth of the plants on treated soil, and plant measurements. |
