To evaluate suitability of the mustard root length inhibition bioassay for detection of pyroxsulam and thiencarbazone residues in soil. To assess the effect of soil properties on phytotoxicity of these two herbicides in different soil types from the Canadian prairies. To study pyroxsulam and thiencarbazone dissipation in soils under laboratory conditions.
This study showed that the mustard root length inhibition bioassay previously reported for flucarbazone detection in soil is suitable for determination of pyroxsulam and thiencarbazone residues and that it can be used for investigation of behavior of these herbicides in soil.
