Abstract
The absorption, translocation and metabolism of 14C-profluralin and 14C-dinitramine in sorghum 'RS6-12', Echinochloa crus-galli, soybean cv. 'Dare', and Amaranthus palmeri were determined after treatment with the 14C-labelled herbicides in nutrient solution for 24 h at 16 deg or 38 deg C. 14C-profluralin accumulated in roots to a greater extent at 16 deg C, while metabolism was greatest at 38 deg C. Very little 14C-profluralin was translocated to the tops of plants. Conversely, 14C-dinitramine accumulated in the tops of plants to a greater extent at 38 deg C. Metabolism was not greatly affected by temperature. These effects may relate to excess toxicity of profluralin at 16 deg C and dinitramine at 38 deg C in species which normally exhibit resistance to the herbicides. From summary
