Abstract

The absorption and translocation of labeled herbicides by submersed weeds was studied by sealing the immersed root system in a 60 ml polyethylene bottle and immersing the bottle and shoots in water in a 500 ml graduate. The medium for either roots or tops could be treated without affecting the other. Simazine [2-chloro-4,6-bis(ethylamino-1-C14)-s-triazine] and fenac [2, 3, 6-trichlorophenylacetic acid-1-C14 (mixed isomers)] were absorbed by both roots and shoots of waterstargrass (Heteranthera dubia) and translocated to the untreated portion (root or shoot) of the plant. The distribution patterns of C14-labeled simazine and fenac in bluegills (Lepomis macrohirus) were studied by gross autoradiography. The viscera of the fish contained the greatest amount of activity.
