Abstract
In laboratory studies, an average of 1.5 ppm of diquat remained 65 days after the application of 5 ppm of diquat, and an average of 0.12 ppm remained 28 days after the introduction of 1 ppm of diquat. In fall field studies 0.32 ppm of diquat remained 24 hours after the application of 1 ppm of diquat. In spring field studies 0.31 and 2.4 ppm of diquat remained 8 days after the application of 1 and 5 ppm of diquat. Sago pondweed did not translocate either the foliar or root applied Cⁱ⁴ diquat, but the foliar applied C diquat was not. Bluegill remove diquat from water, and C was detected in the 8 tissues analyzed for C 4 content. The hydrosoil from Allerton Lake exhibited greater cation exchange capacity and bound more diquat than the hydrosoils from the five other bodies of water investigated. The hydrosoil from Big Pond contained more organic matter, silt, and clay, and bound less diquat than the hydrosoil from Allerton Lake. The hydrosoils from the other bodies of water varied in their organic matter content, silt, and clay content, and bound less diquat than the hydrosoil from Allerton Lake or Big Pond.
