Potentiating herbicidal compositions of auxin transport inhibitors and substituted urea herbicides

摘要

The present invention is directed to the use of certain auxin transport inhibiting semicarbazones to potentiate the herbicidal activity of other herbicides. The present invention includes potentiating herbicidal compositions of these auxin transport inhibitors and substituted urea herbicides such as thiadiazuron. These potentiating herbicidal compositions have been found especially useful in combating or controlling the growth of broadleaf weeds, especially when applied postemergence to the locus of these weeds.
