Abstract:

During the registration process for evaluating aquatic herbicides, it is important to determine both the efficacy on target vegetation as well as the potential impacts on non-target vegetation. Herbicide applications for submersed weeds can negatively impact some non-target emergent species. Factors such as the plant species and growth stage, and the herbicide treatment rates and exposure time can often dictate the selective potential of an aquatic herbicide. There are currently several new herbicide modes of action being evaluated for the aquatic market, and determination of selectivity is important in determining potential use patterns. This study was conducted to determine the effect of submersed applications of bispyribac-sodium 2,6-bis4,6- dimethoxypyrimidin-2-yloxy benzoic acid on arrowhead Sagittaria latifolia Willd., pickerelweed Pontederia cordata L., and duck potato Sagittaria lancifolia L..
