Control aquatic weeds using a combination of halauxifen, florpyrauxifen and other aquatic herbicides

Abstract

The present invention describes the use of fluopyridinate or fluopyridinate or agriculturally acceptable esters or salts thereof with one or more of diquat dibromide, copper salts, doxorubil or fluflufenac. or combinations of agriculturally acceptable salts or esters thereof for controlling aquatic weeds. When treating water bodies, the herbicidal composition allows effective control and / or selection against target weed populations such as amaranth, oil sedge, barnyardgrass, early waterweed, barnyardgrass, duckbill, stephanotis, softgrass, Aquatic weeds, Eurasian Myriophyllum and / or Acanthopanax.

Description

Background technique [0001] In bodies of water and wetlands, aquatic plants often grow into undesirable weeds. Three such weeds are hydrilla, curlyleaf pondweed and watermilfoil, including Eurasian watermilfoil. Waterbody treatments used to remove or control undesirable aquatic weeds are often complicated because the agents used to control undesirable weeds may also adversely affect desirable or native plant life. Aquatic herbicides need to be in contact with aquatic (submersible, emergent or floating) plants for a period of time to be effective. Some herbicides require long-term exposure in water (one or more months) to control certain submersed, emergent, or floating plants, which may adversely affect non-target species. Prolonged exposure may be difficult to achieve in a flowing environment. Inadequate exposure may result in poor efficacy or failure. Therefore, methods or techniques that reduce exposure time and / or reduce the concentration of pesticides used to control ...

Problems solved by technology

However, this is not always the case, and higher application rates can have adverse or undesired effects on beneficial aquatic plants and aquatic organisms, and may not adequately compensate for the rate needed to control target aquatic plants
