摘要:
Described are preferred methods and compositions for controlling aquatic weeds that involve the use of fluridone in combination with at least one additional selected herbicidal agent, which is preferably penoxsulam, bensulfuron-methyl, bispyribac-sodium, and imazamox (ALS inhibitors). Additional preferred compositions and methods can further involve the use of triclopyr or 2,4-d (auxinic herbicides) in the herbicidal composition. Preferred herbicidal combinations allow for enhanced control and/or selectivity when treating a body of water to control a target weed population, such as a hydrilla, watermilfoil, curlyleaf pondweed, and/or Brazilian elodea weed populations.
摘要:
Described are preferred solid herbicidal formulations that include one or more herbicides in combination with a solid carrier, as well as methods of manufacture and use thereof. Solid herbicidal formulations are designed to deliver a moderated release of the incorporated load of herbicidal agent(s), for example to enhance uptake by target plants and/or the ability to spatially control a plant population within a body of water that exhibits flow.
摘要:
Described are methods and systems for managing watermilfoil populations in bodies of water such as lakes. In certain forms, the methods and systems involve the use of genetic analysis to determine whether a watermifoil population targeted for herbicidal control has a genetic relationship with hybrid (e.g. Northern×Eurasian) watermilfoil plants known to exhibit herbicidal tolerance. In one aspect, it has for the first time been discovered that such hybrid watermilfoil plants include significant clustering groups that exhibit herbicide tolerance. This can be used in the design and implementation of herbicidal treatment regimens against a new target watermilfoil population.
