The Aquatic Herbicide Aquathol K® will be used for the control of Eurasian Watermilfoil (EWM) in Lake Coeur d'Alene, Kootenai County, Idaho during the 2019 season. Information about Aquathol K® and DMA 4 IVM, including the product label and the Material Safety Data Sheet, can be downloaded from the document library below.
Aquathol K® (liquid) is an aquatic herbicide labeled for control of aquatic plant growth in quiescent, slow moving, and flowing water aquatic sites. Endothall, the active ingredient in Aquathol K®, is rapidly absorbed by aquatic plant foliage, interfering with plant protein synthesis and other plant processes. Aquathol K® is a contact herbicide effective against a broad range of aquatic plants. This product does not affect beneficial emerged plants such as Spadderdock, Water Lilies, Water Stargrass, Chara or Nitella.
Waters treated with Aquathol K® may be used for swimming, fishing, and irrigating turf. Restrictions do apply for potable water. Phytotoxicity, or damage, is not expected on plants or crops irrigated with Aquathol K® treated water, however all species and varities have not been tested. Please see the label for specific Aquathol K® precautions.
DMA 4 IVM® (liquid) is an herbicide labeled for selective control of may broadleaf weeds in a variety of sites including aquatic areas.
2,4-D, the active ingredient in DMA 4 IVM®, is absorbed and translocated by aquatic plant foliage, interfering with plant metabolism, and providing systemic control to susceptible broadleaf plant species such as Eurasian watermilfoil. 2,4-D is highly selective for Eurasian watermilfoil when used at the labeled rate leaving native aquatic species relatively unaffected.
Waters treated with DMA 4 IVM® may be used for swimming and fishing. Restrictions do apply for potable water and irrigation of some crop and non crop sites. Please see the label for specific DMA 4 IVM® precautions.
