AQUATIC HERBICIDE INFORMATION

The Aquatic Herbicide Procellacor® will be used for control of Eurasian Watermilfoil (EWM) in the State of Idaho during the 2023 season. Information about this USEPA registered Aquatic Herbicide, including the product label and the Safety Data Sheet (SDS), can be downloaded from the document library below.

ProcellaCOR EC® (liquid) is a selective systemic aquatic herbicide for management of freshwater aquatic vegetation in slow-moving/quiescent waters with little to no continuous outflow: ponds, lakes, reservoirs, freshwater marshes, wetlands, bayous, drainage ditches, and non-irrigation canals, including shoreline and riparian areas in or adjacent to these sites.  Also for managment of invasive freshwater aquatic vegetation in slow-moving/quiescent areas of rivers (coves, oxbows, or similar sites).

Florpyrauxifen-benyl is the active ingredient in ProcellaCOR®. Florpyrauxifen-benzyl is a systemic herbicide that is taken up by aquatic plants.  The herbicide mimics the plant growth hormone auxin that causes excessive elongation of plant cells that ultimately kills the plant. Susceptible plants will show a mixture of atypical growth (larger, twisted leaves, stem elongation) and fragility of leaf and shoot tissue. Initial symptoms will be displayed within hours to a few days after treatment with plant death and decomposition occurring over 2 – 3 weeks

Waters treated with ProcellaCOR® may be used for swimming, fishing, and drinking water. Restrictions exist for irrigation water to agricultural, non-agricultural vegetation, but turf may be irrigated immediately after treatment. Please see the label for specific ProcellaCOR EC® precautions.
