Product Overview

Imazacast Aquatic Herbicide is a professionally formulated selective herbicide that gives control of both submerged and surface vegetation in aquatic environments. It can be administered directly or diluted to control and suppress submerged aquatic plants. It can treat emergent and floating vegetation as a broadcast or spot treatment. This product is quickly absorbed by leaves and transported to the developing points, limiting growth. Once a susceptible plant develops a yellow appearance, it will eventually die or be severely growth inhibited. Excellent for aquatic sites, slow-moving bodies of water, roadsides, fence rows, and industrial non-crop areas.
