Imazaprox uses and types: Clearcast is

• A. A fungicide used on shoreline soils
• B. A liquid and granule product that controls all aquatic plants; systemic, selective herbicide
• C. A nutrient supplement for water bodies
• D. A contact herbicide for algae only

Answer: (B)

Clearcast is an aquatic herbicide product that contains imazapyr and is available as both a liquid and a granular formulation, so applicators can choose the best delivery method for the site and weed type. Imazapyr is taken up by the plant and moved within its tissues, so it translocates to the root system and kills the whole plant rather than just the parts touched by the spray. This systemic action, combined with its use on a range of aquatic vascular plants, is why it’s described as systemic and selective in practice. It’s used to control aquatic weeds rather than algae, and it isn’t a fungicide or a nutrient additive.
