Product Overview

Shark H2O herbicide is a predatory postemergent product that controls broadleaf weeds and sedges in rice. It takes care of weeds quickly, even those that are tolerant to ALS herbicides.

Shark H2O herbicide loves the water, so there’s never the need to drop the water level in your field to make it more effective.

Apply by air with a direct dry application (DDA) or a direct stream application (DSA) delivery so there’s no hassle using ground application equipment.
