Product Overview

Nufarm Imazuron Herbicide will provide broad-spectrum control of annual and perennial grasses, broadleaf weeds, vines, and hardwoods. It uses the combination of Imazapyr and Diuron as its active ingredient which guarantees long-term control and effective knockdown of tough weeds and grasses. This dispersible granular formula will prevent clogging of nozzles and injection units, as well as ensures residual control of weeds that may germinate in areas that are treated. It is ideal for use on non-crop areas like utility plant sites, petroleum tank farms, pumping installations, storage areas, railroads, fencerows, farmyards, or areas where bare ground is wanted. 

Always use a surfactant for post-emergent applications.  This is a vegetation management product and should only be used by an experienced user as it can leach.

    Mixing Instructions

    By Paul on 06/18/2019

    This product works great if you get it mixed properly. I put 2.5 lbs. in 30 gal of water and it was very hard to get all of it to dissolve or go into solution so it could be sprayed evenly on the area I needed to treat. A mix ratio of product to water would be helpful!!!
