    Atrazine 900 WG Herbicide is not registered to control Cobbler's Peg as a pre-emergent in pasture situations. Hence, there is no boom spray rate available.

    Asked by Wade on April 30, 2023 4:41 pm
    Answered by the admin

    Atraquest 900 WG Herbicide is not registered to control Giant Rat's Tail Grass (GRT). When applied to the soil, atrazine is absorbed by the roots of the target plants, which disrupts the photosynthesis process, ultimately leading to their death. Control over some perennial grasses can be achieved with atrazine, and it's important to note that the effectiveness of atrazine on perennial grasses can depend on several factors, such as the timing and method of application, the dosage, and the age and growth stage of the target plants. We are unaware of off-label trials of Atrazine on GRT.
