Application Rates

Aminocyclopyrachlor, an active ingredient in Navius herbicide, stops the growth of plants by interfering with hormonal balance necessary for normal shoot and root development. The herbicide has unique features acting via a distinctive mechanism that targets a family of auxin receptor complexes. Metsulfuron-methyl, a Group 2 herbicide, causes the rapid cessation of plant cell division and growth.

Best Practices

• Superior broad-spectrum control of over 40 weed species, including undesirable brush/woody plants in non-crop areas
• It promotes the grass understory and helps preserve desirable vegetation
• Two modes of action for effective resistance management
• Quickly taken up by the leaves, stems and roots of plants
• Low use rates per hectare for reduced chemical load on the environment
• Grazing animals do not have to be moved off the pasture or rangeland before, during or after applying Navius
• Brush and broadleaf weed control with one product
