4570 Imazapyr Imazapyr is a non-selective herbicide for non-crop land applications which is particularly effective on hard-to-control perennial grasses. Its mode of action is non-selective and absorbed by foliage and rapidly translocated. Imazapyr is absorbed by the leaves and roots, and moves rapidly through the plant. It accumulates in the meristem region (active growth region) of the plant. In plants, imazapyr disrupts protein synthesis and interferes with cell growth and DNA synthesis. It controls vegetation by interfering with an enzyme pathway. It inhibits acetolactate synthase. It is used for the control of a broad range of weeds including terrestrial annual and perennial grasses and broadleaved herbs, woody species, and riparian and emergent aquatic species. It is used to eliminate Lithocarpus densiflorus (Tan Oak) and Arbutus menziesii (Pacific Madrone). Additionally, imazapyr is used to control annual and perennial grass and broadleaved weeds, brush, vines and many deciduous trees. 81334-34-1 54738 C13H15N3O3 White powder.
