Imazapyr is a non-selective herbicide 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. [1] It is used to control annual and perennial grass and broadleaved weeds, brush, vines and many deciduous trees.
Imazapic is a chemical used as an herbicide. It controls many broad leaf weeds and controls or suppresses some grasses in pasture, rangeland and certain types of turf. It has a half-life of around 120 days in soil. [1] [2] Imazapic is considered an environmental hazard due to its harmful effects on aquatic life. [3]
Imazaquin along with imazamethabenz-methyl, imazapyr, imazapic, imazethapyr, and imazamox comprise the class of synthetic compounds termed the imidazolinone herbicides. These chemicals all feature an imidazolinone ring with a carboxylic acid group attached to the backbone. [4] They vary in the attached ring structure.
In the same report, it added the "yield loss plus increased herbicide cost may result in an average estimated loss of $28 per acre" if atrazine were unavailable to corn farmers. [4] In 2006, the EPA concluded that the triazine herbicides posed "no harm that would result to the general U.S. population, infants, children or other... consumers." [5]
One major complication to the use of herbicides for weed control is the ability of plants to evolve herbicide resistance, rendering the herbicides ineffective against target plants. Out of 31 known herbicide modes of action, weeds have evolved resistance to 21. 268 plant species are known to have evolved herbicide resistance at least once. [59]

For much of the past decade, policymakers and analysts have decried America's incredibly low savings rate, noting that U.S. households save a fraction of the money of the rest of the world.
There is a pharmaceutical drug on the market, nitisinone, that was originally under development as an herbicide as a member of this class and is used to treat an orphan disease, type I tyrosinemia. HPPD inhibitors can be classified into three fundamental chemical frameworks: pyrazolones, triketones, and diketonitriles.
