数据库记载的用途

Used as non-selective, pre- and post-emergent herbicide applied as either the acid or isopropylamine salt; Registered for use on corn, grass, and a variety of commercial and residential use sites; [Reference #1]
Imazapyr is a systemic, non-selective herbicide used for the pre- and post-emergence control of a broad range of weeds, including terrestrial annual and perennial grasses, broad-leaved herbs, woody species, and riparian and emergent aquatic species. ... Imazapyr may be used in a variety of agricultural, commercial, and residential settings. Use sites include corn, forestry sites, rights-of-way, fence rows, hedge rows, drainage systems, outdoor industrial areas, outdoor buildings and structures, domestic dwellings,
Information on 6 consumer products that contain Imazapyr in the following categories is provided:
2,3-Pyridinedicarboxylic acid undergoes dehydration (to form the anhydride), a condensation reaction, hydrolysis, is cyclized (to form the imidazolinone ring), and is precipitated as the manufacturing use product.
Imazapyr is produced by reaction of 2,3-dicarboxymethylpyridine with 2-aminoamide-3-methylbutane in the presence of two equivalents of tert-butoxide.
Imazapyr technical was first registered in 1985; however, a non-crop end use product had been previously registered in July 1984. The first food use on corn was registered in April 1997. In 2003, the aquatic and grassland uses were registered which resulted in the establishment of additional tolerances.
