| 应用领域 | Uses: 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]、Farming (Pesticides) [Category: Industry]、For imazapyr (USEPA、OPP Pesticide Code: 128821) ACTIVE products with label matches.、SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、Herbicide、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、paved areas、driveways、patios、parking areas、walkways、various water bodies (including ponds、lakes、streams、swamps、wetlands、and stagnant water)、and urban areas. Imazapyr may also be used on recreation areas、athletic fields、and golf course roughs.、This is a man-made compound that is used as a pesticide.、Household Products: Information on 6 consumer products that contain Imazapyr in the following categories is provided:、• Pesticides、Methods of Manufacturing: 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.、Formulations、Preparations: Aqueous liquid with wetting agent、Imazapyr is formulated as a liquid、a wettable powder (in water soluble bags only)、and a granular.、Soluble concentrate、granule、emulsifiable concentrate、Mixtures: imazapyr + diuron、For more Formulations、Preparations (Complete) data for IMAZAPYR (34 total)、please visit the HSDB record page.、General Manufacturing Information: The WHO Recommended Classification of Pesticides by Hazard identifies imazapyr as unlikely to present an acute hazard in normal use、Main Use: herbicide.、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.、Synthesis during manufacture results in technical active ingredient with a purity >95%. No additional purification is needed.、(1988) 190 kg active ingredient applied to 300 ha of National Forest lands in the United States、15% of which were in the southern US. |
