| 应用领域 | Uses: Used as pre- or post-emergence herbicide for control of annual broad-leaved and grass weeds in cereals、rice、sugar beets、ornamentals、vegetables、and public easements、No longer produced or marketed in the US、[HSDB]、Prohibited for use in the US、U.K.、Federal Republic of Germany、Sweden、and the Russian Federation、and highly restricted in many other countries、[INCHEM] Banned in the EU、[eChemPortal: ESIS]、Farming (Pesticides) [Category: Industry]、For nitrofen (USEPA、OPP Pesticide Code: 038201) there are 0 labels match.、SRP: Not registered for current 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.、Nitrofen is a contact herbicide for pre and post emergence control of annual grasses and broadleaf weeds on a variety of food and ornamental crops. Nitrofen has been applied in approximately 25 states by growers of rice、broccoli、cauliflower、cabbage、brussel sprouts、onions、garlic、and celery. Nitrofen has also been used in nurseries growing roses and chrysanthemums and on rights-of-way. ... Nitrofen has not been used around homes and gardens.、Formerly as a herbicide、US、Use Classification: HERBICIDES、Methods of Manufacturing: Nitrofen can be made by reaction of 2、4- dichlorophenol with p-chloronitrophenol in the presence of a base.、Impurities: A sample reported ... to be more than 98% pure was found ... to contain the following five impurities at unspecified levels: para-chloronitrobenzene、bis(para-nitrophenyl)ether、2、4-dichloro-2、2-dinitrophenyl ether、2-chloro-4-nitrodiphenyl ether and 4-chloro-4-nitrophenyl ether. Four other unidentified impurities were also observed in the mg、kg (ppm) range. Technical nitrofen may also contain 2、7-dichlorodibenzodioxin.、Formulations、Preparations: NITROFEN 7% AI、GRANULE、COMBINED FORMULATION 5% + ((4-CHLORO-O-TOLYL)OXY)ACETIC ACID ETHYL ESTER 0.7%、5% AI、GRANULE (FOR UPLAND)、COMBINED FORMULATION 6% + ((4-CHLORO-O-TOLYL)OXY)ACETIC ACID BENZYLTRIETHANOLAMINE SALT 0.4%、25% AI、EMULSIFIABLE CONCENTRATE COMBINED FORMULATION 5% + 4-((4-CHLORO-O-TOLYL)OXY)BUTYRIC ACID 0.6% + 2-AMINO-3-CHLORO-1、4-NAPHTHOQUINONE、50% AI、WP、COMBINED 0.75-7% + FERTILIZERS.、FROM TABLE、Granules、emulsifiable concentrate、wettable powder.、Mixed formulations: (nitrofen plus) diniterb、neburon、linuron.、Trade Names: Mezotox、Niclofen、NIPR、Tokkorn.、Consumption Patterns: HERBICIDE FOR VEGETABLES、89%、HERBICIDE FOR SUGAR BEETS、11% (1978)、The direct crop use of nitrofen for 1980 was estimated as 882、000 pounds.、U.S. Production: (1975) 3.63X10+8 G (CONSUMPTION)、(1978) 4.09X10+8 G (CONSUMPTION)、U.S. Imports: (1976) No Data、(1978) No Data、U.S. Exports: (1976) No Data、General Manufacturing Information: Benzene、4-dichloro-1-(4-nitrophenoxy)-: ACTIVE、The WHO Recommended Classification of Pesticides by Hazard identifies nitrofen as an active ingredient believed to be obsolete or discontinued for use as a pesticide.、Effective when left as a thin layer on the soil surface、activity is rapidly lost on incorporation in soil. |
