登记用途：Uses: Formerly used as a pre- and post-emergence herbicide for control of annual broad-leaved weeds and some grasses in soy beans、deciduous fruits、vegetables、strawberries、conifers、and other crops、Also used to control mosses in turf、non-crop land、and greenhouses、Discontinued by Ciba-Geigy Ltd. sometime before 1994、[HSDB]、Farming (Pesticides) [Category: Industry]、Selective herbicide ... pre- and post-emergence control of annual broad-leaved weeds and some grasses in peas、beans、carrots、celery、celeriac、onions、leeks、garlic、chives、fennel、parsley、dill、tomatoes、cucurbits、soya beans、ornamentals、fruit trees、and conifers. Control of mosses in ornamental and sports turf、on paths and non-crop land、and in glasshouses.、Former use、Use Classification: Pharmaceuticals、HERBICIDES、Methods of Manufacturing: REACTION OF PHOSGENE WITH P-CHLOROPHENOXYANILINE TO PRODUCE 4(4'-CHLOROPHENOXY)PHENYLISOCYANATE、FOLLOWED BY REACTION OF THIS WITH DIMETHYLAMINE.、REACT P-CHLOROPHENOXY-PHENYLUREA OR P-CHLORO-PHENOXY-PHENYL ISOCYANATE WITH DIMETHYLAMINE.、p-Chlorophenol + p-chloronitrobenzene + dimethylcarbamoyl chloride (ether formation、nitro reduction、dehydrochlorination)、Formulations、Preparations: Mixed formulations: (chloroxuron +) iron sulfate、dichlorophen + iron sulfate.、'Tenoran' WP、wettable powder、500 g ai、kg.、Consumption Patterns: HERBICIDE、OF WHICH APPROXIMATELY 80% IS USED ON SOYBEANS、10% ON DECIDUOUS FRUITS、AND 10% ON VEGETABLES (1975)、Use in US agriculture (1000 pounds AI、yr): 1982 - 18、1989 - 62、U.S. Production: (1975) 4.54X10+8 G (CONSUMPTION)、General Manufacturing Information: COMPATIBLE WITH OTHER HERBICIDES.、APPLICATION METHODS: PREEMERGENCE BROADCAST OR BAND TREATMENTS TO THE SURFACE OF THE SOIL AT PLANTING、SOIL INCORPORATION OF CHLOROXURON DOES NOT IMPROVE PERFORMANCE. POSTEMERGENCE TO CROPS & POSTEMERGENCE TO WEEDS、FOR BEST RESULTS APPLY JUST AFTER WEED EMERGENCE BUT CERTAINLY BEFORE WEEDS ARE 2 INCHES HIGH. MAKE APPLICATION WITH CONVENTIONAL SPRAY EQUIPMENT. RATES: RANGE: 1-4 LB、ACRE、1-1.5 LB、ACRE FOR SOYBEANS、3-4 LB、ACRE FOR CARROTS & ONIONS. USUAL CARRIER: WATER AT 25 TO 40 GPA、CONSTANT AGITATION、SCREEN SIZE 50 MESH OR LARGER.、CHLOROXURON IS ABSORBED BY BOTH ROOTS AND LEAVES、RECOMMENDED FOR CONTROL OF WEEDS IN STRAWBERRIES AT 3.5-4.5 KG AI、HA、PRE-EMERGENCE OR AFTER TRANSPLANTING、OR IN SOYBEANS、ORNAMENTALS & CONIFERS @ SIMILAR RATES. AT THESE RATES IT DISSIPATES TO NON-PHYTOTOXIC CONCN WITHIN 2 MONTHS.、Discontinued by Ciba-Geigy Ltd.。
