| 应用领域 | Uses: Used as pre- and post-emergence herbicide to control weeds on cereal grains、pasture、rangeland、industrial sites、and turf grass、[Reference #1]、Farming (Pesticides) [Category: Industry]、For chlorsulfuron (USEPA、OPP Pesticide Code: 118601) 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.、A selective preemergence or early postemergence herbicide used at low rates.、This is a man-made compound that is used as a pesticide.、Methods of Manufacturing: Chlorsulfuron is produced by reaction of 2-sulfonylisocyanate chlorobenzene with 2-amino-4、6-dimethoxy-1、3、5-triazine.、Prepn: G. Levitt、German patent 2715786、idem、United States of America patent 4127405 (1977、1978 both to du Pont).、Formulations、Preparations: NUP 08136 (Nufarm Americas、Inc): Active ingredient: chlorsulfuron 15% and metsulfuron 48%.、Nufarm Chlorsulf SPC 75 WDG Herbicide (Nufarm Americas、Inc): Active ingredient: chlorsulfuron 75%.、ETI 123 01 H-D2 (Nufarm Americas、ETI 122 01 H-D (Nufarm Americas、Inc): Active ingredient: chlorsulfuron 62.5% and metsulfuron 12.5%.、For more Formulations、Preparations (Complete) data for Chlorsulfuron (33 total)、please visit the HSDB record page.、General Manufacturing Information: The WHO Recommended Classification of Pesticides by Hazard identifies Chlorsulfuron (technical grade) as unlikely to present an acute hazard in normal use、Main Use: herbicide.、Application methods: Preemergence or early postemergence treatments show the most activity on annual grass weeds and broadleaf weeds. Later postemergence treatments are effective on most broadleaf weeds but less effective on grasses. Treatments may be made with aerial or ground equipment. Rates: 0.2-0.5 oz、acre preemergence or postemergence on wheat and only postemergence on barley、oats、rye and flax. 0.5-1.5 oz、acre for fallow weed control. Usual carrier: water 1.5-40 gallons、acre plus a surfactant @ 0.1% by volume for control of emerged weeds. |
