| 应用领域 | Uses: Used as hybridizing agent for wheat (plant growth regulator)、[Merck Index] A plant growth regulator used in the production of hybrid wheat seed、Only used by specially-trained seed company personnel、[Reference #1]、Farming (Pesticides) [Category: Industry]、Plant growth regulator for use in the production of hybrid wheat seed. Clofencet is registered for use on wheat as a seed crop and on rotational crops of the cereal group (except rice、wild rice、sweet corn and wheat) and soybeans.、For clofencet potassium salt (USEPA、OPP Pesticide Code: 128726) ACTIVE products with label matches.、Clofencet Potassium Salt、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.、Formulations、Preparations: 91.0% solid technical powder、23.1% water soluble concentrate manufacturing use、22.4% water soluble concentrate end-use (2 lb active ingredient per gallon)、Consumption Patterns: It is estimated that at maximum market saturation、clofencet will be applied to less than 300、000 acres of the total US wheat acreage (less than or equal to 0.5%). Initial use is projected on 12、000 acres or 0.02% of the total US wheat acreage. |
