Common and Chemical Names of Herbicides Approved by the Weed Science Society of America Below is the complete list of all common and chemical of herbicides as approved by the International Organization names of herbicides approved by the Weed Science Society of for Standardization (ISO). A sponsor may submit a proposal America (WSSA) and updated as of September 1, 2010.
for a common name directly to the WSSA Terminology Beginning in 1996, it has been published yearly in the last issue of Weed Science with Directions for Contributors to A herbicide common name is not synonymous with Weed Science. This list is published in lieu of the selections a commercial formulation of the same herbicide, and in printed previously on the back cover of Weed Science. Only many instances, is not synonymous with the active ingredient common and chemical names included in this complete of a commercial formulation as identified on the product list should be used in WSSA publications. In the absence of label. If the herbicide is a salt or simple ester of a parent a WSSA-approved common name, the industry code number compound, the WSSA common name applies to the parent as compiled by the Chemical Abstracts Service (CAS) with CAS systematic chemical name or the systematic chemical The chemical name used in this list is that preferred by the name alone may be used. The current approved list is also Chemical Abstracts Service (CAS) according to their system of available at our web site (www.wssa.net). A complete list of nomenclature in effect since 1972, the period beginning with common and chemical herbicide names, as well as synonyms, old chemical names, and approval information was published in 1995 in Weed Science 43:328–336.
