ERM-1466: Chemical Weed and Brush Control Reference Guide for Rangelands

Potential herbicide references for weed and brush species in the 1466 are listed by target weed or brush species in the Index found on page three. The second column on data pages include herbicide names. For a list of the product names these herbicides are typically sold as, please refer to page five.
It is recommended that herbicides are chosen based on the following considerations:

• Whether the user would like to make a broadcast application or treat individual plants (included in third and fourth columns).
• The effectiveness (L, M, H, VH), which tells you the percentage of plants you should expect to kill with that herbicide and rate. For percent kill ranges, see page four.
• How the chemical is applied. Reference the fifth column for the method to use, such as foliar, stem, cut-stump, aerial or other.

Detailed instructions on how to use ERM-1466 can be found on page two of the publication. Tips on measuring and mixing herbicides can be found on page six.

Data can be submitted for inclusion in ERM-1466 by any group, including university researchers, industry, organizations and cooperatives who have collected accurate data including procedures that can be replicated.
Data submissions are reviewed, discussed and voted on by the Texas A&M AgriLife Extension herbicide use committee. Before collecting data for submission to ERM-1466, please carefully read the Guidelines for Data Submissions and become familiar with the submission form.
