ERM-1466: Chemical Weed and Brush Control Reference Guide for Rangelands
The Texas A&M AgriLife Extension Service herbicide use committee documents past and current research related to the effectiveness of herbicides on potentially unwanted weed and brush species. These assessments are compiled in ERM-1466: Chemical Weed and Brush Control Reference Guide for Rangelands, which is often referred to as ERM-1466 or the 1466. ERM-1466 is based on scientific research and is for educational purposes only. It is not intended as a regulatory or opinion document.
Inclusion of an herbicide application in ERM-1466 should not be interpreted as a product endorsement on behalf of Texas A&M AgriLife Extension or members of the herbicide use committee.
Effectiveness ratings are only assigned when the submissions of herbicide treatment data are robust and reflect a suitable amount of data over space and time that can be easily replicated.
The effectiveness ratings are designated a Low (L: 0-35% plant kill); Moderate (M: 36-55% plant kill); High (H: 56-75% plant kill); or Very High (VH: 76-100% plant kill).
