International Survey of Herbicide Resistant Weeds

Monday, May 23, 2016

There are currently 470 unique cases (species x site of action) of herbicide resistant weeds globally, with 250 species (145 dicots and 105

 monocots). Weeds have evolved resistance to 23 of the 26 known herbicide sites of action and to 160 different herbicides. Herbicide

 resistant weeds have been reported in 86 crops in 66 countries. The website has 2264 registered users and 492 weed scientists have contributed

 new cases of herbicide resistant weeds. View Recent Additions, Site of Action Summary, or the Herbicide Classification System.

About This Survey

The purpose of this survey is to monitor the

 evolution of herbicide-resistant weeds and

 assess their impact throughout the world. The

 site is a global collaboration between weed

 scientists with a common goal of understanding,

 preventing and managing the occurrence of

 herbicide-resistant weeds.

NEW : Genomic DNA Sequences that Encode for Herbicide Targets

Darci Giacomini has created this database to (1) give quick access to the most common herbicide resistance genes across a wide range of

 weedy species and (2) provide a resource for researchers interested in discovering these gene sequences from weed species not listed here.

Removal of Synthetic Auxin Resistant Tripleurospermum perforatum from the survey.

Upon review of this case it was determined that it did not fit the criterion for inclusion in the survey. A full explaination can be found in the

 following PDF : Why Synthetic Auxin Resistant Tripleurospermum perforatum was removed from the survey.
