Herbicide Resistance

This indicator assesses the number of occurrences of herbicide resistant weeds. Herbicide resistance is the ability of a weed to survive an herbicide application that had been used to contain that population. As unwanted plants compete with crops, issues of crop loss and contamination arise. To estimate antimicrobial and agrochemical resistance, data from the Weed resistance database (International Survey of Herbicide Resistant Weeds) was used. Please note that the source data for this indicator is only available on a country level.
