Resistance Surveys
WA’s herbicide resistance status
The herbicide resistance survey assesses the state of herbicide resistance to commonly used herbicides in the Western Australian wheatbelt for important weeds. Surveys were conducted over the last 20 years to determine the frequency and extent of herbicide resistance in crop weeds. Weed seed samples collected were screened for resistance to commonly used herbicides at recommended field rates.
