Best Management Practices
- Effective herbicide resistance management requires a balance of chemical and non-chemical tactics, including:
- Decreased reliance upon chemical weed control and increased diversity of traditional cultural practices, such as selection of appropriate turf species for the scenario or environment (e.g. aesthetic, use, or management capabilities). The emphasis should be on providing a dense and competitive turfgrass sward. A holistic approach of managing soil and plant health is required in order to do so.
- When herbicides are used, diversify sites of action between years and within seasons.
- Emphasis on both preemergence followed by early-postemergence means of control, which effectively reduces the amount of annual bluegrass exposed to postemergence strategies.
- Use labelled rates at appropriate timings and stages of growth.
- Use multiple herbicide sites of action (SOAs) with overlapping spectrums of weeds controlled.
- Scout after application and avoid allowing weeds to go to seed or proliferate vegetatively.
