Key Points
A screening trial using a log-sprayer gave indications of the relative efficacy of different herbicides, at different rates and timings on a range of weeds and the clover crop itself.
- Many of the herbicides stunted the clover, especially at the May timing (1-2 trifoliate leaves), but generally all but the highest rates recovered.
- Although many herbicides damaged the plants when applied in May, the follow-up application in August was needed to maximise weed control.
