Key Points:
- A screening trial using a log-sprayer was able to give indications of the relative efficacy of different herbicides, at different rates, on a range of grass weeds. Results show several promising options.
- Always consult your agronomist before implementing decisions concerning herbicide screening results. NB. Use of product in this trial does not constitute a recommendation.
- The interpretation of the scores in table 1 is based on; 0-3 = fully tolerant, 3-5 = mostly tolerant, 5-8 = mostly susceptible and 8-10 = fully susceptible. However where doubt exists around the repeatability of the data based on previous results, the summary of each species may be adjusted. These figures only apply to effect on vegetative growth and may not take account of effects on subsequent grain or seed production.
