NZ vs US turf ryegrass
When it comes to the choice between NZ and US turf type perennial ryegrass Cultivars there is some confusion. Both of these are predominantly perennial ryegrass varieties and both make claims about their performance.
The problem is having looked at the research we think we have got confused and completely misunderstood it. The trial we refer to throughout this is available as a free download at the end of this report.
- Mediterranean turf ryegrass cultivars will germinate and establish more rapidly later in the autumn, in colder conditions;
- Mediterranean cultivars grow more over winter and
- They are better for managing winter grass.
- One thing that isn’t different is that they all are susceptible to sulfonylurea herbicides.
Mediterranean turf ryegrass cultivars will germinate and establish more rapidly later in the autumn, in colder conditions.
Mediterranean cultivars grow more over winter.
With this one we thought no issue. New Zealand is generally regarded as being colder than Australia so these Auckland based trials should be a good test of ‘winter activity’. If the above statement is true then the NZ Mediterranean cultivars should outperform the Continental germplasm.
Poa management
The third advantage, is that Poa annua blends into the mid-green foliage of the Mediterranean cultivars. This is in contrast to the Continental cultivars where it sticks out like the proverbial.
