The new Tetra-plus blend from Barenbrug has been revised and now consists of all tetraploid perennial ryegrass varieties. New perennial ryegrass varieties selected by Barenbrug in United States have improved stand density and winterhardiness.
Tetra-plus consists of new tetraploid perennial ryegrass variety Remington. Research has shown that Remington is very persistent, even under very cold temperatures at trial sites in New York, Pennsylvania and Wisconsin, whereas many other varieties in these university trials were winterkilled. Tetra-plus is a unique combination of good forage quality, high productivity and stand longevity. Tetra-plus is ideal for green-chop, hay and silage making.
