ASTONENERGY is an excellent grass variety for grazing mixtures, its yield and qualities coupled with superb disease resistance make it a must for all medium and long term grazing mixtures. Its aftermath D-value and good conservation yields mean it is also very suitable for dual purpose mixtures and will combine well with diploid ryegrasses and Hybrid ryegrasses. Its excellent crown rust resistance also makes it ideal for southern England.
