Shield was specifically bred from germplasm known to have high survivability in hot, humid regions crossed with plants highly resistant to gray leaf spot, stem rust and other disease. Further screenings have produced a ryegrass you can plant with confidence. Great turf that will endure the elements and stand tuff against disease.
