BA-189 (protected by Australian Plant Breeder's Rights); UltimateFlora® (registered trade mark of Environmental Turf, Inc. in the USA).


BA-189 Zoysia is a medium- to coarse-textured turfgrass that was selected and bred for darker leaf color, fewer seed heads, a more refined leaf structure and, depending on location, faster growth rate than the long-standing standard variety 'Meyer' zoysiagrass. Likely to be commercially available in Australia in 2018.

Other comments

BA-189 was developed in Florida by researchers at the University of Florida. A benefit of zoysiagrass is that it is less common to see attacks by army worm and sod web worm. The high fibre and lignin present within the leaf blades, which also assist for wear tolerance, make it tough for such attacks. To put it simply, the foliage is "too" tough and unfavorable for chewing mouthparts of such pests.
