Lush tetraploid Italian ryegrass provides exceptional summer yield and quality (reduced aftermath heading). Lush has strong second year production, better than traditional Italians, growing luscious feed for longer. Lush has exceptional rust tolerance for better consumptionby stock. Rarely has an Italian tetraploid ryegrass shown such superb summer feedquality, high yield potential and persistence.


Lush tetraploid Italian ryegrass comes with AR37 endophyte. AR37 endophyte has been shown to provide superior pest protection from Argentine Stem Weevil, Pasture Mealy Bug, Black Beetle, Root Aphid and Porina in both diploid and tetraploid long rotation and perennial ryegrasses. Lush AR37 showed greater persistency than Feast II in PGG Wrightson Seeds’ trials in both Canterbury and Waikato.

Lush Italian Ryegrass
"Lush AR37 was extremely competitive with barley and made a significant contribution to the silage yield of about 9 t DM/ha taken in late January. Subsequent to the silage being taken, the Lush AR37 has lived up to the hype so far, in terms of both yield and quality."
