Ryegrass endophyte options

AR37 – maximum protection for maximum production

Use ryegrass with AR37 endophyte for the best available insect protection for your pastures, so you improve animal productivity and pasture persistence.

Ryegrass with AR37 gives you simple, economical insect control and around the clock protection from most pasture pests. AR37’s continual and superior insect protection ensures maximum pasture production and better pasture persistence allowing higher animal productivity.

  • Benefits:
  • AR37 provides greater insect protection than any commercially available ryegrass endophyte.
  • Provides continual protection against Argentine Stem Weevil, Adult Black Beetle, Pasture Mealy Bug, Root Aphid and Porina*
  • Improves tiller density and persistence of perennial ryegrass.
  • Maximises animal performance‡
  • Provides higher pasture productivity allowing higher animal productivity and more profit.

AR37 offers greater security and profit potential for your farm operation than any other ryegrass endophyte.

* Good control of Porina has been shown in pot trial studies, the level of field resistance is still to be confirmed.
‡ AR37 can cause ryegrass staggers in grazing livestock. Research has shown AR37 staggers to be less frequent, less severe and of shorter duration than standard endophyte. Animal performance studies measuring liveweight gain and milk production have not shown any reduction in animal performance as a result of animals grazing ryegrass with AR37 endophyte when compared to AR1 or ryegrass without endophyte.

Endo5 – superior insect protection for tetraploid ryegrass

Use Endo5 for superior insect protection in tetraploid ryegrasses.

Ryegrass with Endo5 protects against a range of pasture insect pests including Argentine Stem Weevil, Adult Black Beetle and Pasture Mealy Bug. Farmers using tetraploid ryegrass to improve animal productivity will choose Endo5 to increase pasture persistence.

  • Benefits:
  • Endo5 provides excellent insect protection for tetraploid ryegrasses.
  • Provides continual protection against Argentine Stem Weevil, Adult Black Beetle and Pasture Mealy Bug.
  • Does not product lolitrem B a compound known to cause ryegrass staggers‡

Endo5 insect protection for tetraploid ryegrass.

‡Endo5 produces low levels of ergovaline, that may, under certain circumstances, reduce animal performance. Ergovaline levels are highest in the crown of the plant during summer and autumn. To minimise any adverse affects, avoid prolonged set stocking, or grazing fresh regrowth of such pastures during summer and autumn.

AR1 – the safer ryegrass endophyte

Ryegrass containing AR1 endophyte confers a high level of animal safety while providing a moderate range of insect protection.

  • Benefits:
  • Animal productivity equivalent to ryegrass without endophyte and the novel endophyte AR37.
  • Provides continual protection against Argentine Stem Weevil and Pasture Mealy Bug.
  • Does not produce lolitrem B or ergovaline, compounds known to affect animal health and performance.
  • Preferred option for farmers grazing horses and deer.
