The endophyte experts

 

With over 25 years of experience & purpose build cold storage facilities to help maintain live endophyte percentages; DLF Seeds are proud to be Australia’s leading experts in ryegrass endophyte. 

  • Featured ryegrass endophytes: AR128, AR37, AR1 and Endo5 endophytes
  • Featured tall fescue endophytes: MaxP® endophyte

How an endophyte protects your pasture: An endophyte is a fungus found naturally in many grass species, including ryegrass. It provides the plant with protection from insects, and in return the plant provides the endophyte with a place to live and reproduce.

Endophyte DLF Seeds

Benefits of ryegrass with AR37 endophyte 

  • Provides the best proven balance of pasture production and persistence
  • Higher tiller density over time
  • Assists with post drought recovery and improves agronomic performance
  • Provides stronger control of more insect pests compared to ryegrass cultivars containing AR1 or standard endophyte (SE)
  • May produce greater carcass weight per hectare compared to ryegrass cultivars containing SE
  • Helps to provide a greater return on investment
  • Increased total dry matter production compared to ryegrass cultivars containing AR1 or nil endophyte
  • Has no Ergovaline which increase milk production compared to endophytes containing high Ergovaline levels
  • Increased sheep performance compared to ryegrass cultivars containing SE
  • Low incidence of dags in sheep (similar to that of cultivars containing AR1 endophyte)

Some AR37 endophytic forage seed varieties

Base Ar37 Base AR37 tetraploid perennial ryegrass The Australian bred perennial ryegrass for Australian conditions with proven performance across wet, dry and neutral weather patterns within dairy, sheep and beef operations. Sow for high quality pasture seed with premium protection from insects with AR37 endophyte.
Vast AR37 Vast AR37 tetraploid perennial ryegrass Vast AR37 is a tetraploid with diploid level density and excellent rust tolerance for improved summer and autumn palatability. Quality pasture with the latest heading date of a perennial ryegrass on the market (+36 days).
Anvil AR37 DLF Seeds Anvil AR37 tetraploid hybrid ryegrass NEW Anvil AR37 is an elite tetraploid hybrid ryegrass with a robust, palatable leaf, impressive density and AR37 insect protection. Features a late heading date for exceptional summer performance.

Coming soon: New AR128 endophyte

What is AR128 Novel endophyte?

In almost every way from an on-farm point of view, it’s just the same as AR37. Like AR37 endophyte, AR128 is a selected novel endophyte producing epoxy-janthitrem alkaloids, which offers similar pest protection and risk of ryegrass staggers. (Based on current information available to the end of May 2025).

When will AR128 endophyte be available?

Mohaka AR128 tetraploid hybrid ryegrass will be available ex harvest in Autumn 2026. The remainder of the perennial and hybrid ryegrass portfolio will transition to AR128 from AR37 over the next 3-5 years.

If AR128 is the same as AR37, why replace AR37?

  • AR128 brings benefits to the endophytic seed supply chain.
  • For an endophyte to be effective on farm, at least 70% of the seed needs to contain a live endophyte.
  • It’s a minimum standard DLF Seeds adheres to when selling our cultivars with endophyte.
  • Anything lower than this level can potentially affect the total pasture’s ability to be protected from insect pests.
  • AR128 is a more robust endophyte for both transmission and storage than AR37, hence more reliability in delivering seed to the market.

Endo5 endophyte

Good pest control and no known risk of ryegrass staggers

About Endo5 endophyte

Pests controlled with Endo5: Argentine Stem Weevil Larvae, Black Beetle, Argentine Stem Weevil Larvae, Root Aphid (moderate control) and Pasture Mealy Bug (Comparatively, AR37 has demonstrated stronger control of insects). 

  • Available in: Reward Endo5 tetraploid perennial ryegrass
  • Suitable for: Beef, sheep and dairy
  • Limitations of ryegrass with Endo5 endophyte: May produce lower animal performance levels over summer/autumn compared to ryegrass cultivars containing AR1 or nil endophyte. 

Benefits of ryegrass with Endo5 endophyte 

  • Contains no Lolitrem B, the main cause of ryegrass staggers
  • Produces less Ergovaline for increased milk production compared to endophytes containing high levels of Ergovaline (Standard endophyte (SE) contains high levels of Ergovaline)
  • Increased persistence compared to AR1 endophyte
  • Pest and insect protection better than AR1 endophyte

AR1 endophyte

A novel endophyte option with high animal performance and no known animal health issues

About AR1 endophyte

Pests controlled with AR1: Argentine Stem Weevil Larvae and Pasture Mealy Bug 

  • Available in: Reason diploid perennial ryegrass and Three60 diploid perennial ryegrass
  • Suitable for: Beef, sheep, dairy, horse and deer
  • Limitations of ryegrass with AR1 endophyte: Has demonstrated poorer persistence in areas with major insect pest pressure from Black Beetle and Root Aphid. AR1 can be overgrazed, resulting in more stress on the plant which may affect long term pasture persistence

Benefits of ryegrass with AR1 endophyte 

  • Delivers excellent animal performance
  • Provides a moderate range of insect protection
  • Increase in milk production compared to ryegrass cultivars containing Standard endophyte (SE) (in areas where ryegrass persists)

AR1 endophytic forage seed varieties

Reason DLF Seeds Reason AR1 diploid perennial ryegrass New high performance diploid with industry leading autumn growth and a +3 heading date.
Three60 Three60 AR1 diploid perennial ryegrass Thee60 is a NEW, late heading diploid providing outstanding autumn performance with late spring quality. Sow pasture seed for quality stock feed and excellent crown rust tolerance.
