ALL Barenbrug permanent pasture ryegrass seed is tested for endophyte.
Type of endophyte is stated (e.g. NEA2).
Levels are given for the percentage of seed containing endophyte:
- NEA2, NEA, AR1 or AR37 : 70%+ of seed have stated endophyte
- LE or 'Low endophyte' : a low level of seeds have any endophyte

Endophyte levels in ryegrass seed drop off over time.
On-farm, store seed with novel endophytes in a cool, dry place. Sow seed within one month of purchase.
Commercial ryegrass seed with novel endophyte (e.g. NEA2, AR37) is carefully carried over between seasons using controlled humidity cool storage.

  • Some ryegrass, red clover, lotus and brassica cultivars are tetraploids.
  • Tetraploids have four sets of chromosomes per cell, twice as many as normal diploid plants.
  • Tetraploids usually have bigger darker leaves than diploids.
  • In perennial ryegrass, tetraploids need different management for best performance.
