AR37 endophyte has been shown to provide superior resistance to a wider range of insects than either standard endophyte (SE) or AR1 endophyte.
These ratings are indicative and may vary slightly between cultivars. If Argentine Stem Weevil larvae or Black Beetle are present at sowing, an appropriate seed treatment is recommended to improve insect control during establishment. The ratings in this table are based in part on glasshouse studies where test plants are 100% infected with endophyte, whereas commercial seed must meet minimum standards of 70% of seeds infected. The tables were compiled by AgResearch, Agricom, Agriseeds, Grasslanz, DairyNZ and PGG Wrightson Seeds.
