Using Endophytes in your permanent pasture mixes improves animal health providing better animal performance, more palatable pasture, and easier pasture management.
Endophyte is a fungus (called Neotyphodium lolii) that greatly affects animal health and performance. Endophyte is found only in ryegrass and tall fescue. It lives completely within the plant and is only visible under a microscope. Endophyte occurs naturally, and is found in many old pastures.
There are many different types of Endophyte currently available and each varies in persistance, yield, and insect protection. Endophyte protects plants from a range of insects. In dry summer situations ryegrass containing endophyte consistently out-yields and persists better than ryegrass Without endophyte.
Please browse the different the types of ryegrass endophyte below:
The GrubOUT® U2 endophyte is a strain of Neotyphodium uncinatum. It contains a unique set of alkaloids called lolines, which insects don’t like. Use GrubOUT® U2 and enjoy the benefits of better pasture protection against insect pests, improved pasture persistence and superior livestock performance potential. Its benefits include:
If you have any questions on GrubOUT please contact Specialty Seeds.
Without Endophyte gives good animal performance, but reduced insect resistance. Only suitable for summer wet South Island areas.
Low Endophyte grasses provides better animal performance than High Endophyte ones but the downside of this is that it wont persist as well.
High/ Standard Endophyte is still available in some older varieties. It is not recommended because it causes ryegrass staggers, depresses liveweight gains in lambs and reduces milk production in dairy cows. This type of endophyte although persists extremely well in tough conditions.
Ryegrass with AR1 endophyte is a non-staggering endophyte that has excellent animal performance. However, the Peramine does not give good resistance against Black Beetle, and care is needed in areas with high Black Beetle numbers, such as the northern half of the North Island. AR1 endophyte has now been extensively field-tested for animal safety and productivity, and is now available commercially in a number of ryegrass cultivars.
AR1 endophyte in ryegrass offers the following benefits:
These are non-staggering endophytes that provide the equivalent insect protection of AR1, with the additional benefit of resistance to Black Beetle through the presence of low to moderate levels of Ergovaline. AR6 pastures are likely to persist better than AR1 pastures in areas with high Black Beetle numbers, such as the northern North Island.
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. AR37 endophyte in ryegrass offers the following benefits:
Edge is a novel endophyte discovered by DLF Seeds Endophyte Programme. It produces high levels of peramine, a powerful insect deterrent. It does not produce any Lolitrem B, or janthitrems alkaloids. It has a trace of ergovaline. This combination has resulted in a ryegrass endophyte that gives tolerance to black beetle and ASW, but is safe on animals.
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. Endo5 endophyte in ryegrass offers the following benefits:
Happe is a breakthrough technology that many farmers will benefit from. It was discovered in a meadow fescue plant and successfully transferred by DLF scientists into ryegrass plants. Happe produces substances called lolines, which have a powerful effect on many insects. Independent research has proved that Happe provides tolerance to the same insects as Edge, but also to porina. Happe has been tested by independent scientists to confirm that it does not cause ryegrass staggers and does not affect animal performance.
Happe has been tested throughout the country with great success. One of the trials highlighted the advantage of Happe, when it improved production by an average of 21% in five different cultivars from December to May. Happe is currently available in 24 seven and Ansa perennial ryegrasses
NEA2 endophyte is ideally suited to intensive farming systems through all regions of NZ, providing persistent, staggers free pasture with excellent animal performance. Ryegrass with NEA2 gives good control of black beetle, to the same level as AR37. It also provides a level of control of Argentine stem weevil (ASW), pasture mealy bug (provisional rating) and root aphid, higher in the diploid cultivar Trojan than in Bealey.
Please browse the different the types of Tall Fescue endophyte below:
Max P is a novel endophyte for the use in modern tall fescue cultivars. Max P greatly increases tall fescues persistence and production by protecting it from insects. In Canterbury trials yield increases of 25 -39 % have been recorded when comparing Max P with non-endophyte tall fescues. For more information on Max P Tall Fescues please contact Specialty Seeds.
Protek endophyte is a novel tall fescue endophyte that does not produce any animal toxins, and has been tested by independent scientists to confirm it has no effect on animals. Protek produces lolines, which have a strong effect on many insect species. The lolines are present in both plant material above ground and in roots.
Insects that Protek works against include, Grass grub, Black beetle, Porina, Argentine stem weevil, Root aphid and Pasture mealy bug.
