What is an endophyte in ryegrass?
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 a place to live and reproduce. Endophytes produce a number of chemical compounds.
Is rye grass endophyte free?
Most turf varieties, and some forage varieties, of tall fescue and perennial ryegrass are infected with a fungal endophyte. These endophytes produce bioactive compounds that enhance plant performance.
What is endophyte in fescue?
“endophyte” means internal fungus; it grows inside fescue plants. soon thereafter it was learned that this endophyte can produce toxins (specifically, ergot alkaloids) that can have profound negative effects on grazing animals. however, the endophyte has positive effects on the grass itself.

What is low endophyte?
Low endophyte (LE) implies low or nil endophyte infection levels in the seed and its use is best suited to areas of low insect predation generally associated with high summer moisture.
What does endophyte-free mean?
TE fescue produces toxic alkaloids that cause animal disorders. EF (Endophyte-Free) Fescue. This term refers to tall fescue that does not contain an endophyte. If there is no endophyte, then there will be no endophyte-related toxic alkaloid production, and thus endophyte-free fescue is non-toxic.
Is creeping red fescue endophyte-free?
(A) Endophyte-free strong creeping red fescue (E-), Rose City (RC), and Delaware (DE) isolates of Epichloë festucae fungal endophyte-infected strong creeping red fescue plants under control conditions and after 28 d of heat, drought, and heat + drought stress conditions.
How do you test for endophytes?
It is critical to know the level of endophyte. How do we test for the endophyte? This time of year, it is best to test the growing tillers. The testing process involves clipping each tiller at the soil surface, where it meets the root, then sending it to a good lab.
Can fescue be tested for endophyte?
