What is it about?
The influence of various weed management measures was investigated regarding glyphosate resistance and endophyte infection in Italian ryegrass on paddy levees where glyphosate-resistant individuals were dominant. Endophytes often confer benefits to their host grasses. Therefore, it is necessary to check for endophyte infection when devising measures for controlling invasive host grasses.

Why is it important?
There was a significant relationship between the endophyte infection frequency in the seeds and glyphosate resistance in the seedlings that had been grown from the same populations. The results indicate that where glyphosate herbicides are frequently used, selection for glyphosate-resistant Italian ryegrass occurs, and along with this, the frequency of endophyte infection also increases.
Perspectives
There has been very little research on evaluation of weed character after management. This paper shown that weed management influence the character of glyphosate-resistant Italian ryegrass such as glyphosate resistance and endophyte infection. Therefore, optimal management options for this weed should include monitoring both the characters.
