Researchers are making gains towards the identification of resistant cultivars as evidenced by the finding that variation in genetic linkage groups 1, 4, and 6 accounted for over 43% of resistance among Italian rye grass. [9] A 1987 study found evidence of a possible biocontrol strategy for bacterial wilt of turf grass.

Annual ryegrass toxicity (ARGT) is the poisoning of livestock from toxin contained in bacterially infected annual ryegrass (Lolium rigidum). The toxin is produced by the bacterium Rathayibacter toxicus (formerly Clavibacter toxicus ), which is carried into the ryegrass by the nematode Anguina funesta .
Pregnancy tests are not accurate until 1–2 weeks after ovulation. Knowing an estimated date of ovulation can prevent a woman from getting false negative results due to testing too early. Also, 18 consecutive days of elevated temperatures means a woman is almost certainly pregnant. [61]

[1] It is a native of southern Europe, northern Africa, the Middle East and the Indian subcontinent and is grown as a forage crop, particularly in Australia ...
It is also known as timothy-grass, meadow cat's-tail or common cat's tail. [3] It is a member of the genus Phleum , consisting of about 15 species of annual and perennial grasses.
