When using herbicides to suppress winter annual grasses the two most important factors that influence success are application timing and residual soil activity. Application timing is split into three main categories: pre-emergence in the fall before Bromus tectorum germinates, early post-emergence in early spring when B. tectorum is a seedling ...
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 .
Lolium multiflorum (Italian rye-grass, [2] annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. [3] It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. [4] [5] It is also grown as an ornamental grass.

A national assessment of wildfire risk in the United States based on GACG identified regions (with the slight modification of combining Southern and Northern California, and the West and East Basin); indicate that California (50.22% risk) and the Southern Area (15.53% risk) are the geographic areas with the highest wildfire risk.

[2] [3] It is often called ryegrass, but this term is sometimes used to refer to grasses in other genera. They are characterized by bunch-like growth habits. Lolium is native to Europe , Asia and northern Africa , as well as being cultivated and naturalized in Australia , the Americas , and various oceanic islands.
Other land management activities can affect the effectiveness of post fire seeding. Grazing seeded burned areas exacerbates the problem of non-native annual grass invasions, even when conducted after a two-year hiatus. Historic post logging seed treatments had a significant influence on the effectiveness of post Rodeo-Chediski fire seeding.
