Agrostis rossiae, or Ross' bentgrass, is a species of perennial [2] or annual grass [3] that is endemic to the Firehole River drainage and Shoshone Geyser Basin of Yellowstone National Park. [ 4 ] [ 5 ] It is one of 3 endemic plants to the park.
Agrostis scabra is a common species of grass known by the common names hair grass, [2] rough bent, [3] rough bent grass, [2] winter bent grass, [2] and ticklegrass. [4] A tumbleweed , [ 4 ] [ 5 ] it is a bunchgrass native to Asia and much of North America , and widely known elsewhere as an introduced species .
2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
Agrostis canina is a perennial plant, with stolons but no rhizomes, and culms which grow to a height of up to 75 centimetres (30 in). [4] It is frequently confused with Agrostis vinealis (formerly treated as a subspecies or variety of A. canina ), which grows in more upland habitats and has rhizomes rather than stolons.
Agrostis stolonifera (creeping bentgrass, creeping bent, fiorin, spreading bent or carpet bentgrass [3] [4] [5]) is a perennial grass species in the family Poaceae. It is widely used as turf for golf courses .
2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants. It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid. It was widely used in the agricultural industry until being phased out, starting ...
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.
In 1940, his work with indoleacetic acid and naphthaleneacetic acid indicated that "growth substances applied appropriately would kill certain broad-leaved weeds in cereals without harming the crops," [11] [12] though these substances were too expensive and too short-lived in soil due to degradation by microorganisms to be of practical ...
