Imazapyr is a non-selective herbicide used for the control of a broad range of weeds including terrestrial annual and perennial grasses and broadleaved herbs, woody species, and riparian and emergent aquatic species. [1] It is used to control annual and perennial grass and broadleaved weeds, brush, vines and many deciduous trees.
"If you are going to use a control product, whether it be organic or chemical-based, fall is the best time of year to control perennial weeds," says John Cannon, NaturaLawn of America’s ...
When 2,4-D was commercially released in 1946, it became the first successful selective herbicide, triggering a worldwide revolution in agricultural output. It allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crops, because it kills dicots (broadleaf plants), but not most monocots (grasses).
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.
It is selective for plants with broad leaves, and this includes most deciduous trees. Clovers are tolerant at moderate application levels. It is currently classified as a restricted use pesticide in the United States : its use is mapped by the US Geological Survey , whose data show consistent use from 1992, with a small recent decline in the ...
Imazaquin is a non-volatile chemical leading to limited movement into soil that eventually breaks down within 4–6 months. The chemical breaks down microbially and is slowly reduced to carbon dioxide and metabolites.
Picloram can be sprayed on foliage, injected into plants, applied to cut surfaces, or placed at the base of the plant where it will leach to the roots. Once absorbed by the foliage, stem, or roots, picloram is transported throughout the plant. Herbicides containing picloram are sold under a variety of brand names.
The triketone herbicides were found to be effective on a wide range of commercially-important weed species and to have both pre- and post-emergence activity. [9] Mesotrione was chosen for development (by Zeneca Agrochemicals under the code number ZA1296) because it controls a wide range of broad-leaved weeds that compete with maize and can also suppress some annual grass weeds that may be ...
