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.
The non-selective herbicide kills weeds top to bottom, roots included, in a matter of minutes. Simply spray directly on weeds until foliage is wet, and let the Natria work its deadly magic.
This salt is one of the most widely used herbicides worldwide. [6] It is quick-acting and non-selective, killing green plant tissue on contact. Paraquat is toxic (lethal) to human beings and animals. Paraquat's poisoning and lethality depends on the dose and how the herbicide is absorbed by the body.
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).
Monsanto first developed Roundup in the 1970s. End-users initially used it in a similar way to paraquat and diquat – as a non-selective herbicide. Application of glyphosate-based herbicides to row crops resulted in problems with crop damage and kept them from being widely used for this purpose.
Glufosinate (also known as phosphinothricin and often sold as an ammonium salt) is a naturally occurring broad-spectrum herbicide produced by several species of Streptomyces soil bacteria. Glufosinate is a non-selective, contact herbicide, with some systemic action. [1]
