Dimethenamid is a widely used herbicide belonging to the chloroacetamide class (group 15). Group 15 herbicides inhibit synthesis of certain long-chain fatty acids, thus reducing plant growth. [ 3 ] In 2001, about 7 million pounds (3,200 t) of dimethenamid were used in the United States. [ 4 ]
Metolachlor is a popular herbicide in the United States. [3] As originally formulated metolachlor was applied as a racemate , a 1:1 mixture of the ( S )- and ( R )-stereoisomers. The ( R )-enantiomer is less active, and modern production methods afford a higher concentration of S-metolachlor, thus current application rates are far lower than ...
Enlist Duo is an herbicide that contains the choline form of 2,4-Dichlorophenoxyacetic acid (2,4-D) and glyphosate plus an unknown number of unlisted ingredients. Dow added chemicals to the mixture in what it termed "Colex-D technology". [5] 2,4-D is one of the most widely used herbicides in the world.
Ethofumesate is a Group J (Australia), K3 (Global), Group 15 (numeric), resistance class herbicide. [3] In soil is ethofumesate biodegraded by soil's microörganisms. In soils with over 1% organic matter content, ethofumesate doesn't leach. The halflife in soil is 5-14 weeks, and residual herbicide activity can last four to eight months. [1]
In the United States as of 2014, atrazine was the second-most widely used herbicide after glyphosate, [16] with 76 million pounds (34 thousand metric tons) of it applied each year, [19] [20] nearly identical to its usage in 1974, of 76.8 million pounds. [21] Atrazine continues to be one of the most widely used herbicides in Australian ...
The herbicide is usually applied to the soil in which the crop is growing, before the emergence of the weeds. [1] In the US it is applied almost exclusively in corn with annual use in 2018 about 600,000 pounds (270,000 kg). [12] The compound is often formulated in combination with the herbicide safener, cyprosulfamide. [13]
Acetochlor is an herbicide developed by Monsanto Company and Zeneca. It is a member of the class of herbicides known as chloroacetanilides. Its mode of action is elongase inhibition, and inhibition of geranylgeranyl pyrophosphate (GGPP) cyclization enzymes, part of the gibberellin pathway. It carries high risks of environmental contamination. [2]
Diflufenican (sometimes called DFF) is a herbicide used to control weeds including wild radish and wild turnip weeds or suppress capeweed, crassula, marshmallow or shepherd's purse, in clover pasture, lupins, lentils or field peas.
