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 ]
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]
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 ...
This is a list of herbicides. These are chemical compounds which have been registered as herbicides . The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [ 1 ]
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]
The Herbicide Resistance Action Committee (HRAC) classifies herbicides by their mode of action (MoA) to provide a uniform way for farmers and growers to identify the agents they use and better manage pesticide resistance around the world. [1] [2] It is run by CropLife International [3] in conjunction with the Weed Science Society of America ...
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 activity of the 2-chloro-4-nitro analog was an outlier, and it was theorized that perhaps the nitro group was being reduced in vivo. The 4-methylsulfonyl group was then prepared to test this hypothesis, and what was to become the commercial herbicide Mikado (II) was prepared. The prospect of improving the biological activity with new ...
