In 1990 sulcotrione was introduced for post- emergence weed control in corn. Isoxaflutole opened the market more broadly for HPPD inhibitors when it was introduced in 1996 for corn and sugarcane, and for use as a pre-emergence herbicide that could control broadleaf weeds as did sulcotrione, but also additional grass weeds.
The genes contained in these seeds are patented. Such crops allow farmers to use glyphosate as a post-emergence herbicide against most broadleaf and cereal weeds. The health impacts of the product as well as its effects on the environment have been at the center of substantial legal and scientific controversies.
Trifluralin is a common pre-emergent selective herbicide, a dinitroaniline.With about 14 million pounds (6,400 t) used in the United States in 2001, [3] and 3–7 million pounds (1,400–3,200 t) in 2012, [4] it is one of the most widely used herbicides.
Bromoxynil is an organic compound with the formula HOBr 2 C 6 H 2 CN. It is classified as a nitrile herbicide, and as such sold under many trade names.It is a white solid. It works by inhibiting photosynthesis.
As described in the BASF patent, the key step in the preparation of saflufenacil involved the reaction between a substituted aniline and an oxazinone. 2-chloro-4-fluoro-5-aminobenzoic acid and 2-dimethylamino-4-(trifluoromethyl)-6H-1,3-oxazin-6-one were heated in acetic acid to form the ring systems of the herbicide in over 90% yield, with further standard chemical transformations to generate ...
Bensulide is a selective organophosphate herbicide. It is one of a few organophosphate compounds that are used as an herbicide. Most of the others are used as insecticides. It is used on vegetable crops such as carrots, cucumbers, peppers, and melons and in cotton and turfgrass to control annual grasses such as bluegrass and crabgrass and ...
Pre-emergence herbicides are applied to lawns prior to weed seed germination. Our standard recommendations are Sept. 1-15 for cool season weeds and mid-February to March 1 for warm season weeds.
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 ...
