Mesotrione is a selective herbicide used mainly in maize crops. [1] It is a synthetic compound inspired by the natural substance leptospermone found in the bottlebrush tree Callistemon citrinus . It inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) [ 3 ] and is sold under brand names including Callisto and Tenacity.
Mesotrione was introduced in 2002 and like sulcotrione is a triketone, so it is effective on the same weeds and crops, but is more potent, making it more useful in mixes with other herbicides - an important factor for fully controlling weeds and preventing the development of resistance. It has become the biggest selling member of the HPPD class ...
In the mid-1980s, scientists at Stauffer Chemical Company published patents to benzoyl-substituted cyclohexanediones which led to their product mesotrione. [3] This encouraged workers at Rhône-Poulenc to expand their own research into molecules with the same mode of action as these 4-hydroxyphenylpyruvate dioxygenase inhibitors .
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]
Leptospermone can be synthesized from phloroglucinol by a reaction with 3-methylbutanenitrile (isovaleronitrile) in the presence of a zinc chloride catalyst. . Phloroisovalerone imine is produced which is then alkylated with iodomethane after initial treatment with sodium ethoxide and methanol to produce an intermediate which is treated with aqueous hydrochloric acid resulting in ...
Bentranil is a postemergent herbicide used to control annual weeds in cereal crops, maize, and rice. [1] 11,000 pounds (5,000 kg) of bentranil was used in the US in 1974. [2]
Atrazine is a chlorinated herbicide of the triazine class. [2] It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn), [3] soybean [3] and sugarcane and on turf, such as golf courses and residential lawns.
