Mesotrione inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD). [3] It is an extremely potent inhibitor of HPPD in laboratory tests using the plant Arabidopsis thaliana, with a K i value of about 10 pM. [6] In plants, HPPD is necessary for the biosynthesis of tocopherols and of plastoquinone, which is essential to carotenoid production
4-Hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors (HPPD inhibitors) are a class of herbicides that prevent growth in plants by blocking 4-Hydroxyphenylpyruvate dioxygenase, an enzyme in plants that breaks down the amino acid tyrosine into molecules that are then used by plants to create other molecules that plants need.
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 ...
Isoxaflutole was first marketed by Rhône-Poulenc in 1996. It controls weeds which are important in crops including corn and sugarcane. [5] [9] [10] These include broad-leaved-weeds from Amaranthus, Datura stramonium and ragweed species and annual grass weeds of Alopecurus, Eriochloa and Panicum species.
A grafted plant consists of two parts: first rootstock, which is the lower part of the plant that comprises roots and the lowest part of the shoot; second, the branches and primary stem, which consists of the upper and main part of the shoot which gradually develops into a fully nourished plant.

Her seed portraits of celebrities were exhibited in the strictly defined "Crop art" category at the Minnesota State Fair beginning in 1966. Rules for entry of Crop art allow "only seeds from Minnesota-grown farm crops or cultivated garden flowers, fruits, and vegetables" with no wild plant seeds permitted.
