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.

The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others.
A Film coating, a layer of thin film applied to the seed typically less than 10% of the mass of the original seed. Encrustment, where the applied material is typically 100%–500% of the original seed mass, but the shape is still discernible. Pellet, where the applied material is so thick that the seed's original shape is not discernible.
The model proposes that auxin, a plant growth hormone, is synthesized in the coleoptile tip, which senses light or gravity and will send the auxin down the appropriate side of the shoot. This causes asymmetric growth of one side of the plant. As a result, the plant shoot will begin to bend toward a light source or toward the surface. [3]
