Butafenacil is the ISO common name [3] for an organic compound of the pyrimidinedione chemical class used as an herbicide. It acts by inhibiting the enzyme protoporphyrinogen oxidase to control broadleaf and some grass weeds in crops including cereals and canola .
The University of Hertfordshire maintains a database of the chemical and biological properties of these materials, [2] including their brand names and the countries and dates where and when they have been introduced. [3] The industry-sponsored Herbicide Resistance Action Committee (HRAC) advises on the use of herbicides in crop protection and ...
Second-year plants develop racemes of flowers each containing 5–20 flowers. [4] The flowers are typically 5-merous with large, white petals and light green sepals, borne in mid-spring. [ 5 ] Second-year plants are also capable of growing the fruit which gives the plant's common name, the blackberry .
Triclopyr is a selective weedkiller used to control dicotyledonous weeds (i.e. broadleaf plants) while leaving monocotyledonous plants (mostly bulbs, grasses and conifers) unaffected, [2] or to control rust fungus on soybean crops.
Fenoprop, also called 2,4,5-TP, is the organic compound 2-(2,4,5-trichlorophenoxy)propionic acid. [2] It is a phenoxy herbicide and a plant growth regulator, an analog of 2,4,5-T in which the latter's acetic acid sidechain is replaced with a propionate group (with an extra CH 3).
Plastoquinone is, in turn, a critical co-factor in the formation of carotenoids, which protect chlorophyll in plants from being destroyed by sunlight. [4] This class of herbicides represents one of the last discoveries of a new herbicide mode of action in the wave of discovery that ended in late 1990s. [3] [7]
Hexazinone is an organic compound that is used as a broad spectrum herbicide. It is a colorless solid. It exhibits some solubility in water but is highly soluble in most organic solvents except alkanes. A member of the triazine class herbicides, it is manufactured by DuPont and sold under the trade name Velpar. [1]
Chlorsulfuron is an ALS (acetolactate synthase) inhibitor herbicide, and is a sulfonylurea compound. [3] [4] It was discovered by George Levitt in February 1976 while working at DuPont, which was the patent assignee. [5] [6] [7]
