Background
Fomesalamine, the common name triafamone in English, has the development code AE1887196, BSC-BX60309 and CAS accession number 874195-61-6, and is an acetolactate synthase (ALS) inhibitor which inhibits cell division and plant growth by preventing the biosynthesis of valine, leucine and isoleucine. The root system and the bud are mainly absorbed, and the weeding activity is absorbed by the stem leaves. The herbicide is used before or after emergence for preventing and killing gramineous weeds, nutgrass flatsedge and broadleaf weeds in paddy fields. Can effectively prevent and kill barnyard grass, paspalum distichum, scirpus planiculmis, cyperus annuus and the like; it also has good inhibiting effect on broad-leaved weeds such as ludwigia prostrata, arrowhead, eclipta prostrata, potamogeton indica, etc., and perennial sedge. Can be mixed with other herbicides to expand the weed control spectrum.
Anilofos, a herbicide that affects cell division, is a cell growth and division inhibitor. Inhibit long chain fatty acid synthesis, thereby affecting cell division. It is absorbed mainly by plant buds and underground stem to inhibit cell division and elongation. Has good effect on the weeds which are germinated. Can be used for transplanting in rice field to effectively prevent and kill annual gramineous weeds and nutgrass flatsedge, such as barnyard grass, cyperus rotundus, sedge opposite, monochoria vaginalis, fimbristylis dichotoma, petaloid flower, beefwood, and Equisetum arvense. Is a cell generation and division inhibitor and has low toxicity. 4-10 days after transplanting rice, the pesticide is applied before 2 leaves of gramineous weeds in the first-heart stage. Can be used in rice transplanting field for preventing and killing gramineous weeds such as barnyard grass and moleplant seed before trefoil stage.
