Description
Technical Field
The invention belongs to the technical field of pesticide herbicides, and particularly relates to a weeding composition containing clethodim and triafamone.
Background
The clethodim is an ACCase inhibitor, is quickly absorbed and transferred by plants after being applied to leaf surfaces, is transferred to a growing point at phloem to inhibit the growth of new buds, and weeds lose green firstly and then change color and die, and are completely died within 2-3 weeks generally. The herbicide is mainly used for preventing and removing gramineous weeds such as barnyard grass, cymbopogon flexuosus, large crabgrass, moleplant seed, green bristlegrass, cudweed and the like in a rice field, and is safe to direct-seeded rice and transplanted rice; but the control effect on broad-leaved weeds and sedge weeds is not ideal.
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. It is mainly absorbed by root system and bud, and has the herbicidal activity of stem and leaf absorption. The herbicide is used before or in early stage after germination, is used for preventing and removing gramineous weeds and broadleaf weeds in paddy fields, and can effectively prevent and remove 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.
Although the cycloprione and the triafamone can prevent and kill weeds in the paddy field, the single components have low comprehensive preventing and killing effect on the total weeds in the paddy field and cannot achieve the aim of weeding because the single components generate drug resistance in the using process, the resistance range is enlarged year by year and the control effect is reduced year by year.
The compounding of the clethodim and the triafamone can expand the weed control spectrum and has obvious synergistic effect; and the compound is high in safety, the using dosage is reduced, the drug use frequency is reduced, the drug application cost is reduced, the weed population migration can be controlled, the drug resistance of weeds is reduced, the agricultural ecological balance is maintained, and the environment is protected, so that the compound of the two is worthy of popularization.
