The weeding composition can be used for preventing and removing annual weeds in the paddy field and has obvious synergistic effect.
Description
Technical Field
The invention belongs to the field of herbicides, and particularly relates to a weeding composition containing metamifop, halosulfuron-methyl and butachlor and application thereof.
Background
Metamifop belongs to aryloxy phenoxy propionate herbicides, has an action mechanism of an acetyl coenzyme A carboxylase (ACCase) inhibitor, can inhibit the synthesis of plant fatty acid, and is used for preventing and killing various gramineous weeds such as large crabgrass, moleplant seeds, large crabgrass and the like in the stem and leaf treatment of a paddy field. Halosulfuron-methyl is a sulfonylurea herbicide, is an inhibitor of acetolactate synthase (ALS enzyme), and the effective components can diffuse rapidly in water, and are absorbed and transferred to the root and leaf of weeds, so as to hinder the biosynthesis of amino acid, lysine and isoleucine and prevent the division and growth of cells. The growth function of the sensitive weeds is hindered, young tissues are yellowed early to inhibit the growth of leaves, and the growth and necrosis of roots are hindered, so that the sensitive weeds are mainly used for preventing and killing broad leaf weeds and cyperaceae weeds. Butachlor is an amide selective preemergence herbicide and can be absorbed by the sprouts and the roots of weeds. Is used for preventing and killing large crabgrass, part of broadleaf weeds, boehmeria, monochoria vaginalis and annual grassy weeds in paddy fields.
Pesticide registration number PD20190187 discloses a 20% oxazolylamine-chloropyrimido dispersible oil suspending agent, and the two can be used in a mixed manner to effectively prevent and kill annual weeds in paddy fields (direct seeding).
CN201910163758 discloses a herbicidal composition, the active component of which is composed of a component a and a component B, wherein the component a is halosulfuron-methyl, and the component B is butachlor; wherein the weight ratio of the component A to the component B is 1:1-1: 100.
CN201510780057 discloses a herbicidal composition, the active components of which are composed of halosulfuron-methyl and metamifop; the weight ratio of the halosulfuron-methyl to the metamifop is 100:1-1: 100.
According to the previous investigation of the prior art, no related literature report of compounding metamifop, halosulfuron-methyl and butachlor exists in the prior art. In addition, as known in the art, the single use of the composition for a long time easily causes the drug resistance of weeds, pollutes the environment, and the research and development of a synergistic composition which can improve the weeding effect and reduce the application dosage of active ingredients is the key point of the research and development of a plurality of pesticide companies in China.
