The invention discloses a kind of Herbicidal composition for paddy fields and its application, it is related to technical field of pesticide combination.Each component includes by weight percentage in described Herbicidal composition for paddy fields：Active ingredient 10~60%, pesticidal preparations auxiliary element 40~90%, wherein the first active ingredient is chlorine fluorine pyridine ester, and second active ingredient is any one in cyhalofop-butyl, metamifops, and the first active ingredient is with the weight ratio of second active ingredient（1:10）~（10:1）.The present invention can be significantly expanded herbicide controlling spectrum, improve the overall preventive effect to weeds in paddy field.Meanwhile, said composition is good to Security of rice, is a kind of extraordinary newtype drug combination for preventing and kill off rice terrace annual grassy weeds.
Description
Technical field
The invention belongs to agrochemicals field, problem is prevented and kill off for rice terrace annual grassy weeds is solved more particularly, to one kind
Herbicidal combinations.
Background technology
Chlorine fluorine pyridine ester (Florpyrauxifen) belongs to pyridines synthetic hormone class herbicide, to acetolactate synthestase
(ALS) inhibitor, acetyl-CoA carboxylase inhibitor (ACCase) inhibitor, p-hydroxyphenypyruvate dioxydenase
(HPPD) weeds of the generation such as inhibitor, propanil, clopyralid, glyphosate, triazine herbicide resistance have extraordinary
Activity, certain activity of weeding is respectively provided with to grass family, broad leaved weed, sedge weed.
Cyhalofop-butyl (Cyhalofop-butyl) belongs to aryloxyphenoxypropionic class herbicide, and the mechanism of action is acetyl
CoA carboxylase inhibitor, synthesizes aliphatic acid and stops, and the growth division of cell can not be normally carried out, the knot containing fat such as membranous system
Structure is destroyed, and finally results in Plant death.It is efficient to moleplant seed to paddy rice high safety, there is certain preventive effect to low age barnyard grass, but
It is undesirable to cyhalofop-butyl resistant biotypes grass family effect.
Metamifop (metamifop) belongs to aromatic oxygen-phenoxy group propionates class herbicide, and its mechanism of action is to suppress second
Acyl coenzyme A carboxylation enzymatic synthesis, synthesizes aliphatic acid and stops, and the growth division of cell can not be normally carried out, the knot containing fat such as membranous system
Structure is destroyed, and finally results in Plant death.To rice safety, have to grassy weed such as barnyard grass, moleplant seed, lady's-grass, eleusine indica
There is good activity.
There is different degrees of defect in the herbicide kind containing single-activity component, on control of weeds such as after continuous use
Weeds easily develop immunity to drugs, and herbicide controlling spectrum narrows, the problems such as cause environmental pollution.
Rationally compounding is to improve preventive effect, expand herbicide controlling spectrum, widen use time to herbicide, delays shift of weed community
Speed, reduce that agricultural chemicals is single to use brought resistance risk, mitigate the pollution to environment, reduce use cost and mitigation removed
A kind of effective ways of careless agent residual.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides that a kind of, toxicity higher to crop safety is low, residual less,
Broad weed-killing spectrum, the Herbicidal combinations that can effectively delay herbicide resistance, the present invention solve the technical side that its technical problem is used
Case is：
Described Herbicidal composition for paddy fields, it is characterised in that each component includes by weight percentage in described herbicide：
Active ingredient 10~60%, wherein pesticidal preparations auxiliary element 40~90%, the first active ingredient are chlorine fluorine pyridine ester, second
Kind of active ingredient is any one in cyhalofop-butyl, metamifops, the first active ingredient and second active ingredient
Weight ratio is (1:10)~(10:1).
Further, Herbicidal composition for paddy fields of the present invention, it is characterised in that described Herbicidal combinations formulation is
Dispersible oil-suspending agent, missible oil, aqueous emulsion etc..
Further, Herbicidal composition for paddy fields of the present invention, it is characterised in that described Herbicidal combinations formulation is auxiliary
Furtherance is divided into carrier, surfactant etc..
Further, the carrier in Herbicidal composition for paddy fields of the present invention is water, soybean oil, methyl oleate, methyl
One or more in naphthalene higher aliphatic hydrocarbon ils, aromatic hydrocarbons S-150 solvent naphthas etc..
Further, the surfactant in Herbicidal composition for paddy fields of the present invention is selected from DBSA
Calcium, lignosulfonates, styrylphenol polyoxyethylene ether, alkylaryl polyoxyethylene poly-oxygen propylene aether, polyoxyethylene gather
One or more in oxypropylene block copolymer, APES phosphate etc..
Further, Herbicidal composition for paddy fields of the present invention, it is characterised in that described Herbicidal composition for paddy fields can
For preventing and kill off rice terrace annual grassy weeds.
The frequency of use and usage amount of Herbicidal combinations of the invention with plant growth, weeds occur, Changes in weather and
There is a small amount of change, the purpose of effective preventing and treating can be reached by using appropriate dosage.
The first active ingredient of its active component of Herbicidal composition for paddy fields of the present invention is chlorine fluorine pyridine ester and second
Common use after active ingredient cyhalofop-butyl Huo metamifops compounding is planted, with notable synergistic effect, is overcome containing single work
Property component herbicidal performance it is not enough, while the generation of herbicide resistance can be delayed, reduce production cost and use cost, expand herbicide
Spectrum, can effectively prevent and kill off rice terrace annual grassy weeds, its have efficiently, low toxicity, low-residual, low cost many advantages, such as, be one kind
Novel rice field herbicidal.
The agricultural chemicals such as surfactant used and carrier auxiliary element belongs to environmentally friendly type in Herbicidal combinations of the invention, low
Poison, low-residual, to rice safety, will not produce murder by poisoning to crop, fishes and shrimps and water body in use.
