Abstract
The invention discloses a synergistic herbicide, which consists of effective components and auxiliary materials, wherein the effective components are a mixture of bispyribac-sodium and cyhalofop-butyl, and the weight of the two components is respectively as follows: 1-45% of bispyribac-sodium and 1-45% of cyhalofop-butyl. The paddy field herbicide reduces the mu cost of chemical weeding of the paddy field, relieves the burden of farmers, and can prevent and control the harm of various gramineous weeds and broadleaf weeds in the paddy field only by applying the herbicide once, thereby reducing the mu cost of the paddy field herbicide and improving the weeding effect on malignant weeds in the paddy field. Has good safety to rice after being applied and has wide popularization and application prospect.
Description
Technical field
The present invention relates to agricultural chemicals, particularly a kind of herbicide technology.
Background technology
Two careless ethers: other names of Chinese are called one strange, the salicylic acid Sulfadiazine Compound, and English common name: bispyribac-sodium is a kind of pyrimidine salicylic acid weed killer herbicide.Herbicide effect mechanism: acetolactate synthestase (ALS) inhibitor, work by the biosynthesis that stops branched-chain amino acid.Absorb by cauline leaf and root, and conduct in plant, weeds promptly stop growing, and are then withered.Have than high selectivity, to crop, people, animal and beneficial organism safety, pollution-free substantially to environment.Two careless ethers are mainly used in direct seading rice seedling rear defence and remove annual and perennial weed, the barnyard grass grass is had special efficacy, and (the barnyard grass grass to the 1-7 leaf phase is all effective, the 3-6 leaf phase prevents knowingly following the example of a wrongdoer good), weeds such as car forearm shape grass, barnyard grass grass, junglerice, Aleppo grass, difformed galingale herb, cyperus iria, firefly Lin, purple water amaranth, bacopa monnieri, Commelina communis, Li Micao, big lady's-grass, Sagittaria pygmaea also there is excellent activity.
Cyhalofop-butyl: other names of Chinese are called a thousand pieces of gold, and English common name: cyhalofop-butyl is a kind of aryloxy group phenoxy propionic acid ester herbicide.Belong to the inner sucting conduction type inhibitor, it is the seedling post-treatment agent, its effect characteristics are medicaments after cauline leaf is handled, and are absorbed by grass cutting blade and leaf sheath rapidly, and are transmitted to the top so that whole plant, accumulate meristem zone in plant corpus, suppress acetyl-CoA carboxylase (ACC enzyme), fatty acid is synthesized stop, the growth division of cell can not normally be carried out, film system etc. contains the fat structural deterioration, causes plant death at last.Not only various barnyard grass natural plant heights are imitated, also can prevent and kill off grassy weeds such as moleplant seed, lady's-grass, Paspalum distichum, green foxtail, eleusine indica.And to the paddy rice high safety, the paddy rice of various planting types (as non-irrigated seedling, watery ricenursery, live, rice transplanting, rice transplanting etc.) is used by seedling stage to the shooting stage and can not produce poisoning.Between gramineous plants, has good selectivity.But in recent years, this class weed killer herbicide has also produced certain resistance.
Summary of the invention
The objective of the invention is at above-mentioned weak point, provide that a kind of feature of environmental protection is good, the Synergistic herbicidal agents of broad weed-killing spectrum.
Active ingredient of the present invention is made up of two careless ethers, cyhalofop-butyl.
Raw material weight percentage is two careless ethers 1～45%, cyhalofop-butyl 1～45%, auxiliary agent 2～25%, filler (solvent) 8～96%.
The present invention carries out two careless ethers and cyhalofop-butyl composite; show extremely strong activity of weeding, be applied to agricultural plant chemoproection field, be mainly used in and prevent and kill off paddy field weed; to crops safety; have obvious synergistic effect, enlarged simultaneously and killed the grass spectrum, be used to prevent and kill off paddy field weed; preventive effect is good; do not have cross resistance between the two, be better than two careless ethers, two medicament lists of cyhalofop-butyl usefulness, can reduce farming simultaneously originally.Prove after tested, chemical property of the present invention is stable, synergy is remarkable, enlarged and killed the grass spectrum, controlling object is shown obvious synergistic effect and energy suspension of pesticide resistance generation, be applicable to rice direct seeding field (comprise overlapping and broadcast rice), non-irrigated seedling, watery ricenursery, rice transplanting, rice transplanting etc., reach the purpose of preventing and kill off all kinds of weeds.
The present invention can be made into wetting powder, suspending agent, missible oil or aqueous emulsion.
When the present invention was wetting powder, auxiliary agent was made up of dispersant 1.95～20%, wetting agent 0.05～5%, and percentage is preparation raw material weight percentage.Dispersant adopts lignosulfonates, NNO, draws back a kind of or any two kinds of mixtures or three kinds of mixtures in the powder, and wherein lignosulfonates are selected calcium lignosulfonate or sodium lignin sulfonate for use; Wetting agent adopts alkyl benzene calcium sulfonate or sodium alkyl benzene sulfonate.That filler adopts is silica-based, a kind of or mixture in the precipitated calcium carbonate, white carbon black; Silica-based potter's clay, kaolin, the diatomite etc. selected for use.
When the present invention was suspending agent, auxiliary agent was made up of dispersion moisture agent 1～15%, antifreeze 0.4～3%, thickener 0.5～5%, defoamer 0.1～2%, and percentage is preparation raw material weight percentage.Dispersion moisture agent in the suspending agent adopts polyoxyethylene triphenyl phosphorus hydrochlorate, alkylnaphthalene sulfonate, a kind of or mixture in the alkylphenol polyoxyethylene; Antifreeze adopts alcohols, selects propane diols or glycerine or ethylene glycol for use; Thickener adopts xanthans or aluminium-magnesium silicate; Defoamer adopts silicone defoaming agent; Filler adopts water, a kind of or mixture in the white carbon black.
When the present invention was missible oil, the auxiliary agent of missible oil was a surfactant, comprised 10～80% solvent in the filler, and above percentage is preparation raw material weight percentage.Surfactant in the missible oil is based on the multiple model anionic emulsifier of alkyl benzene calcium sulfonate or based on a kind of or mixture in the anionic emulsifier monomer of the nonionic emulsifier of 600# series, BY series, NP series or phosphate-type surfactant, new EO and PO block nonionic emulsifier monomer and modification; It is main a kind of or mixture that solvent adopts light aromatic hydrocarbon such as dimethylbenzene or heavy aromatic hydrocarbon.
When the present invention is aqueous emulsion, comprise in surfactant 8～15%, defoamer 1～2%, antifreeze 0～5%, thickener 1～3%, the filler comprising cosolvent 0～20%, deionized water, more than each percentage be preparation raw material weight percentage.Surfactant in the aqueous emulsion is with the polyoxyethylene alkylphenol class, polyoxyethylene alkaryl phenols, polyoxyethylene aliphatic alcohols, sorb (candy) alkoxide, a kind of or mixtures of emulsifier such as EO/PO induced by alkyl hydroxybenzene and EO/PO castor-oil plant oils; Thickener has gelatin, Sodium Tvlose, hydroxyethylcellulose, modified starch, xanthans, sodium alginate and polyvinyl alcohol etc.; Defoamer has organic matter class, silica-based, silicone based etc.; Antifreeze has glycerine, ethylene glycol, urea etc.; It is main a kind of or mixture that cosolvent adopts light aromatic hydrocarbon such as dimethylbenzene or heavy aromatic hydrocarbon or alcohol or N-Methyl pyrrolidone.
