Abstract
An agricultural pesticidal and fungicidal combination containing pymetrozine and epoxiconazole consists of pymetrozine, epoxiconazole, auxiliary and excipient, the weight ratio of the pymetrozine to the epoxiconazole is 1:80 to 80:1, and according to percentage by weight, the content of each component in the combination is as follows: 1 to 80 percent of pymetrozine, 1 to 80 percent of epoxiconazole, 1 to 30 percent of auxiliary and the balance of excipient. The agricultural pesticidal and fungicidal combination can effectively control a variety of diseases and insect pests on paddy rice, wheat, peanut, banana and the like, solves the problem that the cost of simultaneously controlling insect pests and diseases is high, and has the advantages of broad control spectrum, slow resistance development, remarkable synergistic effect and low control cost.
Description
Technical field
The present invention relates to technical field of pesticide, specifically a kind of insecticidal bactericide composition that contains pymetrozine and epoxiconazole.
Background technology
Pymetrozine (Pymetrozine), chemical name: 4,5-dihydro-6-methyl-4-(the 3-pyridine methylene is amino)-1,2,4-3 (2H)-ketone, chemical structural formula is:
Pymetrozine has action of contace poison to insect, also has simultaneously systemic activity, can also can therefore both can be used as foliar spray at phloem transport in the xylem transporting in plant corpus, also can be used for soil treatment.Because its good transporting characteristic, the branches and leaves that newly grow after the cauline leaf spraying also can be effectively protected.Pymetrozine can be used for preventing and treating most of homoptera pest, and especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect are applicable to the multiple field crops such as vegetables, paddy rice, cotton, fruit tree.
Epoxiconazole (Epoxiconazole), chemical name: (2RS, 3SR)-3-(2-chlorphenyl)-2-(4-fluorophenyl)-2-[(1H1,2,4-triazol-1-yl) methyl] oxirane, chemical structural formula is:
Epoxiconazole is a kind of interior absorption triazole bactericidal agent, its active component epoxiconazole suppresses the synthetic of germ ergosterol, hinder the formation of germ cell wall, and the epoxiconazole molecule has powerful compatibility to a kind of fungal enzyme (14-dencthylase), compare with at present known bactericide, more establishment germ fungal pathogens.Epoxiconazole can improve all fourth matter enzymic activitys of crop, causes the contraction of fungi haustorium, suppresses germ and invades, and this is epoxiconazole unique characteristic in all triazole type products.Epoxiconazole has good preventive effect to diseases such as the anthracnose on leaf spot, powdery mildew, rust and the grape on the crops such as banana, green onion garlic, celery, Kidney bean, melon, asparagus, peanut, beet, white rots.
For the extermination of disease and insect pest that easily produces resistance on the agricultural, the use mechanism of action is different, the different pesticide species of control spectrum is mixed is a kind of selection of the best.If reasonable mixture ratio then can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose, enlarge agricultural control spectrum.
At present, the insecticide that contains pymetrozine can only pest control, and the bactericide that contains epoxiconazole can only be prevented and treated disease, but large Tanaka's disease and insect pest often occur simultaneously, when damage by disease and insect is all serious, the means that the peasant often takes are for buying simultaneously pesticide product and bactericide product, be mixed in the control of spraying in the sprayer, although this mode is disease and pest control preferably, but cost accounting is higher, and part bactericide and insecticide are owing to reasons such as chemical reactions, and the together use that is not suitable for being mixed, and the improper degradation problem under the control efficiency that easily causes is mixed.
Summary of the invention
The objective of the invention is the problem for above-mentioned existence, a kind of agricultural insecticidal bactericidal composition that contains pymetrozine and epoxiconazole is provided, reduce the usage amount of medicament in the situation that guarantee control efficiency, thereby reduce cost accounting.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of agricultural insecticidal bactericidal composition that contains pymetrozine and epoxiconazole, formed by active ingredient, auxiliary agent and excipient, wherein, active ingredient is comprised of pymetrozine and epoxiconazole, and the weight ratio of pymetrozine and epoxiconazole is 1:80-80:1; The weight percent content of each component is in the composition: pymetrozine 1%～80%, and epoxiconazole 1%～80%, auxiliary agent 1%～30%, excipient complements to 100%.
Described auxiliary agent is calcium dodecyl benzene sulfonate, neopelex, calcium lignosulfonate, sodium lignin sulfonate, ammonium sulfate, sodium carboxymethylcellulose, bay alcohol radical sodium sulphate, mersolates, polycarboxylate, the fatty acid modified thing of alkanol, spaonin powder, pull open powder, sodium metnylene bis-naphthalene sulfonate, fatty alcohol-polyoxyethylene ether, the diphenylethyllene phenol polyoxyethylene poly-oxygen propylene aether, epoxidized soybean oil, sorbierite, isopropyl alcohol, sodium bentonite, polyoxyethylene styryl phenyl ether, styrylphenol polyoxyethylene ether, the phenethyl phenol polyethenoxy ether, the combination of one or more in styryl phenyl polyoxy ethyl polyoxyethyl propyl ether or the alkylphenol polyoxyethylene.
Described excipient is one or more combination of kaolin, precipitated calcium carbonate, bentonite, white carbon, water, methyl alcohol, castor oil, dimethylbenzene, cyclohexanol, glycerine, ethyl acetate, ethylene glycol, polyvinyl alcohol, crosslinked starch or clay.
The described agricultural insecticidal bactericidal composition that contains pymetrozine and epoxiconazole is formulated as water dispersible granules, wetting powder, suspending agent, oil-suspending agent, microemulsion, aqueous emulsion, film-spreading oil solution or sustained-release granular formulation.
The agricultural insecticidal bactericidal composition that contains pymetrozine and epoxiconazole of the present invention, the damage by disease and insect that can prevent and treat comprises paddy rice white-backed planthopper, brown planthopper, small brown rice planthopper, rice blast, rice sheath blight disease, rice green smut, wheat sharp eyespot, wheat powdery mildew, wheat rust, wheat aphid, leaf spot of peanut, sigatoka and banana aphid.
The present invention has the following advantages:
1, pymetrozine and epoxiconazole belong to the farm chemical ingredients of the different mechanisms of action in the composition of the present invention, there is resistance risk in long-term use of single composition, the two composite use can prolong the service life of each single dose, manages as a whole for the resistance problem of medicament to have great importance.
2, composition of the present invention, empirical tests shows comparatively significant synergistic effect in certain ratio range, the control efficiency of composition has had significant raising than single dose, has also reduced drug cost when having reduced the using dosage of agricultural chemicals, and the adverse effect of environment is also significantly reduced.
3, the composition pesticide that provides of the present invention has enlarged the control spectrum, prevention and treatment range is more extensive, all has comparatively good preventive effect for insect pest diseases such as paddy rice white-backed planthopper, brown planthopper, small brown rice planthopper, rice blast, rice sheath blight disease, rice green smut, wheat sharp eyespot, wheat powdery mildew, wheat rust, wheat aphid, leaf spot of peanut, sigatoka, banana aphids.To the virus diseases such as serious black streak dwarf, stripe virus disease occured in recent years, the malicious source that passes can cut off, as cut off the malicious source that passes poison such as small brown rice planthopper, white-backed planthopper, brown planthopper, leafhopper, aphid etc., when reducing insect and cause harm, reach the effect of controlling the worm diseases prevention.
