The pesticide composition provided by the invention can effectively control various aphids, leafhoppers, planthoppers, whiteflies, scarab larvae, potato beetles, nematodes, ground beetles, Phyllocnistidae and other pests, also has good activity to powdery mildew, rust disease, glume blight, net blotch, downy mildew, rice blast and the like, can be used for stem and leaf mist spray and seed treatment, and also can be used for soil treatment.
Description
Technical field
The present invention relates to a kind of crops pest, seed treatment that growth is adjusted in controlling disease, strong sprout, promotion, be specifically related to a kind of by Diacloden and azoxystrobin compound for the treatment of the suspension seed-coating agent of seed, belong to biochemical pesticide field.
Background technology
Diacloden belongs to anabasine insecticide, and its mechanism of action is similar to Imidacloprid, alternative suppression insect CNS nicotinic acetylcholine esterase acceptor, and then blocks the normal conduction of insect CNS, causes insect to occur the instant death of paralysis.Not only have tag, stomach toxicity, systemic activity, and there is higher activity, better safety, wider insecticidal spectrum and the feature such as speed of action is fast, the lasting period is long, be replace that those are high to mammalian toxicity, there have to be residual and the organic phosphor of environmental problem, carbamate, organochlorine insecticides better kind.To coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, effectively can prevent and treat the various pests such as various aphid, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner.Both can be used for cauline leaf process, seed treatment, also can be used for soil treatment.Object is used to be rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus etc.Use to crop safety, without poisoning under recommended dose.
Fluoxastrobin is a kind of interior absorption and curative fungicide agent of efficient, wide spectrum, has protection, treats and roots out triple function.Unique by the beta-methoxy acrylic ester bactericide of xylem to top conductive.By being combined the synthesis to stop energy in fungi with cytochrome b, there is effect to all stages of fungal disease.Fluoxastrobin fungicidal spectrum is very wide, and as anthracnose, powdery mildew, rust, leaf spot, downy mildew, epidemic disease, southern blight and by the microbial damping off of miliary damping-off, the microbial reaping hook fusarium wilt of reaping hook etc. all has well treatment and prevention effect.Can be used for cauline leaf spraying, seed treatment, also can carry out soil treatment, be mainly used in cereal, paddy rice, peanut, grape, potato, fruit tree, vegetables, coffee, lawn etc.
Both at home and abroad extensive research is carried out, the development and application report of the kinds such as existing single dose suspending agent (SC), wetting powder (WP), water dispersible granules (WDG) to the application technology of Diacloden and Fluoxastrobin and formulation technology.
Summary of the invention
The object of this invention is to provide a kind of high-efficiency low-toxicity, the active ingredient being conducive to integrated control crop pest and disease is the composition pesticide of Diacloden and Fluoxastrobin.
Another object of the present invention is to provide and this composition pesticide is used for seed pelleting, prevent and treat underground pests, disease simultaneously, improve emergence rate.
Technical solution of the present invention: for achieving the above object, the invention provides the composition pesticide that a kind of effective ingredient is made up of Diacloden and Fluoxastrobin, the ratio of weight and number of Diacloden and Fluoxastrobin is 1 ~ 85: 1 ~ 85, Diacloden and the percentage by weight of Fluoxastrobin weight summation in composition pesticide are 5 ~ 78%, preferred weight percent is 20 ~ 58%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Composition pesticide of the present invention can according to well known to a person skilled in the art method, be mixed with and dispersible oil suspending agent, suspending agent, aqueous emulsion, microemulsion, suspension seed-coating agent, microcapsule formulations, wetting powder, wet seed dressing, the formulation of the applicable agricultural uses such as water-dispersible granules, missible oil, soluble liquid, tablet.
Described composition pesticide, also containing usual auxiliaries, comprises wetting agent, dispersant, solvent, emulsifier, thickener, defoamer, antifreezing agent, disintegrant, binding agent, film forming agent, stabilizing agent, filler, one or more the mixing such as deionized water.Can change to some extent according to different situations, be not particularly limited.
Product of the present invention can the form of finished product preparation provide, and insecticide-applying way can be sprayed, pesticide-clay mixture, seed dressing, to spread fertilizer over the fields etc. multiple.
The present composition, can be used for insect and the disease of preventing and treating the crops such as rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus.
Compared with prior art, the invention has the advantages that: 1) composite have obvious synergistic effect, improves control efficiency; 2) pesticide resistance of damage by disease and insect is delayed; 3) two kinds of active ingredients are composite, reduce cost and the pollution to environment.
Specific embodiments
In order to make object of the present invention, technical scheme and advantage clearly understand, the following specific embodiment of the present invention is described further technical scheme of the present invention, but the invention is not restricted to following specific embodiment.
Embodiment 1: Diacloden and azoxystrobin compound are to the synergy determination test method of cucumber root-knot nematode: get the cucumber root producing a large amount of root knot, running water is rinsed well gently, with the milky egg capsule on dissecting needle gently picking old complaint, put into the little culture dish of diameter 6 centimetres, add a small amount of sterile water, hatch 3 ~ 4 days in 25 DEG C of insulating boxs, collect 2 instar larvaes, and adding sterile water, to be mixed with the suspension of finite concentration (500/about ml) for subsequent use.Setting 5 concentration gradient process, take sterile water as blank.Get 96 porocyte culture plates, every hole adds the medicament 150 μ l of the variable concentrations prepared, add isopyknic nematode suspension again, heat insulating culture under 25 DEG C of conditions, different time after treatment checks the amount of survival of southern nematode 2 instar and dead quantity respectively, nematode is stiff motionless for dead worm, and nematode is the worm that lives in bending wriggling state, calculates lethality and corrected mortality.
According to survey data, calculate the corrected mortality of each process.And adopt the abundant method of Sun Yun to calculate the co-toxicity coefficient (CTC value) of mixture with reference to NY/T1154,1-2006.If contrast lethality < 5%, does not correct; Contrast lethality, between 5% ~ 20%, corrects; Contrast lethality > 20%, test need be reformed.Be independent variable X with the logarithm value of drug concentration (mg/L), with the probit value of corrected mortality for dependent variable Y, set up virulence regression equation formula respectively, adopt DPS software to calculate the LC of single dose and each proportioning mixture
50, LC
90, 95% confidence limit and mixture co-toxicity coefficient thereof, compare synergy situation.According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC value) >=120 shows as synergistic effect; Co-toxicity coefficient (CTC value)≤80 shows as antagonism; 80 < co-toxicity coefficients (CTC value) < 120 shows as summation action.
