Description
Technical field
The invention belongs to pesticide field, relate in particular to the compounded pesticides of a kind of indoxacarb and ethyl multiple killing teichomycin.
Background technology
Indoxacarb (indoxacarb) is recently a kind of insecticide of Development and Production of du pont company.Can effectively prevent and treat grain, cotton, really, the various pests on the crop such as vegetables, be applicable to prevent and treat beet armyworm, diamond-back moth, cabbage caterpillar, prodenia litura, tomato moth, cotton bollworm, oriental tobacco budworm, leaf rollers, codling moth, leafhopper, spark, colorado potato beetle on the crops such as wild cabbage, flower coconut palm class, cabbage mustard, tomato, capsicum, cucumber, little cucumber, eggplant, lettuce, apple, pears, peach, apricot, cotton, potato, grape.Indoxacarb has tags and stomach poison function, all effective to each instar larvae.Simultaneously, this composition insecticidal mechanism is unique, does not have cross resistance with other insecticides.In efficient insecticide, it also is the insecticide of low toxicity, environmental protection.
Ethyl multiple killing teichomycin (Spinetoram) is a kind of novel ethyl multiple killing teichomycin insecticides of being produced by Dow AgroSciences, it can effectively control a kind of thorny primary pest---the stupid moth of apple on important insect pest, the especially fruit tree on fruit tree and the nut.Be mainly used in preventing and treating lepidopterous larvae, thrips and Liriomyza etc., striped rice borer, beet armyworm, Liriomyza, thrips, prodenia litura, lima bean pod borer are had good control efficiency.It is higher that it has biologically active, and insecticidal spectrum is wider, and quick-acting is better, and the lasting period is longer, resistance of rainwater washing against, the characteristics such as low toxic and environment-friendly.
Rice-stem borer (Chilo suppressalis) popular name borer, borer, moth stalk worms etc. are the formidable opponents of paddy rice.Larva moth food stem stalk causes the withered heart, and striped rice borer has the strain of turning harm habit, and a Chilo spp larvae can endanger many strains paddy rice, causes dead leaf sheath, the withered heart.If a lot of withered heart seedlings often can appear in untimely control, field, the part field is not is not prevented and treated striped rice borer because of nursery period, and field withered heart seedling ratio is up to 30% now, and part location, field withered heart seedling ratio surpasses 50%, causes very large loss.
At present, the agricultural chemicals Main Means of making agricultural pests as chemical control is used very extensive.Yet, use for a long time the agricultural chemicals of single variety, impel easily insect to produce resistance, increase the weight of the consumption of agricultural chemicals.Environment is caused larger pollution.Field trial shows, the existing medicament another kind of medicament different from mechanism of action is mixed, can not only postpone resistance and produce, can also improve drug effect and residual period, thereby reduce usage amount, reduce peasant's dispenser cost, therefore we are composite in the hope of reaching the most of insect of effective control with indoxacarb and ethyl multiple killing teichomycin, and the effect of environmental contamination reduction improves drug effect and lasting period simultaneously, reduce peasant's labour cost, had good economic benefit.
Summary of the invention
The purpose of this invention is to provide that a kind of insecticidal activity is efficient, lasting effect is long, the compounded pesticides of the high and low poison of quick-acting, environmental protection.Being specifically related to indoxacarb and ethyl multiple killing teichomycin is the pesticidal preparations of basis.
In the above-mentioned compounded pesticides, contain indoxacarb 1%～50%, ethyl multiple killing teichomycin 1%～50%, indoxacarb and ethyl multiple killing teichomycin percentage by weight are at 1:50～50:1.
Utilize the described compounded pesticides of the invention described above, be equipped with the known auxiliary agent of those skilled in that art, can make formulation of the present invention with the known method of those skilled in that art.Its formulation that can process is suspending agent, aqueous emulsion, water dispersible granules.
The present invention compared with prior art can produce higher synergy, overcomes and delayed the generation of pest resistance to insecticide, has enlarged insecticidal spectrum, and desinsection speed is fast, has reduced use cost, has alleviated the pollution of toxicity to environment.
The applicant has at first carried out the research that prescription screens to indoxacarb and ethyl multiple killing teichomycin, because indoxacarb and ethyl multiple killing teichomycin are two kinds of compositions that insecticidal activity is very high, according to their effect characteristics and mechanism of action, the object of indoor biometrics is decided to be rice-stem borer, specifically tests situation and the result is as follows:
Experimental drug adopts the former medicine of 95% indoxacarb and the former medicine of 95% ethyl multiple killing teichomycin, is mixed with needed preparation by the patent application people.According to the matched proportion density of setting, it is for subsequent use to be mixed with the desired concn liquid, and employed former medicine and auxiliary agent are other producers and buy.
Adopt capillary micro intravenous drip method, capillary micro intravenous drip device volume is 1.0 μ L.With the micro intravenous drip device liquid is pursued a drop in the back side of striped rice borer, each concentration is processed about 100 striped rice borer, after the processing striped rice borer is put into a dependent insect cage, and the built-in paddy rice of cage is for taking food, in addition with 100 larvas of acetone drop in contrast.Striped rice borer after treatment still is placed in the receptacle, checks lethality behind the 48h.Data are processed with the SPSS software statistics.Obtain toxicity regression formula, the lethal concentration of 50, correlation coefficient etc., and obtain co-toxicity coefficient with the abundant method of Sun Yun.
The co-toxicity of mixture preparation adopts the abundant co-toxicity coefficient method representation of Sun Yun:
The theoretical toxicity index A=∑ of mixture preparation (toxicity index of certain medicine * percentage of this pharmaceutically active ingredient in mixture).
Wherein, C was synergistic effect greater than 120 o'clock, less than 80 o'clock be antagonism, be addition at 80～120 o'clock.

Example five, 51% indoxacarb ethyl multiple killing teichomycin water dispersible granules
Active ingredient, wetting agent, dispersant, adhesive, filler etc. are fully mixed in the ratio of prescription, behind ultra-fine pulverizer disintegrating, add an amount of purified water, make water dispersible granules through kneading, granulation, drying, screening.
Example six, 18% indoxacarb ethyl multiple killing teichomycin water dispersible granules
Active ingredient, wetting agent, dispersant, adhesive, filler etc. are fully mixed in the ratio of prescription, behind ultra-fine pulverizer disintegrating, add an amount of purified water, make water dispersible granules through kneading, granulation, drying, screening.
Example seven, 22% indoxacarb ethyl multiple killing teichomycin suspending agent
According to the prescription requirement, take water as medium, will grind in the adding sand mills such as active ingredient, wetting agent, dispersant, thickener, defoamer, add emulsification in the high-shear emulsifying still, make suspending agent.
According to above-mentioned six examples, carry out the field efficacy experiment of indoxacarb and ethyl multiple killing teichomycin complex preparation control striped rice borer, determine the effect of prescription control striped rice borer; Simultaneously by with the Contrast on effect of indoxacarb, ethyl multiple killing teichomycin single dose, verify the synergistic effect after composite.Concrete test method and data are as follows:
51% indoxacarb ethyl multiple killing teichomycin WDG and other example formulations are carried out the test of field control striped rice borer, compare with 10% indoxacarb suspending agent and 10% ethyl multiple killing teichomycin suspending agent simultaneously, test site is Yingcheng City Tian Dian town, Xiaogan Prefecture, Hubei Province, time is on June 30th, 2011, test totally four processing, each processes three repetitions, residential quarter randomized arrangement, residential quarter area 100m
2, the planting habit of all residential quarters all planting habit with local is identical, and the record dispenser same day and the synoptic data in a week thereafter are specific as follows:
Table 2 duration of test meteorological data
The investigation standard is: 7d gets killed strain 50 strains at random behind the medicine in each residential quarter, and the life or death number of bat dish method metering nymph calculates lethality; 15d, 25d adopt every residential quarter 150 clumps of parallel sampling method samplings behind the medicine, investigate withered calculation, calculate at last withered heart rate and seedling protecting effect.Concrete data (data are the mean value of three repetitions) are as follows:
Table 3 51% indoxacarb ethyl multiple killing teichomycin WDG and other compounded formulas are to the striped rice borer field control effectiveness test
Annotate: data are the mean value that repeats for 3 times in the table, and letter is all Duncan testing differentia remarkable time mutually: in June, 2011 place: the Hubei Xiaogan
As can be seen from the above data, different formulations carries out in the composite process, using under the identical effective dose, after indoxacarb and ethyl multiple killing teichomycin are composite, the preventive effect of preparation will be apparently higher than two kinds of single doses, wherein the control rate of 10% indoxacarb ethyl multiple killing teichomycin EW 25d behind medicine is 92.06%, control rate is the highest in six kinds of examples, 18% indoxacarb ethyl multiple killing teichomycin SC and 33% indoxacarb ethyl multiple killing teichomycin WDG efficient of preventing and treating of 25d behind medicine also reach 91.20% and 90.85%, compare significant difference with other example.Compare 25d preventive effect behind 10% indoxacarb suspending agent and the 10% ethyl multiple killing teichomycin suspending agent medicine, very strong synergistic effect is arranged, prove that two kinds of active ingredients are composite, insecticidal enhancing effect is obvious.
