Description
Technical field
The invention belongs to pesticide field, relate in particular to the Pesticidal combination of a kind of cyanogen insect amide and multiple killing teichomycin.
Background technology
Cyanogen insect amide also is bromine cyanogen insect amide (cyantraniliprole); It is E.I.Du Pont Company's second generation ryania acceptor inhibitor insecticides that success is developed after the chlorine insect amide; Cyanogen insect amide is to form through the various polar groups that change on the phenyl ring; Have more efficiently, applicable crops is more extensive, can effectively prevent and treat Lepidoptera, Semiptera and coleopteran pest.Cyanogen insect amide has stronger permeability, and medicament can pass stem's epidermal cell and get into xylem, conducts to other positions along xylem.Cyanogen insect amide can be used for the pest control of crops such as leguminous plant, cotton, paddy rice, beet, soybean, brassicaceous vegetable, muskmelon.
It is a kind of macrolides Nuisanceless high-efficient biological insecticides that in thorn sugared many born of the same parents bacterium (Saccharopolyspora spinosa) zymotic fluid, extract that multiple killing teichomycin has another name called pleocidin (Spinosad).Parent strain soil actinomycetes thorniness saccharopolyspora strain (the Saccharopolyspora spinosa Metrz & Yao) initial separation that produces multiple killing teichomycin is from one of the Caribbean discarded wine brewing field.The mode of action of multiple killing teichomycin is novel, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Multiple killing teichomycin also can influence the GABA acceptor, but mechanism of action is unclear.Whether also do not know at present has cross tolerance with the insecticide of other types.These compounds can cause that target plant-feed insect such as caterpillar, leaf miner, thrips and leaf-feeding beetle are dead rapidly; Although administrative department's strong request is not used when resistance occurs, the moderate residual activity of this compound has reduced the resistance possibility living with mass-sending.The acting body of nicotinic acid acetylcholinergic receptor can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Multiple killing teichomycin also can influence the GABA acceptor, insect is had tag fast and stomach poison function, and blade is had stronger osmosis, can kill subepidermal insect, and the longevity of residure is longer, and some insects are had certain ovicidal action.No systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some measures the pest species of eating blade greatly in coleoptera and the orthoptera, relatively poor to the control efficiency of sucking pest and mite class.Safer to the predator insect, unique because of insecticidal action mechanism, do not find as yet at present to have mutual drug-fast report with other insecticides.Plant safety there is not poisoning.Be suitable for using on vegetables, fruit tree, gardening, the crops.Insecticidal effect receive to rain influence less.Can make insect benumb rapidly, paralyse, cause death at last.Its desinsection speed can compare favourably with chemical pesticide.Safe, and do not have the biological insecticides that cross resistance is low toxicity, efficient, low-residual with present common insecticide, existing insecticidal properties efficiently has again the characteristic of beneficial insect and mammalian safe being arranged, the most suitable pollution-free vegetable, fruit production application.
Since problems such as independent at present cyanogen insect amide or the multiple killing teichomycin of using exists drug cost bigger, and quick-acting or lasting effect are relatively poor, and use single agent to be easy to generate pesticide resistance, and long-term use meeting causes bigger pollution to environment.In order to develop quick-acting and lasting effect is higher, lower-cost agricultural chemicals, we have carried out indoor biometrics and field efficacy experiment, filter out the composite prescription of cyanogen insect amide and multiple killing teichomycin, and it has the synergistic effect of obvious point.
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 Pesticidal combination of the high and low poison of quick-acting, environmental protection.Concrete relate to cyanogen insect amide and multiple killing teichomycin is the pesticidal preparations of basis.
Above-mentioned Pesticidal combination contains cyanogen insect amide 1%～40%, multiple killing teichomycin 1%～30%.
Utilize the described insecticides of the invention described above, be equipped with the known auxiliary agent of those skilled in that art, can process formulation of the present invention with those skilled in that art's known method.Its formulation that can process is suspending agent, water dispersible granules.
Advantage that the present invention has and beneficial effect: 1. the desinsection scope is wide; 2. quick-acting is strong, the lasting period is long; 3. low toxicity, noresidue, nuisanceless, environmentally safe; 4. use compound formulation, two kinds of insecticides also have synergistic effect, and the consumption of two kinds of insecticides reduces during all than single use, thereby has improved insecticidal effect, has increased safety, has reduced environmental pollution.
Embodiment
Following instantiation is in order to further explain the present invention, but the present invention absolutely not only is limited to following these embodiment.Percentage all is weight percentage in the prescription, and employed former medicine and auxiliary agent are other producers and buy.
Formulation examples is following:

The water-dispersible grain agent prescription
According to the compound method of above-mentioned suspending agent and water dispersible granules, prepare multiple multiple killing teichomycin and two kinds of composite preparations of active ingredient of cyanogen insect amide of containing, carry out the indoor biometrics experiment.
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 commentaries on classics harm habit, and a Chilo spp larvae can endanger many strains paddy rice, causes dead leaf sheath, the withered heart.If untimely control, the field a lot of withered heart seedlings occur through regular meeting, and part field piece 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 big loss.Multiple killing teichomycin, cyanogen insect amide are two kinds of compositions that insecticidal activity is very high, according to their the effect characteristics and mechanism of action, the object of indoor biometrics are decided to be rice-stem borer.
The method of indoor biometrics is: adopt capillary trace drop method, capillary trace dropper volume is 1.0 μ L.With micro-dropper with soup by a drop in the back side of Chilo spp larvae, each concentration is handled about 30 larva, the culture dish that it is 9cm that per 5 larvas are put into a diameter, the built-in a small amount of feed of ware supplies to get food, in addition with 30 larvas of acetone drop as contrast.Larva after treatment still is placed in the receptacle, checks lethality behind the 48h.Data are handled 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).
C was synergistic effect greater than 120 o'clock, less than 80 o'clock be antagonism, be addition during 80-120.
Enumerate the experimental result of representational five prescriptions, active ingredient and formulation are following in five cited prescriptions at present:
Prescription one: (6% suspending agent)
Prescription two: (12% suspending agent)
Prescription three: (16% suspending agent)
Prescription four: (20% water dispersible granules)
Prescription five: (35% water dispersible granules)
The indoor biometrics experimental result that above-mentioned five cited prescriptions are carried out is listed in the table below:
The different proportionings of table 1 are to the toxicity test result of striped rice borer
Show that through above-mentioned data determination result when cyanogen insect amide and multiple killing teichomycin different proportion were composite, the co-toxicity coefficient of prescription all had obvious synergistic effect all greater than 120.It is one maximum with prescription two co-toxicity coefficients wherein to fill a prescription, and is respectively 159.01 and 168.98.
Through the indoor biometrics test, select the field trial that the bigger prescription of CTC one, prescription two and the less prescription five of CTC are prevented and treated rice-stem borer, confirm the effect of each prescription control rice-stem borer; Simultaneously through with the effect comparison of cyanogen insect amide, the agent of multiple killing teichomycin list, verify the synergistic effect after composite.Concrete test method and data are following:
Test the test of pesticide effectiveness that one: 6% cyanogen insect amide multiple killing teichomycin SC, 12% cyanogen insect amide multiple killing teichomycin SC, 35% cyanogen insect amide multiple killing teichomycin WDG do the field control striped rice borer, use 10% multiple killing teichomycin SC, 10% cyanogen insect amide SC simultaneously as contrast.The test place is the separated town of Hanchuan City Liu of Xiaogan Prefecture, Hubei Province, and the time is on June 19th, 2010, test totally four processing, and each handles three repetitions, sub-district randomized arrangement, sub-district area 80m
2, the planting habit of all sub-districts all planting habit with local is identical, and is record dispenser same day and all synoptic data thereafter, 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 sub-district, and the life or death number of Chilo spp larvae is looked in stripping, calculates lethality; 150 clumps of parallel sampling method samplings are adopted in 15d, the every sub-district of 25d behind the medicine, investigate withered calculation, calculate withered heart rate and seedling protecting effect at last.Specifically data (data are the mean value of three repetitions) are as follows:
The effect table of table 36% cyanogen insect amide pleocidin SC and other chemical control striped rice borer
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, 2010 place: the Hubei Xiaogan
Can find out from above data; Under the situation of identical using dosage; 25d behind medicine; The control rate of 6% cyanogen insect amide multiple killing teichomycin SC, 12% cyanogen insect amide multiple killing teichomycin SC reaches 84.74% and 86.35% respectively, the effect when being higher than 10% cyanogen insect amide SC and 10% multiple killing teichomycin SC list agent use far away, and difference is extremely remarkable.Simultaneously, 35% cyanogen insect amide multiple killing teichomycin 25d after medication, its control efficiency to striped rice borer has also reached 74.75%, and the preventive effect when only using a kind of single agent is significantly improved.Simultaneously, above-mentioned field trial also match (CTC is big more, and synergistic effect is big more) with the indoor biometrics test for data.
Simultaneously, be all to find out from CTC or seedling protecting effect, the control efficiency of prescription two is superior to filling a prescription one, and comprehensive dispenser cost factor is considered, thinks that prescription two is even more ideal.
12% cyanogen insect amide multiple killing teichomycin SC (prescription two) is carried out further test, filtered out the optium concentration of control striped rice borer.Experimental scheme 8g/ mu, 10g/ mu, 12g/ mu and 4 concentration gradients of 14g/ mu are also done contrast with the effect of 12% cyanogen insect amide SC (10g/ mu), 12% multiple killing teichomycin SC (10g/ mu); Test method and investigation method are the same, and specifically data (mean values of three repetitions) are as follows:
Table 4 prescription two different amounts control striped rice borer effect table
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, 2010 place: the Hubei Xiaogan
Can find out that from the result of the above-mentioned test of pesticide effectiveness along with the increase of prescription dosage, drug effect also increases to some extent; 12% cyanogen insect amide multiple killing teichomycin SC consumption is a 10g/ mu; The seedling protecting effect of 25d is 84.33% behind the medicine, and apparently higher than 12% cyanogen insect amide SC and 12% multiple killing teichomycin SC, difference is extremely remarkable; The mu consumption is when being 12g/ mu and 14g/ mu, and 25 days seedling protecting effect is 85.74 and 86.62 after medication, roughly the same with 10g/ mu, and difference is not remarkable.Therefore, under the prerequisite of considering the mu cost, should advocate mu usage amount is 10g/ mu.
