Abstract
The invention relates to an insecticidal composition of butene-fipronil and spinosad, which comprises the following components: 0.5%-20% of butene-fipronil and 4%-35% of spinosad. The invention has the advantages that the insecticidal composition has good control effect on lepidopteran, homoptera and thysanoptera pets and good practicability; and the insecticidal composition can reduce dosages, delay generation of drug resistance and decrease pollution of the environment.
Description
Technical field the invention belongs to pesticide field, relates in particular to the Pesticidal combination of a kind of butene-fipronil and multiple killing teichomycin.
Background technology butene-fipronil (fipronil) belongs to a kind of Phenylpyrazole insecticides, insecticidal spectrum is wide, to insect take stomach poison function as main, have concurrently and tag and certain systemic action, its mechanism of action is to hinder the chloride metabolism of insect γ～aminobutyric acid control, therefore the important pests such as aphid, leafhopper, plant hopper, lepidopterous larvae, fly class and coleoptera are had very high insecticidal activity, to crop without poisoning.During foliage spray, water rice hopper, rice-stem borer, Yellow Rice Borer, rice leaf roller, diamond-back moth, imported cabbageworm, rice thrips etc. are all had high-level preventive effect, and the lasting period is long.
It is a kind of macrolides Nuisanceless high-efficient biological insecticides that extract in the sugared many born of the same parents fermented liquid of thorn that multiple killing teichomycin has another name called pleocidin (Spinosad).Produce parent strain soil actinomycetes thorniness saccharopolyspora strain (the Saccharopolyspora spinosa Metrz ﹠amp of multiple killing teichomycin; Yao) initial separation 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.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 affect 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.Without systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some takes food the pest species of blade in a large number in coleoptera and the orthoptera, relatively poor to the control efficiency of sucking pest and mite class.Safer to predatory natural enemy insect, unique because of insecticidal action mechanism, not yet find at present to have mutual drug-fast report with other insecticides.Safe without poisoning to plant.Be suitable for using on vegetables, fruit tree, gardening, the crops.Can make insect benumb rapidly, paralyse, cause at last death.Its desinsection speed can compare favourably with chemical pesticide.Safe, and with present common insecticide be the biological insecticides of low toxicity, efficient, low-residual without cross resistance, existing efficient insecticidal properties has again the characteristic of beneficial insect and mammalian safe is arranged, the most suitable pollution-free vegetable, Production of fruit are used.
Because agricultural pests causes very large loss to crops production every year, consider the agricultural chemicals of long-term use single variety, easily impel insect to produce resistance, environment is caused larger pollution, field trial shows, the existing medicament another kind of mixed pesticide different from mechanism of action, can not only postpone resistance and produce, can also improve drug effect and residual period, reduce usage amount, Cost reduction, so we use butene-fipronil and the composite expansion insecticidal spectrum of multiple killing teichomycin.Not only most of insect, environmental contamination reduction be can effectively prevent and treat, drug effect and lasting period also improved.The synergistic complex of agricultural chemicals is the effective ways that enlarge the pesticide control spectrum and improve drug effect.
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.Be specifically related to the pesticide water dispersible granules that butene-fipronil and multiple killing teichomycin are basis.
Water dispersible granules is compared with missible oil, can not only save a large amount of organic solvents, significantly reduces the pollution to environment when stopping the organic solvent use, and drug effect also is improved to some extent; Compare with wettable powder, suspending agent, active constituent content is high, and volume is little, has increased safety, gives packing, stores, transports and brought very large economic benefit and social benefit.Thus, still there are a lot of deficiencies in the complex preparations such as missible oil, suspending agent, wetting powder at aspects such as economy, serviceability, environmental protection, packed and transported, in the urgent need to a kind of product forms of safer, efficient, environmental protection is provided.
Utilize the described insecticides 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 water dispersible granules (WDG).
The advantage that the present invention has and beneficial effect: 1. the desinsection scope is wide, to the Lepidoptera super-high-efficient; 2. 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.

Analyze above-mentioned data, measurement result shows, when butene-fipronil and multiple killing teichomycin different proportion were composite, the co-toxicity coefficient of prescription all had obvious synergistic effect all greater than 120.Wherein fill a prescription 5 and prescription 3 co-toxicity coefficients maximum, be respectively 167.38 and 175.16.
By the indoor biometrics test, select the field trial that the larger prescription of CTC 3, prescription 5 and the less prescription 1 of CTC are prevented and treated rice-stem borer, determine the effect of prescription control rice-stem borer; Simultaneously by with the Contrast on effect of butene-fipronil, multiple killing teichomycin single dose, verify the synergistic effect after composite.Concrete test method and data are as follows:
Test the test of pesticide effectiveness that one: 2% butene-fipronil, 5% multiple killing teichomycin WDG, 5% butene-fipronil WDG, 50% multiple killing teichomycin WDG do the field control striped rice borer.Test site be Hanchuan City Liu of Xiaogan Prefecture, Hubei Province every the town, the time is on June 14th, 2009, the test totally four processing, each processes three repetitions, residential quarter randomized arrangement, residential quarter area 67m
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 9 duration of test meteorological data
| Date | 6～14 | 6～15 | 6～16 | 6～17 | 6～18 | 6～19 | 6～20 |
| Temperature ℃ | 26～33 | 23～32 | 25～34 is cloudy | 25～33 | 24～31 | 23～31 | 24～32 |
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 Chilo spp larvae is looked in stripping, 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:
The effect table of table 10 3% butene-fipronil, 33% multiple killing teichomycin WDG 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, 2009 place: the Hubei Xiaogan
As can be seen from the above data, in the situation that identical using dosage, 3% butene-fipronil, 33% multiple killing teichomycin 25d control rate behind medicine can reach 96.1%, the effect when preventive effect is higher than 3% butene-fipronil and the use of 33% multiple killing teichomycin single dose far away, and difference is extremely remarkable.
Test two: test method, investigation method and meteorological data are the same, and concrete test data is as follows:
The effect table of table 11 3% butene-fipronil, 30% multiple killing teichomycin 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, 2006 place: the Jianli, Hubei
As can be seen from the above data, in the situation that identical using dosage, 3% butene-fipronil, 30% multiple killing teichomycin 25d control rate behind medicine can reach 95.7%, the effect when preventive effect is higher than 3% butene-fipronil WDG and the use of 30% multiple killing teichomycin WDG single dose far away, and difference is extremely remarkable.
Test three: test method, investigation method and meteorological data are the same, and concrete test data is as follows:
The effect table of table 12 2% butene-fipronil, 5% multiple killing teichomycin 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, 2009 place: the Hubei Xiaogan
As can be seen from the above data, in the situation that identical using dosage, 2% butene-fipronil, 5% multiple killing teichomycin 25d control rate behind medicine can reach 86.1%, the effect when preventive effect is higher than 2% butene-fipronil WDG and the use of 5% multiple killing teichomycin WDG single dose far away, and difference is extremely remarkable.
By above-mentioned three field control effectiveness tests, the effect that can find out prescription 3, prescription 5 control rice-stem borers is best, this also matches with the result of indoor biometrics, and (CTC is larger, synergistic effect is larger), but the two difference is not remarkable, as considering the factor of pesticide cost, prescription 3 is best, the most economical proportionings of effect again; Also verified simultaneously when butene-fipronil and multiple killing teichomycin are composite by different proportion, the control efficiency of rice-stem borer all has been better than the effect of butene-fipronil and the use of multiple killing teichomycin single dose, certain synergistic effect has been arranged.
By above-mentioned three field control effectiveness tests, can determine to fill a prescription 3 for preventing and treating the more suitable prescription of rice-stem borer, 3% butene-fipronil, 30% multiple killing teichomycin WDG (prescription 3) has been carried out further test, filter out the optium concentration of control striped rice borer.Experimental scheme 4g/ mu, 5g/ mu, 6g/ mu and 4 concentration gradients of 7g/ mu are also done contrast with the effect of 5% butene-fipronil (5g/ mu), 50% multiple killing teichomycin (5g/ mu), test method and investigation method are the same, and concrete data (mean values of three repetitions) are as follows:
Table 13 prescription 3 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, 2009 place: the Hubei Xiaogan
Can find out 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, 3% ethiprole, 30% multiple killing teichomycin WDG consumption is 5g/ mu, the seedling protecting effect of 25d is 96.4% behind the medicine, and apparently higher than 5% ethiprole and 50% multiple killing teichomycin, difference is extremely remarkable; When the mu consumption was 6g and 7g, 25 days seedling protecting effect and 5g/ mu was roughly the same after medication, and difference is not remarkable.Therefore, under the prerequisite of considering the mu cost, should advocate mu usage amount is 5g/ mu.
