Abstract
The invention relates to an insecticidal composition consisting of spinosad and fenobucarb. The insecticidal composition comprises 0.5 to 10 percent of spinosad and 1 to 35 percent of fenobucarb. The insecticidal composition has good prevention and control effects on plutella xylostella, reduces using amount, delays medicament resistance, reduces pollution to the environment and does not cause chemical injury easily.
Description
Technical field
The invention belongs to pesticide field, relate in particular to the Pesticidal combination of a kind of pleocidin and Bassa.
Background technology
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 pleocidin has another name called multiple killing teichomycin (Spinosad).Produce parent strain soil actinomycetes thorniness saccharopolyspora strain (the Saccharopolyspora spinosa Metrz ﹠amp of pleocidin; Yao) initial separation is from one of the Caribbean discarded wine brewing field.The mode of action novelty of pleocidin can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Pleocidin 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 resistance and the living possibility of 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.Pleocidin 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 food 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.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.Pleocidin, its structural formula is as follows:
Bassa (Fewobucarb), carbamate insecticide is mainly blocked normal nerve conduction by acetylcholine esterase inhibition, causes the imbalance of whole physiological and biochemical procedure, and insect is poisoned to death.Plant hopper, spider mite kind are had special efficacy, and desinsection is rapid, but residual effect is short, can only keep 4-5 days.Carbamates combines with cholinesterase so that compound molecule is whole, and inhibitory action reduces after the hydrolysis, so virulence is lower, metabolism faster is an innocuous substance in animal and plant body and soil.Simultaneously such material has also that quick-acting is good, the lasting period short, selectivity is strong and with other kind pesticide compositionals the characteristics of notable synergistic effect is arranged.
Bassa (Fewobucarb) chemical name 2-isopropyl phenyl-N-methyl carbamate, its chemical constitution is as follows:
Because agricultural pests causes very big loss to crops production every year, consider the agricultural chemicals of long-term use single variety, impel insect to produce resistance easily, environment is caused bigger pollution, field trial shows, the existing medicament another kind of mixed pesticide different with mechanism of action, can not only postpone resistance and produce, can also improve drug effect and residual period, reduce usage amount, reduce cost, so we enlarge insecticidal spectrum with pleocidin and fenobucarb composite.Not only can effectively prevent and treat most of insect, reduce environmental pollution, also improve drug effect and lasting period.
Summary of the invention

Analyze above-mentioned data, measurement result shows that when pleocidin and Bassa different proportion were composite, the co-toxicity coefficient of prescription all had obvious synergistic effect all greater than 120.Wherein fill a prescription four and the prescription five co-toxicity coefficient maximums, be 337.62 and 212.28.
By the indoor biometrics test, select the field trial that the bigger prescription of CTC four, prescription five and the less prescription one of CTC are prevented and treated diamond-back moth, determine the effect of prescription control diamond-back moth; Simultaneously by with the contrast of the effect of pleocidin, the agent of Bassa list, verify the synergistic effect after composite.Concrete test method, data are as follows:
Test one:10% Bassa, 7.5% pleocidin WDG, 15% Bassa WP, 2.5% pleocidin WDG do the test of pesticide effectiveness of field control diamond-back moth.Test site is Chen He town, Yingcheng City county, Xiaogan Prefecture, Hubei Province, and the time is on July 29th, 2010, test totally four processing, and each handles three repetitions, sub-district randomized arrangement, sub-district area 67m
2, the planting habit of all sub-districts 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
The investigation standard is: concrete data (data are the mean value of three repetitions) are as follows:
The effect table of table 10 10% Bassa, 7.5% pleocidin WDG and other chemical control diamond-back moths
From above data as can be seen, under the situation of identical using dosage, 10% Bassa, 7.5% pleocidin 7d control rate behind medicine can reach 90.0%, the effect when preventive effect is higher than 10% Bassa and 7.5% pleocidin list agent use 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 15% Bassa, 5% pleocidin WDG and other chemical control diamond-back moths
From above-mentioned data as can be seen, under the situation of identical using dosage, 15% Bassa, 5% pleocidin 7d control rate behind medicine can reach 89.4%, the effect when preventive effect is higher than 15% Bassa and 5% pleocidin list agent use 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 25% Bassa, 1% pleocidin and other chemical control diamond-back moths
From above data as can be seen, under the situation of identical using dosage, 25% Bassa, 1% pleocidin 7d control rate behind medicine can reach 83.3%, the effect when preventive effect is higher than 25% Bassa and 1% pleocidin list agent use far away, and difference is extremely remarkable.
By above-mentioned three field control effectiveness tests, fill a prescription four as can be seen, the effect of prescription five control diamond-back moths is best, this also matches with the result of indoor biometrics, and (CTC is big more, synergistic effect is big more), but the two difference is not remarkable, as considering the factor of pesticide cost again, prescription four is best, the most economical proportionings of effect; Also verified simultaneously Bassa and pleocidin by different proportion when composite, the control efficiency of diamond-back moth all has been better than the effect of Bassa and pleocidin list agent use, certain synergistic effect has been arranged.
By above-mentioned three field control effectiveness tests, can determine to fill a prescription four for the more suitable prescription of control diamond-back moth, 10% Bassa, 7.5% pleocidin WDG(is filled a prescription four) and carried out further test, filter out the optium concentration of control diamond-back moth.Experimental scheme 10g/ mu, 12.5g/ mu, 15g/ mu and 4 concentration tonsures of 17.5g/ mu are also done contrast with the effect of 15% Bassa (20g/ mu), 2.5% pleocidin (60g/ mu), test method and investigation method are the same, and concrete data (mean values of three repetitions) are as follows:
Table 13 prescription four different amounts control diamond-back moth effect table
From the result of the above-mentioned test of pesticide effectiveness as can be seen, along with the increase of prescription dosage, drug effect also increases to some extent, 10% Bassa, 7.5% pleocidin WDG consumption is a 15g/ mu, the preventive effect of 7d is 89.9% behind the medicine, and apparently higher than 10% Bassa 20g/ mu and 7.5% pleocidin 15g/ mu, difference is extremely remarkable; When the mu consumption was 17.5g, 7 days preventive effect and 15g/ 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 15g/ mu.
