Description
Technical field
The invention belongs to pesticide field, relate in particular to a kind of Pesticidal combination that contains multiple killing teichomycin.
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 multiple killing teichomycin has another name called pleocidin (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 multiple killing teichomycin 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.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 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.
The desinsection list is a kind of analog of nereistoxin of synthetic, enters and is converted into clam worm element or dihydro nereistoxin in the insect bodies rapidly.This medicine is the acetylcholine competitive inhibitor, have stronger tag, stomach toxicity and interior suction conduction, the larva of lepidoptera pest is had the better prevention effect, this medicine is mainly used in the insect on the crops such as control sugarcane, paddy rice.
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 are with desinsection list and the composite expansion insecticidal spectrum of multiple killing teichomycin.Not only can effectively prevent and treat most of insect, reduce environmental pollution, also improve drug effect and lasting period.

Analyze above-mentioned data, measurement result shows that when desinsection list 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 the prescription 3 co-toxicity coefficient maximums, be respectively 167.38 and 175.16.
By the indoor biometrics test, select the field trial that the bigger 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 of the effect of desinsection list, the agent of multiple killing teichomycin list, verify the synergistic effect after composite.Concrete test method and data are as follows:
Test the test of pesticide effectiveness that one: 35% desinsection list, 0.5% multiple killing teichomycin WDG, 33% desinsection list WDG, 3% 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 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: 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; 15d, 25d adopt every sub-district 150 clumps of parallel sampling method samplings behind the medicine, investigate withered calculation, calculate withered heart rate and seedling protecting effect at last.Concrete data (data are the mean value of three repetitions) are as follows:
The effect table of table 1035% desinsection list 0.5% 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
From above data as can be seen, under the situation of using same dose, 35% desinsection list, 0.5% multiple killing teichomycin 25d control rate behind medicine can reach 96.1%, the effect when preventive effect is higher than 33% desinsection list and 3% multiple killing teichomycin 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 1130% desinsection list 3% 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
From above data as can be seen, under the situation of identical using dosage, 30% desinsection list, 3% multiple killing teichomycin 25d control rate behind medicine can reach 95.7%, the effect when preventive effect is higher than 77.5% desinsection list WDG and 2.5% multiple killing teichomycin WDG 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 125% desinsection list 2% 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
From above data as can be seen, under the situation of identical using dosage, 5% desinsection list, 2% multiple killing teichomycin 25d control rate behind medicine can reach 86.1%, the effect when preventive effect is higher than 5% desinsection list WDG and 2.5% multiple killing teichomycin WDG list agent use far away, and difference is extremely remarkable.
By above-mentioned three field control effectiveness tests, fill a prescription 3 as can be seen, the effect of prescription 5 control rice-stem borers 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 3 is best, the most economical proportionings of effect; Also verified simultaneously desinsection list and multiple killing teichomycin by different proportion when composite, the control efficiency of rice-stem borer all has been better than the effect of desinsection list and multiple killing teichomycin list agent use, 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, 30% desinsection list, 3% 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 tonsures of 7g/ mu are also done contrast with the effect of 50% desinsection list (5g/ mu), 5% multiple killing teichomycin (5g/ mu), and 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
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, 30% desinsection list, 3% multiple killing teichomycin WDG consumption is a 5g/ mu, the seedling protecting effect of 25d is 96.4% behind the medicine, and apparently higher than 50% desinsection list and 5% 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.
