Description
Technical field
The invention belongs to pesticide field, relate in particular to the Pesticidal combination of a kind of second worm nitrile and 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.
Second worm nitrile is the novel pyrazole insecticides, and insecticidal spectrum is wide.Disturb chloride channel by γ-An Jidingsuan (GABA), insect is caused death thereby destroy central nervous system (CNS) normal activity.This medicine is tightr to the white clothing constraint comparison vertebrate of insect GABA chloride channel.Thereby provide very high selection toxicity.Its mechanism of action is different from main insecticide families such as pyrethroid, organic phosphor, carbamate, does not almost produce the chance of interactivity with the existing insecticide of majority.Therefore, it is the desirable reserve kind of resistance management, can be with the mixed pesticide of other chemical family, be used alternatingly.
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, and field trial shows, the existing medicament another kind of mixed pesticide different with mechanism of action, can not only postpone resistance produces, can also improve drug effect and residual period, reduce usage amount
Reduce cost, so we use second worm nitrile 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.
Summary of the invention

Analyze above-mentioned data, measurement result shows that when second worm nitrile and multiple killing teichomycin different proportion were composite, the co-toxicity coefficient of prescription all had tangible addition and synergistic effect all greater than 80.Wherein fill a prescription 3 and the prescription 4 co-toxicity coefficient maximums, be respectively 120.40 and 140.73.
By the indoor biometrics test, select the field trial that the bigger prescription of CTC 3, prescription 4 and the less prescription 1 of CTC are prevented and treated beet armyworm, determine the effect of prescription control beet armyworm; Simultaneously by with the contrast of the effect of second worm nitrile, the agent of multiple killing teichomycin list, verify the synergistic effect after composite.Concrete test method and data are as follows:
Test one:18% second worm nitrile, 3% multiple killing teichomycin WP, 15% second worm nitrile WDG, 2.5% multiple killing teichomycin WDG do the test of pesticide effectiveness of field control beet armyworm.Test site is Anqiu, Zhanhua city, Shandong Province, and the time is on August 30th, 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: 7d decides 10 wild cabbages of strain investigation behind the medicine in each sub-district, before the record dispenser, behind the medicine 1,5, the residual worm amount of 7d, calculates the insect population rate that goes down.
The effect table of table 10 prescription 3 and other chemical control beet armyworms
From above data as can be seen, under the situation of identical using dosage, 18% second worm nitrile, 3% multiple killing teichomycin be mixed than when the 6:1 behind medicine the 7d control rate can reach 96.1%, the effect that preventive effect is higher than 15% second worm nitrile and 2.5% multiple killing teichomycin list agent far away when using, 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 prescription 4 and other chemical control beet armyworms
From above data as can be seen, under the situation of identical using dosage, 15% second worm nitrile, 5% multiple killing teichomycin be mixed than when the 3:1 behind medicine the 7d control rate can reach 95.7%, the effect that preventive effect is higher than 15% second worm nitrile WDG and 5% multiple killing teichomycin list agent far away when using, 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 6% second worm nitrile 2% multiple killing teichomycin and other chemical control beet armyworms
From above data as can be seen, under the situation of identical using dosage, 6% second worm nitrile, 2% multiple killing teichomycin 7d control rate behind medicine can reach 86.1%, the effect when preventive effect is higher than 6% second worm nitrile 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 4 control beet armyworms is best, this also matches with the result of indoor biometrics, and (CTC is big more, synergistic effect is big more), verified also that simultaneously second worm nitrile and multiple killing teichomycin are by different proportion when composite, the effect that the control efficiency of beet armyworm all is better than second worm nitrile and multiple killing teichomycin list agent use, certain synergistic effect is arranged, prescription 4 with fill a prescription 3 under the situation of identical using dosage, because the cost of prescription 4 is lower than prescription 3, and control efficiency is suitable, therefore selects for use prescription 4 to be optimal proportioning.
By above-mentioned three field control effectiveness tests, can determine to fill a prescription 4 for preventing and treating the more suitable prescription of paddy rice beet armyworm, 15% second worm nitrile, 5% multiple killing teichomycin is mixed than being 3:1(prescription 4) carried out further test, filter out the optium concentration of control beet armyworm.Experimental scheme 4g/ mu, 5g/ mu, 6g/ mu and 4 concentration tonsures of 7g/ mu are also done contrast with the effect of 15% second worm nitrile (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 4 different amounts control beet armyworm 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, 15% second worm nitrile, 5% multiple killing teichomycin WDG consumption is a 5g/ mu, the insect population rate of going down of 7d is 96.4% behind the medicine, and apparently higher than 15% second worm nitrile and 5% multiple killing teichomycin, difference is extremely remarkable; Go down rate and mu consumption of the insect population of mu consumption when being 6g and 7g is that the insect population rate of going down of 5g does not have significant difference, considers the problem of cost, and recommending 15% second worm nitrile, 5% multiple killing teichomycin WDG consumption is 5g/ mu control beet armyworm.
