Description
Technical field
What the present invention relates to is a kind of Pesticidal combination, comprises the first active component spiral shell mite dibasic acid esters and the second active component pyridaben, particularly relates to disinsection method.
Background technology
Mite class is commonly called as two spotted spider mite, belongs to arachnoide pest, and be one of the important pests of the various crop such as fruit tree, cotton, Solanaceae, vegetables and ornamental flower of causing harm, common harmful mite belongs to Acariformes and Acarina more.Mite class mainly causes harm the leaf of plant, stem and flower etc., and thorn inhales the cauline leaf of plant, and there is the yellowish-brown point of a large amount of needle point size chlorosis in initial stage leaf front, and anaphase blade starts chlorosis from the bottom up and crispaturas, even comes off.Sometimes occur from blade in the middle part of plant, blade turns yellow gradually, come off.Harmful mite occurs many from generation to generation, and fertility is strong, and under suitable temperature and humidity conditions, energy mite population within a short period of time can be doubled and redoubled rapidly, causes very large harm to crops.Evil mite easily develops immunity to drugs to acaricide agent, if do not prevented and not treated in time when serious generation, the blade of the crop that is injured can chlorosis turn white, and withers and falls in advance.Under the torrid zone and greenhouse experiment, the whole year all can occur.The height of temperature determines the number of the growth cycle of each worm state of mite class, reproduction speed and egg laying amount.The weather conditions of extreme arid torrid climate often cause it to occur in a large number.
Because mite class generating capacity is large, the breeding cycle is short, hidden, and resistance rises fast, is difficult to control, so use chemical pesticide preparation to remain the main method of mite evil in control agricultural production.
Spiral shell mite dibasic acid esters (Spirobudiclofen), chemical name is: 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro [4, the 5]-last of the ten Heavenly stems-3-alkene-4-base carbonic acid dibutyl ester.Its molecular structural formula is formula I:
(formula I)
Spiral shell mite dibasic acid esters is a kind of Novel special window acids insecticide, and insecticidal spectrum is wide, and the lasting period is long.It causes dead larvae by the fatty biosynthesis of interference insect.And without cross resistance between existing miticide.Due to the mechanism of action of its uniqueness, the pest mite class existing insecticide being produced to resistance effectively can be prevented and treated.This medicament insecticidal spectrum is wide, strong adaptability, can be used for preventing and treating the sucking pest on the solanaceous crops such as fruit tree and eggplant, capsicum, tomato such as citrus, grape, apple, pears: two spotted spider mite, yellow spider, yellow tea mite, Tetranychus cinnabarinus, wood louse, trialeurodes vaporariorum etc.; Particularly strong to fertility and easily have good killing effect the pear sucker of shelter harm, two spotted spider mite.Spiral shell mite dibasic acid esters ovicidal effect is excellent especially, if also have good action of contace poison to children mite simultaneously, and the lasting period is long.But spiral shell mite dibasic acid esters has one-tenth mite weak effect, the defect that quick-acting is poor.
Pyridaben (Pyridaben), chemical name is the 2-tert-butyl group-5-(4-tert-butyl group benzylthio)-4-chlorine pyridazine-3-(2H) ketone, its structural formula is formula (II):
(formula II)
Pyridaben is contact killing type agent for killing mite and pest.To tetranychid, Panonychus citri, unguiculus mite, the beginning tetranychid, goitre mite and tarsonemid etc. all have good control efficiency.If each developmental stage of pyridaben to young mite mite, mite such as one-tenth mite and ovum etc. is all effective, rapid, respond well to the mite effect of active stage.Field efficacy can maintain 30 ~ 40 days, even longer, and its drug effect temperature influence is little.Also effective to suckings pest such as a red-spotted lizard class nymph, aleyrodid nymph, leafhopper, plant hopper, thrips and aphids.Under typical concentrations to oranges and tangerines, apple, pears, peach, grape, plum, cherry, apricot, strawberry, wild cabbage, tomato, capsicum, pimento, cucumber, watermelon, melon, garlic, lettuce, corn, paddy rice, wheat, rape, cotton, tobacco, tea, mulberry, potato, soybean, clover, dahlia, rose and sweet-scented oleander etc. all without poisoning, have slight poisoning to eggplant.It is safer to natural enemies such as ladybug, Chrysopa and parasitic wasps.Because reuse pyridaben in a large number, make mite class serious to this single dose pesticide resistance, do not reach satisfied control efficiency.
Nowadays, pyridaben is using as miticide agriculturally all, being used alone pyridaben at mite class initial stage of origination can effectively suppress mite class quantity to rise, quick-acting is better, but when mite class occurs in a large number, As time goes on pyridaben just loses control of its quantity gradually, makes the lasting period be no more than 20 days, and a drug can only play the effect controlling generation mite evil.
Spiral shell mite dibasic acid esters has the feature of lasting period length, first medication need be there is in mite class, but not easily hold this period, by the time need to be generally that mite class lays particular stress on generation during medication, and spiral shell mite dibasic acid esters quick-acting very slow, be that 7-10 talent reaches peak mortality after medicine to mite class onset time.
The activity of described individually oriented compound is good; But they are not to meet the high request that insecticide, miticide or nematocide must meet at low rate of application or when using for independent insect.
The urgent demand occurred in field of pest control is: need to provide a kind of Pesticidal combination, and it is reducing rate of application and reduction of active component or still can provide effective control of insect while avoiding hostile environment or toxicological effects; And this Pesticidal combination also needs to combine the snap action to insect and long-acting.
Another difficulty of use of insecticide is repetition and uses single Pesticidal compound to cause in many cases producing natural to described reactive compound or adapting to the quick selection of drug-fast insect uniquely.Therefore, need and help overcome drug-fast Pesticidal combination.
Therefore, the object of this invention is to provide a kind of Pesticidal combination, it solve at least above-mentioned a kind of problem: as reduced rate of application, improving activity profile, in conjunction with quick-acting and lasting effect, delaying drug resistance.

Inventor is by a large amount of screening tests, lot of experiments and effectiveness analysis have been carried out to the different ratio of spiral shell mite dibasic acid esters and pyridaben, find in certain ratio range, the Pesticidal combination obtained has gain effect, and be not only the simple addition of two kinds of medicaments, be specifically described with following embodiment.
Adopt the mode that Toxicity Determination and insecticidal test combine in embodiments of the present invention, first Toxicity Determination is passed through, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC<80 is anti-effect short of money, 80≤CTC≤120 are summation action, CTC > 120 is synergistic effect, carries out insecticidal test more on this basis.
Computing formula is as follows:
Live before lethality (%)=(borer population of living after borer population-medicine of living before medicine)/medicine borer population * 100
Corrected mortality (%)=(processed group lethality-control group lethality)/(100-control group lethality) * 100
To be converted into probit value (y) for examination insect corrected mortality, concentration for the treatment of (μ g/ml) converts logarithm value (x) to, calculates concentration LC in suppression with method of least squares
50, then calculate co-toxicity coefficient (CTC) according to the abundant method of Sun Yun.Computing formula following (with spiral shell mite dibasic acid esters for standard agent, its toxicity index is 100):
Actual measurement toxicity index (ATI)=(standard agent LC
50/ reagent agent LC
50) × 100
In theoretical toxicity index (TTI)=A medicament ATI × mixture A percentage composition+B medicament ATI × mixture in the percentage composition of B
Co-toxicity coefficient (CTC)=(mixture ATI/ mixture TTI) × 100

Test evaluates SOP (insecticide volume) with reference to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.7-2006) and initiative pesticide bioactivity, adopts infusion process.Citrus leaflet tablet band handle is cut, inserts in the peace added water and cut open in bottle.Connect the one-tenth mite of some.Wait becoming mite to lay eggs after 24h, removing into mite, the blade with abundant ovum is dipped in 10s in liquid, sucking unnecessary liquid with blotting paper rapidly, blade being placed in again peace and cuing open bottle, naturally dry.Be placed in observation ward and cultivate.Test repetition 4 times, and establish blank, investigate after contrasting all hatchings.Dead worm is considered as with the young mite that can not hatch He can not normally creep during investigation.
Table 1
From table one, control citrus red mite, when the proportioning of spiral shell mite dibasic acid esters and pyridaben is in the scope of 100:1 ~ 1:100, co-toxicity coefficient is all greater than 120, and the mixture of both explanations within the scope of this all shows as gain effect.
Test two: spiral shell mite dibasic acid esters and pyridaben are to the Toxicity Determination of oranges and tangerines leaf mining first
Adopt the method connecing worm after first soaking leaf, take out after the blade of the same size not contacting any medicament is soaked 5s in the liquid prepared, naturally dry, put into insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process and repeat for 3 times, often repeating examination borer population used is 20, establishes blank simultaneously, checks dead borer population in 72h, calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC50 value.If contrast lethality is greater than 10%, be then considered as invalid test.
Table 2
As known from Table 2, control oranges and tangerines leaf mining first, when the proportioning of spiral shell mite dibasic acid esters and pyridaben is in the scope of 100:1 ~ 1:100, co-toxicity coefficient is all greater than 120, and the mixture of both explanations within the scope of this all shows as gain effect.
Test three:
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is used separately, there is collaborative desinsection and acaricidal action.The predictive role of the particular combination of two kinds of reactive compounds can use so-called " Colby formula " (see S.R.Colby, " CalculatingSynergisticandAntagonisticResponsesofHerbicid eCombinations ", Weeds1967,15,20-22) calculate as follows: if
X is the kill ratio when using the reactive compound A that consumption is mppm for mg/ha or concentration, is expressed as the percentage accounting for untreated control,
Y is the kill ratio when using the reactive compound B that consumption is nppm for ng/ha or concentration, is expressed as the percentage accounting for untreated control,
E is when using consumption for kill ratio during m and ng/ha or the concentration reactive compound A and B that is m and nppm, being expressed as the percentage accounting for untreated control,
So
If the desinsection lethality rate of reality exceedes calculated value, then the lethal effect of composition be super add and, namely there is synergy.In this case, the kill ratio actually observed must be over the value of the expection kill ratio value (E) using above-mentioned formulae discovery.
