Description
Technical field
The present invention relates to a kind of Pesticidal combination, including fluorine worm pyrrole quinoline and fenvalerate；Particularly relate to a kind of method controlling agricultural pests.
Background technology
Chemical prevention is agriculturally prevention and the important means controlling insect.But, currently, due to the kind of insect etc., living nature, weak effect that living environment etc. causes, repellence are strong etc., and reason can not effectively be prevented and kill off sometimes.Particularly the harmful organism for Lepidoptera, coleoptera, Diptera, Homoptera, Semiptera, Hymenoptera, Thysanoptera, Arachnoidea and Nematoda etc., utilizes conventional dose to carry out prevention and control and just becomes increasingly difficult.Therefore, need to seek a kind of new means and method to enable effectively to prevent and kill off harmful organism that is that can not prevent and kill off or that prevent and kill off difficulty.
The insects such as thrips, aleyrodid, aphid, scale insect, pink bollworm, bollworm, Pieris rapae, turnip aphid, vegetable aphid, red spider, bridging worm, cotton plant bug, tea geometrid, Euproctis pseudoconspersa, pink tea rust mite, leaf wart demodicid mite, Citrus leaf moth, Fructus Citri tangerinae aphid, Citrus tetranychid, phyllocnistis citrella stainton, rust mite, small heart-eating peach worm and oriental fruit months are insect common on the crops such as Oryza sativa L., Semen Tritici aestivi, Semen Maydis, Cotton Gossypii, vegetable, fruit tree, Folium Camelliae sinensis.If insect not being carried out corresponding measure, then the growth of crops must be affected.
Fluorine worm pyrrole quinoline (Pyrifluquinazon), chemical name is: (1-acetyl group-1, and 2,3,4-tetrahydrochysene-3-[(3-pyridylmethyl) amino]-6-[1,2,2,2 ,-four fluoro-1-(trifluoromethyls) ethyl] quinazoline-2-ketone；Fluorine worm pyrrole quinoline is known, and is described in such as EP1097932；Its molecular structural formula is:
Fluorine worm pyrrole quinoline, by the exploitation of pesticide company of Japan, belongs to a kind of new quinazoline (metadiazine) insecticides.Fluorine worm pyrrole quinoline is generally applied with water dispersible granules, and its mechanism of action is to make insect stop taking food and then hungry to death, thus preventing plant tissue from suffering more infringement, controls the propagation of some important diseases simultaneously.At present, the aleyrodid on preventing and treating vegetable, fruit tree and Folium Camelliae sinensis, aphid and scale insect it are mainly used in.
Fenvalerate (Fenvalerate), chemical name (RS)-alpha-cyano-3-phenoxy benzyl (RS)-2-(4-chlorphenyl)-3 Methylbutanoic acid ester, its molecular structural formula is:
Insect is mainly action of contace poison by fenvalerate, also has stomach toxicity and ovicidal action, but without fumigation action and systemic action.Fenvalerate insecticidal spectrum is wide, to various pests on Cotton Gossypii, vegetable, fruit tree, tea, cigarette, Semen sojae atricolor, wheat and barley, trees, flowers such as coleoptera, Diptera, single wing order, Semiptera, Lepidoptera and orthoptera pest, there is good prevention effect such as Pyrausta nubilalis (Hubern)., aphid, pollen beetle, lopper worm, cabbage butterfly, carpocapsa pononella, apple aphid, cotten aphid, small heart-eating peach worm etc..But the preventive effect of demodicid mite class, a red-spotted lizard class and mirid pentatomid is very poor.
Fenvalerate effect is rapid, knocks down power strong.At present, although number of pest can be suppressed owing to being used alone fenvalerate for a long time to rise when insect early period of origination uses, quick-acting is better, but when insect occurs in a large number, just loses control of its quantity, and therefore lasting effect is not good, is easily generated resistance；And the mechanism of action of fluorine worm pyrrole quinoline is to make insect stop taking food and then hungry to death, relatively slowly but lasting effect is better for quick-acting comparatively speaking.
The typical demand occurred in field of pest control is to need to provide a kind of pest control agent, it can reduce close rate and the reduction of active component or avoid hostile environment or toxicological effects on the one hand, still allow for effective Pest control simultaneously, can be combined with knocking down activity and lasting effect on the other hand, namely can in conjunction with snap action and long-acting.
Another difficulty using insecticide is in that, repeats and uses single Pesticidal compound to cause in many cases described reactive compound produces quick selection that is natural or that adapt to drug-fast insect uniquely.Accordingly, it would be desirable to contribute to preventing or overcome drug-fast pest control agent.

Biological test example
The combination of active principles of difference pesticide is made pesticide, is develop and develop novel pesticide at present and prevent and treat a kind of effective and quick way of agriculturally resistant insect.After the pestsides synthesis of different cultivars, typically exhibit three kinds of type of action: summation action, potentiation and antagonism.But it is specially which kind of effect, it is impossible to prediction, only just be can know that by great many of experiments.The good formula of compound synergic, owing to significantly improving actual prevention effect, what reduce pesticide makes consumption, thus greatly having delayed the generation speed of pest resistance to insecticide, is the important means of integrated control disease.
Inventor is by substantial amounts of screening test, the different ratio of fluorine worm pyrrole quinoline and fenvalerate lot of experiments and effectiveness analysis have been carried out, find in certain ratio range, obtained Pesticidal combination has gain effect, and be not only that the simple of two kinds of medicaments is added, specifically illustrate by implementation below.
Adopt the mode that Toxicity Determination and insecticidal test combine in embodiments of the present invention, first pass through Toxicity Determination, 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 potentiation, carries out insecticidal test on this basis again.
Test method: respectively the Pesticidal combination reagent dilutions joined in above-described embodiment is become five series concentration during test, be respectively placed in beaker standby.Then the method that first leaching leaf is followed by worm is adopted, take out after blade of the same size not in contact with any medicament is soaked 5s in the medicinal liquid configured, naturally dry, put in insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process 3 times and repeat, often repeating examination borer population used is 20, sets blank simultaneously, checks dead borer population in 72h, calculate mortality rate and corrected mortality, try to achieve virulence regression equation and calculate LC50Value.If comparison mortality rate is more than 10%, then it is considered as invalid test.Computing formula is as follows:
Live before mortality rate (%)=(borer population of living after borer population-medicine of living before medicine)/medicine borer population * 100
Corrected mortality (%)=(process group mortality rate-matched group mortality rate)/(100-matched group mortality rate) * 100
To be converted into probit value (y) for examination insecticide corrected mortality, concentration for the treatment of (μ g/ml) converts logarithm value to (x), draws virulence regression equation with method of least square, and thus calculates the value of every kind of medicament.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (with fluorine worm pyrrole quinoline for standard agent, its toxicity index is 100):
Actual measurement toxicity index (ATI)=(standard agent LC50/ reagent agent LC50) × 100
The percentage composition of B in the percentage composition+B medicament ATI × mixture of A in theoretical toxicity index (TTI)=A medicament ATI × mixture
Co-toxicity coefficient (CTC)=(mixture ATI/ mixture TTI) × 100

Efficiency test
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is individually used, there is collaborative parasite killing and acaricidal action.The predictive role of the particular combination of two kinds of reactive compounds can use so-called " Colby formula " (referring to S.R.Colby, " CalculatingSynergisticandAntagonisticResponsesofHerbicid eCombinations ", Weeds1967,15,20-22) calculated as below: if
X kills rate when to use consumption be mg/ha or reactive compound A that concentration is mppm, is expressed as accounting for the percentage rate of untreated control,
Y kills rate when to use consumption be ng/ha or reactive compound B that concentration is nppm, is expressed as accounting for the percentage rate of untreated control,
E kills rate when to use consumption be m and ng/ha or reactive compound A and B that concentration is m and nppm, is expressed as accounting for the percentage rate of untreated control,
So
