Description
Technical field
The application is related to pesticide field, specifically, is related to a kind of composition pesticide and its preparation and application.
Background technology
Rynaxypyr (Chlorantraniliprole), molecular formula is C18H14BrCl2N5O2, chemical structural formula is as follows
It is shown：
Rynaxypyr is a kind of insecticide of high-efficiency broad spectrum, to diamond-back moth section, Noctuidae, Pyralidae, the moth of Lepidoptera
Guo E sections, tortricid, miller section, Gelechidae, Gracilariidae etc. have good control effect, moreover it is possible to control coleoptera weevil
Section, Chrysomelidae；Diptera Agromyzidae；Various non-lepidoptera pests such as Bemisia tabaci.
But a large amount of now with Rynaxypyr use, some agricultural pests include diamondback moth, beet armyworm, cotton boll
Worm etc. is on the rise to its resistance, causes to use the dosage of Rynaxypyr to increase, and not only increases cost accounting, and
Pollution to environment is also more serious.
In consideration of it, special propose the application.
The content of the invention
The primary goal of the invention of the application is to propose a kind of composition pesticide.
Second goal of the invention of the application is to propose the preparation containing the composition pesticide.
3rd goal of the invention of the application is to propose the application containing the composition pesticide.
In order to complete the purpose of the application, the technical scheme for using for：
The application is related to a kind of composition pesticide, contains Rynaxypyr and 3- hydroxyls -4-methoxybenzaldehyde contracting ammonia
Base thiocarbamide.
Preferably, Rynaxypyr and the mass ratio of 3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones are 5~15：
1。
Preferably, Rynaxypyr and the mass ratio of 3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones are 8~12：
1。
The application further relates to a kind of preparation containing composition pesticide, it is characterised in that the formulation of the preparation be pulvis,
Granula, suspending agent, finish.
Preferably, containing also galenic pharmacy acceptable carrier in the preparation.
The application further relates to the composition pesticide for killing lepidoptera imago and its larva, coleoptera adult and its children
Application in worm, Diptera adult and its larva.
Preferably, the Lepidoptera includes diamond-back moth section, Noctuidae, Pyralidae, Carposinidae, tortricid, miller section, wheat
Moth section and Gracilariidae；The coleoptera includes Culculionidae and Chrysomelidae；The Diptera is Agromyzidae.
Preferably, the diamond-back moth section includes diamondback moth；Noctuidae includes that beet armyworm, lopper worm, bollworm, small ground are old
Tiger and mythimna separata etc..
The technical scheme of the application at least has following beneficial effect：
The application by using 3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones as Rynaxypyr synergist,
The synergistic function that it has can improve prevention effect of the Rynaxypyr to insects such as Lepidoptera, coleoptera, Dipteras,
With good market development application prospect.
Specific embodiment
With reference to specific embodiment, the application is expanded on further.It should be understood that these embodiments are merely to illustrate the application
Rather than limitation scope of the present application.
The application is related to a kind of composition pesticide, and Rynaxypyr and 3- hydroxyl -4- methoxies are contained in composition pesticide
Benzaldehyde thiosemicarbazones.The application has found that 3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones is used as chlorine worm by studying
The synergist of benzamide, has synergistic function to Rynaxypyr, and application is merged by both, and it is right to substantially increase
The prevention effect of the insects such as Lepidoptera, coleoptera, Diptera, reduces the concentration for reaching and effectively killing insect, greatly reduces
The consumption of agricultural chemicals, not only with high economic worth, also protects environment, reduces residues of pesticides.
3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones (3-hydroxy-4-methoxy in the application
Benzaldehyde thiosemicarbazone) structural formula it is as follows：
The synthetic method and structural confirmation collection of illustrative plates of the material referring to document (《The synthesis of substituted benzaldehyde thiosemicarbazones and
Its inhibitory activity to insect phenol oxidase》, chemical reagent, 2007,29 (1):First industry of 34-36 solutions etc., 2007).
3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones can have strong inhibitory activity to insect phenol oxidase.Phenol
Oxidizing ferment (Phenoloxidase, PO) (EC.1.14.18.1) is baroque multi-subunit cupric oxidoreducing enzyme, is elder brother
A kind of important enzyme in polypide, plays an important role in the development by metamorphosis of insect and immune system, and it is anti-that it may participate in defence
Should and wound healing；The oxygen radical with CDCC and semiquinone and trioxyphenol with potential CDCC are produced,
Further enhance the immune defense ability of host.By suppressing the activity of insect phenol oxidase, can heavy damage insect it is immune
Ability, so as to reach the purpose of rationally control insect.3- hydroxyls -4-methoxybenzaldehyde thiosemicarbazones can efficiently suppress harmful
The activity of worm phenol oxidase, concentration (IC in its suppression50) up to 0.26 μm of ol/L.So as to the immune system to insect plays serious
Destruction, therefore the insecticidal effect of Rynaxypyr is significantly improved, strengthen Rynaxypyr virulence, play collaboration and increase
Effect is acted on.Especially the prevention effect of the insect resistant to Rynaxypyr is particularly evident.
Improved as one kind of the application composition pesticide, Rynaxypyr contracts with 3- hydroxyls -4-methoxybenzaldehyde
The mass ratio of thiosemicarbazides is 5~15：1.
Improved as one kind of the application composition pesticide, Rynaxypyr contracts with 3- hydroxyls -4-methoxybenzaldehyde
The mass ratio of thiosemicarbazides is 8~12：1.
Experiment discovery is carried out by coordinating both, by Rynaxypyr and 3- hydroxyls -4-methoxybenzaldehyde contracting ammonia
Base thiocarbamide is used cooperatively in the range of the mass ratio of the application, and its synergistic function is most strong.
The application further relates to a kind of preparation containing the composition pesticide, and said preparation can be all doses applied in agricultural chemicals
Type, it is preferred that can be pulvis, granula, suspending agent, finish.
Improved as one kind of the application composition pesticide, containing also galenic pharmacy acceptable carrier in preparation.Its formulation
Specifically chosen and carrier specifically chosen be those skilled in the art and grasp and well known.
The application further relates to the composition pesticide for killing lepidoptera imago and its larva, coleoptera adult and its children
Application in worm, Diptera adult and its larva.
Wherein, Lepidoptera include diamond-back moth section, Noctuidae, Pyralidae, Carposinidae, tortricid, miller section, Gelechidae and
