Abstract
The invention discloses the bactericidal composition of a kind of Quinoxyfen-containinsterilization, bactericidal composition containing active components A Yu active component B, active components A is selected from quinoxyfen, active component B is selected from any one compound following: thiophanate-methyl, Prochloraz or its salt, carbendazim, polyoxin, and the weight ratio of active components A and active component B is 1 80 ~ 60 1.Multiple diseases in various crop is had greater activity by the present composition, and has obvious potentiation, expands fungicidal spectrum, and has that dosage is little, resistance of rainwater washing against, the obvious feature of potentiation.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application in crop pest of the bactericidal composition of a kind of Quinoxyfen-containinsterilization.
Technical background
Quinoxyfen (Quinoxyfen), molecular formula: C15H8Cl2FNO, chemical name: 5,7-bis-chloro-4-quinolyl-4-fluorophenyl ethers, quinoxyfen is systemic fungicide, and has fumigation action, so contributes to the medicament reallocation whole plant.Quinoxyfen is growth signals agent interfering.Research shows, it, neither sterol biosynthesis inhibitor, is not again dhodh inhibitors.This product is protective fungicide, and mobility is good, it is possible to suppresses appresorium growth, does not have eradicant action.
Thiophanate-methyl, Prochloraz or its salt, carbendazim, polyoxin are all some common wide-spectrum bactericides, and the salt of Prochloraz includes the manganese salt of Prochloraz, mantoquita, zinc salt, and it also has good bactericidal activity, is agriculturally being widely used.
Summary of the invention
Quinoxyfen, thiophanate-methyl, Prochloraz or its salt, carbendazim, polyoxin single dose life-time service are likely to bring resistance to occur, degradation problem under drug effect, the bactericidal composition that the present invention proposes contains active components A and active component B, and appropriate surfactant and carrier.
A kind of bactericidal composition of Quinoxyfen-containinsterilization, containing active components A and active component B, active components A and active component B weight ratio are 1 80 ~ 60 1, described active components A is selected from quinoxyfen, active component B one in thiophanate-methyl, Prochloraz or its salt, carbendazim, polyoxin.Active components A and active component B preferably weight ratio are 1 60 ~ 40 1；The weight ratio being more preferably quinoxyfen and thiophanate-methyl is 1 30 ~ 51, the weight ratio of quinoxyfen and Prochloraz or its salt is 1 30 ~ 20 1, the weight ratio of quinoxyfen and carbendazim is 1 30 ~ 51, and the weight ratio of quinoxyfen and polyoxin is 1 20 ~ 20 1.
The bactericidal composition of described Quinoxyfen-containinsterilization is for preventing and treating the disease of crops, and described crops include cereal crops, legume crop, fibre crops, sugar crop, melon crop, fruits crop, dry fruit crop, hobby crop, root crop, oil crop, flower crop, medicinal crop, crop, green manure pasture crop.
Described disease includes rice blast, downy mildew, brown spot, leaf blight, banded sclerotial blight, powdery mildew, rust, epidemic disease, leaf spot, ring spot, spot defoliation, scab, anthrax, head blight, canker, gray mold, graywall, peach brown rot, smut, penicilliosis, green mould, sclerotiniose, bakanae disease.
In the present composition, the content of active component depends on amount of application when being used alone, and also depends on mixed ratio and the potentiation degree of a kind of compound and another kind of compound, simultaneously also relevant with target disease.In usual compositions, the weight percentage of active component is the 1%～90% of gross weight, it is advantageous to be 5%～80%.According to different preparation types, active component content scope is different.Generally, liquid preparation contains the active substance of by weight 1%～60%, it is preferred that be 5%～50%；Solid preparation contains the active substance of by weight 5%～80%, it is preferred that be 10%～80%.
The bactericidal composition of the present invention at least contains a kind of surfactant, active component dispersion in water when being beneficial to use.Surface-active contents is the 2%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
Surfactant selected by the bactericidal composition of the present invention is known in those skilled in the art: can be selected from one or more in dispersant, wetting agent, thickening agent or defoamer.According to different dosage form, can also containing stabilizer known in those skilled in the art, antifreeze etc. in preparation.
