Abstract
The invention discloses a bactericide composite containing epoxiconazol used as an active ingredient. The bactericide composite comprises epoxiconazol used as an active ingredient A and bactericide used as an active ingredient B, wherein the active ingredient B bactericide comprises any one or two or more then two of thiophanate-methyl, carbendazim, mancozeb, zineb, metiram or polyoxin, the mass ratio of the active ingredient A epoxiconazol to the active ingredient B bactericide is (50-1):(1-50). The bactericide composite which particularly refers to a binary bactericide composite can be used for preventing and controlling damping off and powdery mildew difficultly prevented and controlled in agriculture, the bactericide composite can be applied in a spraying way after being diluted into 2,000-3,000 times; 72 hours after application, the field prevention effects on damping off and powdery mildew are 90.4% and 95.2% respectively; in contrast, 72 hours after being applied in the same way, emulsion in water prepared from a single active ingredient, particularly referring to 45 percent epoxiconazol, has prevention effects on damping off and powdery mildew of 30.8% and 21.2% respectively; and comparing the bactericide composite with the bactericide containing one single active ingredient, the prevention effect difference is up to 3-4 times.
Description
The application is for dividing an application, and original application is Zhang Shaowu application " a kind of microbicide compositions that contains the active ingredient of fluorine ring azoles ", and the application number of original application is: 200710018860.8, and original application day is 2007.10.15.
Technical field
The present invention relates to the agriculture chemicals fungicide composition, being specifically related to is a kind of microbicide compositions that contains the active ingredient of fluorine ring azoles.
Technical background
Existing agriculture chemicals fungicide is to form with single agent kind and additive combination mostly, and there is the relatively poor defective of prevention and elimination of disease and pests effect in this single agent kind, narrates the shortcoming of single agent kind below respectively:
Thiophanate-methyl: being a kind of common bactericide, belonging to benzimidazole, is a kind of broad spectrum activity systemic fungicide, can prevent and treat the various crop disease.Have interior suction, prevention and therapeutic action.In addition, prevent and treat disease drug resistance in recent years separately and strengthen, cause preventive effect to descend.
Carbendazim: also being a kind of common bactericide, belonging to benzimidazole, is a kind of high-efficiency low-toxicity, systemic fungicide.Its main mechanism is to disturb the formation of spindle in the mitosis of bacterium, thereby influences the fission process of bacterium.Single use preventive effect is not obvious.
Mancozeb: be a kind of common protectiveness that has than wide spectrum, can effectively prevent and treat damping off that various crop causes and powdery mildew etc.
Zineb: belong to the broad spectrum protection organosulfureous fungicide, can effectively prevent and treat damping off, powdery mildew and anthracnose that various crop such as vegetables, peanut, wheat class cause.
Carbatene: be a kind of non-internal-absorting bactericide, be used for leaf surface treatment and play the effect of protection sterilizing disease-preventing.Important germ such as ring spot, the downy mildew etc. of control on the agricultural.Facts have proved that this composition not only control efficiency is good, and free from environmental pollution.
Polyoxin: be the metabolite that streptomyces aureus produces, belong to the broad-spectrum antibiotics series bactericidal agent, have interior preferably absorption.Be a kind of efficient, the safety pesticide of low toxicity non-environmental-pollution, owing to belong to biologic product, and simple the use, preventive effect is slow.
Damping off and powdery mildew are diseases more common on the various crop, and especially in zone, the north, the annual generation usually caused the crushing disaster of crop.In some serious zone, crop strengthens conventional pesticide composition resistance, use separately to be difficult to control, and effect is very poor, has a strong impact on the good harvest of grain.
Go up the germ that produces resistance for control agricultural, a kind of way is to release the new component that new and existing kind do not have cross resistance.But the development cost height of new active ingredient, the construction cycle is long, and all produces the speed of resistance forever less than insect.
Summary of the invention
The purpose of this invention is to provide a kind of composition of different cultivars that adopts and be mixed, produce synergistic effect, make field control effect significantly be better than a kind of microbicide compositions that contains the active ingredient of fluorine ring azoles of two kinds of single agent.
In order to prevent and treat more refractory damping off and powdery mildew on the agricultural, technical solution of the present invention is achieved in that a kind of microbicide compositions that contains the active ingredient of fluorine ring azoles, its outstanding substantive distinguishing features and obvious improvement is to be made up of the fluorine ring azoles A and the bactericide B of active ingredient, its described bactericide B component is meant in thiophanate-methyl, carbendazim, mancozeb, zineb, Carbatene or the polyoxin any one or two or more combination, and fluorine ring azoles A and bactericide B press mass ratio 50～1: between 1～50.Carried out mutual composite efficiency raising scheme with fluorine ring azoles A and different types of B composition, damping off on the various crop and powdery mildew etc. have been carried out Toxicity Determination and used the prescription screening with different proportionings.Be that any one is combined as active ingredient with fluorine ring azoles A and B thiophanate-methyl, carbendazim, mancozeb, zineb, Carbatene or polyoxin, can prevent and treat agricultural and go up the damping off of difficult control and powdery mildew etc.
Fluorine ring azoles: be seldom common in the market a kind of bactericide, a series of cereal crop disease and damping off, powdery mildew etc. are had good preventive and therapeutic effect.It not only has good protection, treats and roots out activity, and inhales and stronger residual activity in having.
Test medicine provides for former pharmaceutical factory man.This experiment adopts growth rate method to carry out, and be mixed into contrast with equivalent aqua sterilisa and medium, calculate virulence equation and lethal concentration of 50 LC50 with method of least squares, calculate the toxicity index of medicament and the co-toxicity coefficient of using with (CTC method) according to the abundant method of Sun Yun, two kinds of different proportioning synergies of medicament are antagonism than it (SR) SR＜0.5,0.5≤SR≤1.5 are summation action, SR＞1.5 are synergistic effect.Therefore, identical for mechanism of action, the composition of different cultivars is mixed, and is a kind of selection of the best.If reasonable proportioning is arranged, usually can produce synergistic effect.Make field control effect significantly be better than the effect of two kinds of single agent.Show the result of 1+1＞2.Its beneficial effect sees Table 1, table 2.
