Description
The application is for dividing an application, and original application is the patent application " a kind of microbicide compositions that contains the active ingredient of Carbatene " of Zhang Shaowu, and the application number of original application is: 200710018862.7, and original application day is 2007.10.15.
Technical field
The agriculture chemicals fungicide composition that the present invention relates to, particularly a kind of microbicide compositions that contains the active ingredient of Carbatene.
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, carbendazim, benomyl are three kinds of more common systemic fungicides, belong to benzimidazole; Its main mechanism is to disturb the formation of spindle in the mitosis of bacterium, thereby influences the cell division of bacterium, prevents and treats disease drug resistance in recent years separately and obviously strengthens, and causes its preventive effect very poor.
Nitrile bacterium azoles, Difenoconazole, propiconazole, Tebuconazole, own azoles alcohol; These five kinds all belong to triazole bactericidal agent, can prevent and treat the caused disease of sac fungi, basidiomycetes and imperfect fungus, are sterol demethylation inhibitor; The content of these five kinds of compositions is more on the low side in the market; Though all belong to broad-spectrum germicide, owing to use for many years, single use preventive effect obviously descends directly influences the high yield of grain.
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 single use, preventive effect is slow.
Ring spot, anthracnose, spot defoliation are diseases more common on the various crop, usually cause crushing disaster.Particularly spot defoliation is prevented and treated difficulty, especially in zone, the north, and annual generation.In some serious zone, the conventional pesticide composition uses separately and be difficult to control, and effect is very poor.
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 exploitation of new active ingredient exists cost high again, the defective that the construction cycle is long.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 superior to the effect of two kinds of single agent.Show the result of 1+1＞2.
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 superior to a kind of microbicide compositions that contains the active ingredient of Carbatene of two kinds of single agent.
In order to overcome the defective that prior art exists; Technical solution of the present invention is achieved in that a kind of microbicide compositions that contains the active ingredient of Carbatene, and substantive distinguishing features that it is outstanding and obvious improvement are that said microbicide compositions comprises that active ingredient components A and active ingredient components B form; Wherein active ingredient components A is the active ingredient of Carbatene; Active ingredient components B is at least a following bactericide, and its bactericide is thiophanate-methyl, carbendazim, nitrile bacterium azoles, Difenoconazole, propiconazole, Tebuconazole, own azoles alcohol, polyoxin or benomyl; Is 50: 1～1: 50 by quality than the part by weight of active ingredient components A: active ingredient components B.
In order to prevent and treat more refractory ring spot, anthracnose, spot defoliation on the agricultural.Carried out mutual compositely with Carbatene A and different types of B composition, the ring spot on the crop, anthracnose, spot defoliation have been carried out Toxicity Determination and used prescription screening with different proportionings.
Carbatene: be a kind of non-internal-absorting bactericide, can stop the sprouting of germ spore, suppress the elongation of germ germ tube, make germ can't infect plant tissue; Can be widely used in ring spot, spot defoliation, anthracnose and the downy mildew etc. of preventing and treating various crop.Facts have proved that this composition is not only active high, toxicity is low but also pollution-free to surrounding environment.
The former medicine of test medicine is that producer provides.This experiment adopts growth rate method to carry out; And be mixed into contrast with equivalent sterile water 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.Not only can prevent and treat the difficult ring spot that prevents on the agricultural, anthracnose, but also can prevent and treat the diseases such as spot defoliation on the fruit tree.
Be mixed with active component Carbatene A and different activities composition B ring spot, anthracnose and spot fallen leaves and virulence test data are seen table 1
Table 1
From table, can obviously find out Carbatene and thiophanate-methyl, carbendazim, nitrile bacterium azoles, Difenoconazole, propiconazole, Tebuconazole, own azoles alcohol, polyoxin or wherein any one combination of benomyl.Ring spot, anthracnose and spot defoliation to difficult control on the agricultural have synergistic effect clearly.
