Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of bactericidal composition containing chlorine nalidixic bacterium ester and triazole type in crop pest.
Technical background
Chlorine nalidixic bacterium ester: molecular formula is C

l3n
2o
4chemical name is N-methoxyl group-N-[2-[[(3,5,6-trichloropyridine-2-yl) oxygen] methyl] phenyl] methyl carbamate, belong to carbamate fungicide, outward appearance is pale solid, the same with the mechanism of action of other methoxy acrylic bactericide, chlorine nalidixic bacterium ester is also mitochondrial respiratory inhibitor, namely by suppressing the breathing of electronics transfer Mitochondria between cytochrome b and c, causes effect.
Own azoles alcohol, penconazole, cyproconazole and Flusilazole all belong to conventional triazole bactericidal agent, are widely used in the disease of crops.
In the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the drug-fast generation of germ.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistance germ.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, discovery is mutually composite by chlorine nalidixic bacterium ester and effective active composition B, there is within the specific limits good synergistic effect, and relevant composite about chlorine nalidixic bacterium ester and own azoles alcohol, penconazole, cyproconazole, Flusilazole, there is not yet at present relevant report at home and abroad.
Summary of the invention
The object of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect the is good bactericidal composition containing chlorine nalidixic bacterium ester and triazole type.
A kind of bactericidal composition containing chlorine nalidixic bacterium ester and triazole type, active ingredient is active components A and active component B, active components A and active component B weight ratio are 1:80～80:1, described active components A is selected from chlorine nalidixic bacterium ester, select oneself a kind of in azoles alcohol, penconazole, cyproconazole, Flusilazole of active component B, the preferred weight ratio of active components A and active component B is 1:40～40:1; More preferably: the weight ratio of chlorine nalidixic bacterium ester and own azoles alcohol, penconazole, cyproconazole, Flusilazole is 1:20～20:1, and the weight ratio of chlorine nalidixic bacterium ester and penconazole is 1:15～25:1; Most preferably be: the weight ratio of chlorine nalidixic bacterium ester and own azoles alcohol, cyproconazole, Flusilazole is 1:9～11:1, and the weight ratio of chlorine nalidixic bacterium ester and penconazole is 1:4～14:1.
The described bactericidal composition containing chlorine nalidixic bacterium ester, makes wetting powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion, microcapsule suspending agent or microcapsule suspension-suspending agent, and wherein chlorine nalidixic bacterium ester and Flusilazole also can be made into missible oil.
The disease of the described bactericidal composition containing chlorine nalidixic bacterium ester for preventing and treating crops, described crops comprise cereal crops, legume crop, oil crop, fiber crop, sugar [yielding, melon crop, fruits crop, dry fruit crop, hobby crop, root crop, flowers crop, medicinal crop, raw material crop and green manure pasture crop.
Described disease comprises stalk break, powdery mildew, false smut, rice blast, banded sclerotial blight, gray mold, scab, spot defoliation, brown rot, rust, black spot, smut, leaf spot, ring spot, white rot, anthrachose of grape, bakanae disease, damping off, loose kernel smut, rust or anthracnose.
The amount of application when content of active component depends on independent use in bactericidal composition of the present invention, also depends on mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound, and the while is also relevant with target disease.Conventionally in composition, the weight percentage of active component is gross weight 1%～90%, is preferably 5%～80%.According to different preparation types, active component content scope is different.Conventionally, liquid preparation contains 1%～60% active substance by weight, is preferably 5%～50%; Solid pharmaceutical preparation contains 5%～80% active substance by weight, is preferably 10%～80%.
In bactericidal composition of the present invention, at least contain a kind of surfactant, the dispersion of active component in water while being beneficial to use.Surface-active contents is 2%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
The selected surfactant of bactericidal composition of the present invention is known in those skilled in the art, by user before use through dilution or directly use its preparation, can be prepared by processing method known in those skilled in the art, after being about to active component and mixing with liquid flux or solid carrier, then add surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, defoamer etc.
