Abstract
The invention discloses a sterilization composition containing ametoctradin and methoxyacrylates. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from ametoctradin; the active ingredient B is selected from any one of compounds as follows: azoxystrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, metominostrobin and pyraoxystrobin; the weight ratio of the active ingredient A to the active ingredient B is (1: 80) to (80: 1). According to the composition, a synergistic effect on various diseases harmful to agricultural production is achieved, the pesticide dose is reduced, the pesticide residues on crops are reduced, the environmental pollution is alleviated, the harm cannot be caused to human and livestock, the environmental compatibility is good, and the pesticide resistance cannot be easily generated for the diseases.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of bactericidal composition containing azoles mepanipyrim and methoxy acrylic on corps diseases.
Background technology
Azoles mepanipyrim (ametoctradin) is obtained interim registration in China, and azoles mepanipyrim is brand-new triazolo pyrimidine series bactericidal agent, for the downy mildew of prevention and control cucumber and grape crop.
Fluoxastrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, SSF 126 or azoles bacterium ester all belong to methoxy acrylic bactericide, are widely used in the disease of crops.
But in the real process of agricultural production, preventing and treating the problem that disease the most easily produces is the generation of disease drug resistance.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistance disease.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 sterilization is all additive effect, really have a synergistic effect composite seldom, especially synergistic effect very obviously, synergy ratio very high composite just still less.Through inventor's research, find azoles mepanipyrim and Fluoxastrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, SSF 126 or azoles bacterium ester can produce good synergistic effect after composite, and not yet open about azoles mepanipyrim and the composite relevant report of Fluoxastrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, SSF 126 or azoles bacterium ester.
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 azoles mepanipyrim and methoxy acrylic.
The bactericidal composition containing azoles mepanipyrim and methoxy acrylic that the present invention proposes contains 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 azoles mepanipyrim, active component B is selected from the one in Fluoxastrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, SSF 126 or azoles bacterium ester, and active components A and the preferred weight ratio of active component B are 1 ︰ 50 ~ 50 ︰ 1; More preferably the weight ratio of azoles mepanipyrim and Fluoxastrobin is 1 ︰ 30 ~ 30 ︰ 1, the weight ratio of azoles mepanipyrim and kresoxim-methyl or dimoxystrobin or orysastrobin is 1 ︰ 20 ~ 25 ︰ 1, the weight ratio of azoles mepanipyrim and SSF 126 is 1 ︰ 25 ~ 20 ︰ 1, and the weight ratio of azoles mepanipyrim and azoles bacterium ester is 1 ︰ 25 ~ 30 ︰ 1; The weight ratio that most preferably is azoles mepanipyrim and Fluoxastrobin is 1 ︰ 5 ~ 5 ︰ 1, the weight ratio of azoles mepanipyrim and kresoxim-methyl or dimoxystrobin or orysastrobin is 1 ︰ 4 ~ 9 ︰ 1, the weight ratio of azoles mepanipyrim and SSF 126 is 1 ︰ 9 ~ 4 ︰ 1, and the weight ratio of azoles mepanipyrim and azoles bacterium ester is 1 ︰ 5 ~ 11 ︰ 1.
The bactericidal composition containing azoles mepanipyrim and methoxy acrylic that the present invention proposes is for preventing and treating the purposes of disease on crops, and described crops comprise cereal crops, legume crop, fiber crop, sugar [yielding, melon crop, fruits crop, dry fruit crop, hobby crop, root crop, oil crop, flowers crop, medicinal crop, raw material crop, green manure pasture crop; Described disease comprises downy mildew, powdery mildew, epidemic disease, leaf mold, shot hole, scab, peronospora tabacina, anthracnose, spot defoliation, rust, rice blast, banded sclerotial blight, brown spot.
The weight ratio of active components A, active component B is 1 ︰ 80 ~ 80 ︰ 1.Conventionally in composition, the weight percentage of active component is gross weight 0.5%～90%, is preferably 5%～80%.According to different preparation types, active component content scope is different.Conventionally, liquid preparation contains 1%～70% 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 5%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
Bactericidal composition of the present invention can be by user before use through dilution or directly use.Its preparation can be prepared by common processing method known in those skilled in the art, after mixing with liquid flux or solid carrier by active substance, then add surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, defoamer, disintegrant, antifreeze etc.
