Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of bactericidal composition in crop pest of a kind of containing fluopyram and methoxy acrylic.
Technical background

2o.It suppresses mitochondrial respiratory by hindering the electro transfer of succinate dehydrogenase in respiratory chain.Reaching the object controlling pathogenic bacteria by suppressing the several stage in the growth of pathogenic bacteria cycle, being mainly used in broad leaf crop being prevented and treated the microbial disease of ascus.
The bactericide of methoxy acrylic is the outer inhibitor of quinone, by the electron transmission of block cell pigment b with cytochrome c 1, and suppression mitochondrial respiratory.Selectivity derives from the deesterify of plant corpus endoenzyme.There is protectiveness, therapeutic, eradicant and long residual effect, suppress spore germination.
In the real process of agricultural production, the problem that controlling 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 agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of synergy ratio.Study through inventor, find fluorine pyrrole bacterium acid amides and ZJ0712, pyraclostrobin, fluoxastrobin, Enestroburin, ZEN 90160, kresoxim-methyl mutually composite, there is good synergistic effect within the specific limits, and about fluorine pyrrole bacterium acid amides and ZJ0712, pyraclostrobin, fluoxastrobin, Enestroburin, ZEN 90160, kresoxim-methyl relevant composite, there is not yet relevant report at home and abroad at present.
Summary of the invention
The object of the invention is to propose a kind of bactericidal composition with synergistic function, use cost is low, preventive effect is good containing fluopyram and methoxy acrylic.
The present invention is achieved through the following technical solutions:
The bactericidal composition of a kind of containing fluopyram and methoxy acrylic, it is characterized in that 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 fluorine pyrrole bacterium acid amides, active component B is methoxy acrylic bactericide, and described methoxy acrylic bactericide is selected from any one compound following: ZJ0712, pyraclostrobin, fluoxastrobin, Enestroburin, ZEN 90160, kresoxim-methyl; The preferred weight ratio of active components A and active component B is 1 ︰ 60 ~ 40 ︰ 1; The weight ratio being more preferably fluorine pyrrole bacterium acid amides and ZJ0712 is 1 ︰ 10 ~ 25 ︰ 1, the weight ratio of fluorine pyrrole bacterium acid amides and pyraclostrobin is 1 ︰ 30 ~ 15 ︰ 1, the weight ratio of fluorine pyrrole bacterium acid amides and fluoxastrobin or Enestroburin or ZEN 90160 is 1 ︰ 25 ~ 10 ︰ 1, and the weight ratio of fluorine pyrrole bacterium acid amides and kresoxim-methyl is 1 ︰ 40 ~ 10 ︰ 1; The weight ratio most preferably being fluorine pyrrole bacterium acid amides and ZJ0712 is 1 ︰ 5 ~ 15 ︰ 1, the weight ratio of fluorine pyrrole bacterium acid amides and pyraclostrobin or fluoxastrobin or Enestroburin is 1 ︰ 10 ~ 5 ︰ 1, and the weight ratio of fluorine pyrrole bacterium acid amides and ZEN 90160 or kresoxim-methyl is 1 ︰ 15 ~ 5 ︰ 1.
Described containing fluopyram and the bactericidal composition of methoxy acrylic are for preventing and treating the disease of 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, flower crop, medicinal crop, crop, green manure pasture crop; Described disease comprises powdery mildew, anthracnose, spike rot, leaf spot, scab, rust, glume blight, net blotch, downy mildew, epidemic disease, leaf rust, moire disease, brown spot, leaf blight, smut.
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 synergistic effect degree of a kind of compound and another kind of compound, simultaneously also relevant with target disease.In usual composition, the weight percentage of active component is 1% ~ 90% of gross weight, is preferably 5% ~ 80%.According to different preparation types, active component content scope is different.Usually, liquid preparation contains the active substance of by weight 1% ~ 60%, is preferably 5% ~ 50%; Solid pharmaceutical preparation contains the active substance of by weight 5% ~ 80%, is preferably 10% ~ 80%.
At least containing a kind of surfactant in bactericidal composition of the present invention, the dispersion of active component in water when being beneficial to use.Surface-active contents is 2% ~ 30% of total formulation weight amount, and surplus is solid or liquid diluent.
Surfactant selected by 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, thickener or defoamer.According to different dosage form, in preparation, stabilizing agent known in those skilled in the art, antifreeze etc. can also be contained.
