Problems solved by technology

[0006] At present, there is no bibliographic report on the mixed control of downy mildew and blight of pyrimidine tetrazole and methoxy acrylate fungicides syringstrobin, oxafeconone, and midazolone. Further experiments have found that , compounding pyrimidine tetrazole with different mechanism of action and methoxy acrylate fungicides syringstrobin, oxafluconone, and midazolidone has unexpected effects, not only the synergistic effect is remarkable , can also significantly improve the control effect of downy mildew and blight on crops, reduce the dosage of pesticides, reduce the cost of control, and improve the safety of crops

Embodiment 1

[0060] Weigh 30% pyridazole tetrazole, 15% syringstrobin, 5% alkylphenol polyoxyethylene ether phosphate, 4% alkylnaphthalene sulfonate formaldehyde condensate, 5% sodium lauryl sulfate, Kaolin is added to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 45% tetrazolin-syringstrobin wettable powder.

Embodiment 2

[0062] Weigh 25% tetrazole pyridoxine, 10% oxaflumedone, 4% alkylnaphthalene formaldehyde condensate sodium sulfonate, 7% alkylnaphthalene sulfonate formaldehyde condensate, 8% alkylnaphthalene sulfonate, White carbon black is added up to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 35% tetrazole pyramidine · oxaflucone wettable powder.

Embodiment 3

[0064] Weigh 15% pyrimidine tetrazole, 10% imidazolidin, 5% polycarboxylate TERSPERSE 2700, 4% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 4% pull-off powder BX (two sodium butylnaphthalene sulfonate), 4% sodium dodecylbenzenesulfonate, and attapulgite to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 25% tetrazolidin.

Abstract

The invention discloses sterilization composition containing picarbutrazox and an application of the sterilization composition. Effective active components comprise a first active component, namely, picarbutrazox and one of second active components, namely, strobilurin bactericides including coumoxystrobin, famoxadone and fenamidone, and the weight ratio of the first active component to the second active component is 1:80-60:1, preferably(1:60)-(40:1). The composition can be prepared in forms of agriculturally allowable wettable powder, water dispersible granules, suspending agents, suspension emulsions, emulsions in water, microemulsions, microcapsule suspending agents, microcapsule suspension-suspending agents, dispersible oil suspending agents and dry suspending agents. The composition comprises reasonable components and has a good sterilization effect, the activity and the sterilization effect of the composition are not simple superposition of the activity of the components, and compared with an existing single preparation, the composition has the significant sterilization effect, has the significant synergistic effect and is safe to crops. The composition has significant control effects on downy mildew and phytophthora diseases in crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of the first active component pyrimidine tetrazole and the second active component methoxyacrylate fungicides syringstrobin, oxaflucone, and midazolidone and an auxiliary agent composition and belongs to the technical field of compound pesticides. Background technique [0002] Pyramide tetrazole, English name picarbutrazox, is a carbamate fungicide developed by Japan Soda Corporation. At present, the mechanism of action of pyrimidine tetrazole is not clear, and the International Fungicide Resistance Committee (FRAC) classifies it as an independent U17 category. Pyridine tetrazole at a dose of 50ppm has a significant effect on diseases caused by downy mildew, blight and Pythium, focusing on prevention and protection, and has cross-layer systemic and certain therapeutic activity. [0003] Syringstrobin, English name coumoxystrobin, chemical name: (E)-2-(2-((3-butyl-4-methyl-coumarin...
