example 180
[0050] Example 180% azoxystrobin · thiophanate-methyl wettable powder
[0051] Azoxystrobin 1%, thiophanate-methyl 79%, naphthalenesulfonic acid formaldehyde condensate 7%, sodium dodecylbenzenesulfonate 3%, bentonite to 100%, the mixture was jet milled to obtain 80% pyrimidine Bacteridine·thiophanate-methyl wettable powder.
[0052] A new embodiment is formed by replacing the effective active component thiophanate-methyl with carbendazim, polyoxamycin, prochloraz, and prochloraz manganese salt.

Abstract
The invention relates to a bactericidal composition containing mepanipyrim. The bactericidal composition is prepared from an active component A and an active component B, wherein the active component A is selected from mepanipyrim, the active component B is selected from one of thiophanate methyl, polyoxins, carbendazim and prochloraz, and the weight ratio of the active component A to the active component B is 1:80-80:1. The effective active components are added into corresponding auxiliaries to be prepared into wettable powder, water dispersible granules, a suspending agent, suspension emulsion, emulsion in water, microemulsion, microcapsule suspension and a microcapsule suspension-suspension agent; the bactericidal composition is used for preventing and controlling gray mold, powdery mildew, venturia inaequalis, downy mildew, a rice blast, a rust disease, anthracnose, a leaf spot disease, an epidemic disease, a brown spot, an alternaria leaf spot and damping-off, resists rainwater washing and has the significant synergistic effect.
Description
[0001] This application is a divisional application. The original application is a patent application of Shaanxi Welch Crop Protection Co., Ltd. "A fungicidal composition containing azoxystrobin". The application number of the original application is: 201210079456.2, and the original application date is 2012.3.23 . technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing azoxystrobin on crop diseases. technical background [0003] Azoxyprodil, English name: mepanipyrim, molecular formula: C 14 h 13 N 3 , Azoxystrobin is a pyrimidine fungicide. Azoxystrobin has a unique mechanism of action that inhibits the secretion of pathogenic bacteria proteins, including reducing the level of some hydrolytic enzymes. It is speculated that these enzymes and pathogenic bacteria enter the host plant and cause necrosis of memory tissues. [0004] Thiophanate-methyl, English name: thiophanate-...
