[0051] Example 18 0% azoxystrobin·thiophanate-methyl wettable powder

[0052] Azoxystrobin 1%, thiophanate methyl 79%, naphthalenesulfonic acid formaldehyde condensate 7%, sodium dodecylbenzene sulfonate 3%, and bentonite added to 100%, the mixture is jet-pulverized to obtain 80% pyridine Bacteryl thiophanate methyl wettable powder.

[0053] The effective active component thiophanate-methyl was replaced by carbendazim, polyoxin, prochloraz, and prochloraz manganese salt to form a new example.

Abstract

The invention relates to a bactericidal composition containing mepanipyrim. The bactericidal composition contains an active component A and an active component B, the active component A is selected from mepanipyrim, the active component B is selected from one of thiophanate methyl, polyoxin, carbendazim, prochloraz and salts thereof, wherein the weight ratio of the effective active component A to the effective active component B is 1:80-80:1. The effective active components are added with corresponding auxiliary agents to prepare a wettable powder, a water dispersible granule, a suspending agent, a suspending emulsion, an aqueous emulsion, a microemulsion, a microcapsule suspending agent, and a microcapsule suspension-suspending agent. The bactericidal composition are used for prevention and treatment of gray mold, powdery mildew, scab, downy mildew, rice blast, rust disease, anthracnose, leaf spot, pestilence, brown spot, alternaria mali roberts and damping-off disease, and have rainwater washing resistance and obvious synergic effect.

Description

Technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a bactericidal composition containing azoxystrobin on crop diseases. technical background [0002] Mepanipyrim, English name: mepanipyrim, molecular formula: C 14 H 13 N 3 Azoxystrobin is a pyrimidine fungicide, and azoxystrobin has a unique mechanism of action that inhibits the secretion of pathogenic bacteria protein, including reducing the level of some hydrolytic enzymes. It is speculated that these enzymes and pathogenic bacteria enter the host plant and cause the necrosis of the memory tissue. [0003] Thiophanate-methyl, English name: thiophanate-methyl, molecular formula: C 12 H 14 N 4 O 4 S 2 , Chemical name: 1,2-bis-(3-ethoxycarbonyl-α-thiourea)benzene. Thiophanate methyl belongs to the benzimidazoles, which is a broad-spectrum systemic fungicide, which can prevent and treat a variety of crop diseases and has systemic, preventive and therapeutic effects. It...
