Embodiment 1

[0034] The pesticide water suspension formulation is: active ingredient 33.2% (17.7% azoxystrobin, 11.1% difenoconazole, 4.4% hexaconazole), wetting agent 1% sodium isopropyl naphthalene sulfonate, lauryl Sodium sulfate 0.5%, dispersant naphthalene sulfonate formaldehyde condensate 3%, polycarboxylate sodium salt 2%, defoamer organic silicone 0.3%, antifreeze agent ethylene glycol 2.5%, glycerin 2.5%, Thickener Xanthan Gum 0.2%, Magnesium Aluminum Silicate 2%, Preservative Cathone 0.2%, add water to make up 100%.

[0035] The preparation method is:

[0036] (1) Mix the pre-measured water, wetting agent, dispersant, defoamer and preservative according to the above formula, and then make it uniform by high-speed shearing;

[0037] (2) Add the pre-weighed active ingredients azoxystrobin, difenoconazole and hexaconazole to the mixture obtained in step (1) and disperse evenly with a dispersing disc;

[0038] (3) Put the mixture obtained in step (2) into a horizontal sand mill for...

Embodiment 2

[0041] The pesticide water suspension formulation is: active ingredient 33.2% (24.4% azoxystrobin, 4.4% difenoconazole, 4.4% hexaconazole), wetting agent sodium isopropyl naphthalene sulfonate 1%, lauryl Sodium sulfate 0.5%, dispersant naphthalene sulfonate formaldehyde condensate 3%, polycarboxylate sodium salt 2%, defoamer organic silicone 0.3%, antifreeze agent ethylene glycol 2.5%, glycerin 2.5%, Thickener Xanthan Gum 0.2%, Magnesium Aluminum Silicate 2%, Preservative Cathone 0.2%, add water to make up 100%.

[0042] The preparation method is the same as in Example 1.

Embodiment 3

[0044]The pesticide water suspension formulation is: active ingredient 33.2% (17.7% azoxystrobin, 13.3% difenoconazole, 2.2% hexaconazole), wetting agent sodium isopropyl naphthalene sulfonate 1%, lauryl Sodium sulfate 0.5%, dispersant naphthalene sulfonate formaldehyde condensate 3%, polycarboxylate sodium salt 2%, defoamer organic silicone 0.3%, antifreeze agent ethylene glycol 2.5%, glycerin 2.5%, Thickener Xanthan Gum 0.2%, Magnesium Aluminum Silicate 2%, Preservative Cathone 0.2%, add water to make up 100%.

[0045] The preparation method is the same as in Example 1.

Abstract

The invention discloses a fungicidal composition containing azoxystrobin, difenoconazole and hexaconazole and application thereof. With azoxystrobin, difenoconazole and hexaconazole being effective components, the fungicidal composition comprises, by weight, 1-30% of azoxystrobin, 1-25% of difenoconazole and 1-10% of hexaconazole. The composition is good in stability, can effectively bring advantages of the three effective components into full play, has an obvious synergistic effect, and has a prominent effect on prevention and control of almost all fungal diseases in wheat, corn, melons, rice, peanuts and other crops and especially plant diseases caused by basidiomycetes, deuteromycota, oomycetes and ascomycetes. The composition has a wide prevention and control spectrum and meanwhile has protecting and treating effects. In addition, through compounding of azoxystrobin, difenoconazole and hexaconazole, the dosage of effective components can be reduced, resistance to the fungicidal composition by pathogenic bacteria can be delayed, natural enemies are effectively protected, and the fungicidal composition has important economic significance, environmental protection significance and ecological significance for comprehensive prevention and control of pests.

Description

technical field [0001] The invention discloses a pesticide compound bactericidal composition, in particular a bactericidal composition of azoxystrobin, difenoconazole and hexaconazole and application thereof. Background technique [0002] Azoxystrobin is a methoxyacrylate (Strobilurin) fungicidal pesticide. The appearance of the original drug is off-white to yellow solid (the higher the content, the better the fineness, and the lighter the color), it has the characteristics of high efficiency and broad spectrum. By binding to the Qo site of cytochrome b on the mitochondria, it blocks the electron transfer between cytochromes and inhibits the respiration of mitochondria to play a role in destroying the energy synthesis of pathogens. The product has good activity against almost all fungal diseases (Ascomycotina, Basidiomycotina, Flagellate and Deuteromycotina) diseases such as powdery mildew, rust, sheath blight, etc. [0003] Difenoconazole is a systemic broad-spectrum fungi...
