example 1～8

[0045] Examples 1-8 Wettable powders

[0046] Mix pyrimidine nucleoside antibiotics, penconazole (flusilazole, tricyclazole, tricyclazole), dispersant, wetting agent, and filler in a mixing tank evenly, and then pulverize by a jet mill and then mix them evenly. Pyrimidine nucleoside antibiotics, penconazole (flusilazole, tricyclazole, tricyclazole) wettable powder products were prepared, as shown in Table 1 for details.

[0047] The components and parts by weight of Table 1 Examples 1-8

[0048]

[0049] The new preparations can be prepared by exchanging penconazole, flusilazole, tricyclazole and tricyclazole in the table.

example 9～16

[0050] Examples 9-16 Water Dispersible Granules

[0051] Pyrimidine nucleoside antibiotics, penconazole (flusilazole, tricyclazole, tricyclazole), dispersing agent, wetting agent, disintegrating agent, filler, etc. are air-milled together to obtain the desired particle size, and then the adhesive is added. Additives and other auxiliaries to obtain granulation materials. The material is quantitatively fed into the fluidized bed granulation dryer, and after granulation and drying, the pyrimidine nucleoside antibiotics penconazole (flusilazole, tricyclazole, tricyclazole) water dispersible granules can be prepared. product, see Table 2 for details.

[0055] The new preparations can be prepared by exchanging penconazole, flusilazole, tricyclazole and tricyclazole in the table.

example 17～24

[0056] Examples 17-24 Suspension agent

[0057] Pyrimidine nucleoside antibiotics, penconazole (flusilazole, tricyclazole, tricyclazole), dispersing agent, wetting agent, defoaming agent, thickening agent and antifreeze are mixed uniformly through high-speed shearing, and then added. The original drug is ball-milled in a ball mill for 2 to 3 hours, so that the particle size of the particles is all below 5 μm, and the remainder is made up with deionized water, and the pyrimidine nucleoside antibiotics penconazole (flusilazole, tricyclazole) can be prepared. , powder triazole) suspending agent product, see Table 3 specifically.

Abstract

The invention discloses a bacteriocidal composition containing pyrimidine nucleoside antibiotics and triazoles. The bacteriocidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from the pyrimidine nucleoside antibiotics; the active ingredient B is selected from any one of the following compounds: penconazole, flusilazole, tricyclazole and flutriafol; and the weight ratio of the active ingredient A to the active ingredient B is 1:70-70:1. The bacteriocidal composition can be used for preventing and treating rust diseases, powdery mildew, epidemic diseases, alternaria leaf spots, scabs, brown spots, black spots, wilt, banded sclerotial blight, leaf spot diseases, ring spots, downy mildew, anthracnose, false smut, rice blast, smut, leaf mold, brown rots, white rots and stalk break occurring on cereal crops, fruit trees, vegetables and ornamental plants. The bacteriocidal composition has the characteristics of wide bacteriocidal spectrum, small consumption, rainwash resistance and obvious synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a synergistic bactericidal composition containing pyrimidine nucleoside antibiotics and triazoles on crop diseases. technical background [0002] Pyrimidine nucleoside antibiotics (agricultural antibiotic 120) alias: agricultural antibiotic 120; antimycotic 120; 120 agricultural antibiotics. Pyrimidine nucleoside antibiotic is a kind of high-efficiency, broad-spectrum biological fungicide with dual effects of preventive protection and systemic treatment; the protective components of this product can form a dense polymer protective film on the surface of plants and fruits. All kinds of pathogenic bacteria have strong inhibitory and hindering effects; the therapeutic ingredients can reach the inside of the fruit through the branches and trunks, directly hinder the synthesis of pathogenic proteins, and cause their death. This product is densely protected and has...
