Problems solved by technology

[0004] Wheat rust, powdery mildew, and head blight are the main diseases in the middle and late stages of wheat production. A single use of a fungicide has limited killing effect on pests and diseases, and a single fungicide is likely to cause pathogenic microorganisms to develop drug resistance after a period of use. Reduced effectiveness in killing pests and diseases

Embodiment 1

[0021] The fungicide composition containing bixafen and kresastrobin of embodiment 1 suspension

[0022] According to Table 1, add water, emulsifier, dispersant, and antifreeze into the mixing tank and stir, mix evenly, then put bixafen and kyresastrobin into the mixing tank, stir evenly, and then through shearing, sanding Grinding, and then uniformly mixing with a thickener to prepare a series of suspension-type fungicide compositions containing bixafen and kyrestrobin, respectively numbered X-1 to X-7.

[0023] Wherein, A is the abbreviation of bixafen; B is the abbreviation of kysoxafen; A:B represents the weight ratio of bixafen and kysoxafen; (A+B)% represents bixafen and The percentage that the sum of the weights of kresastrobin accounts for in the total weight of the fungicide composition. The meanings of A and B in other embodiments are the same as above.

[0024] At the same time, control samples DX-1 to DX-4 were prepared according to the above method for use in su...

Embodiment 2

[0027] The fungicide composition containing bixafen and kresastrobin of embodiment 2 emulsifiable oil type

[0028] According to Table 2, put NN dimethylformamide and Nongru 1602 into the mixing kettle, stir evenly, then put bixafen and kyresastrobin into the mixing kettle and stir evenly, it becomes a uniform and transparent liquid, and prepares a A series of cream type fungicide compositions containing bixafen and kresastrobin, respectively numbered R-1 to R-7.

[0029] The specific formulation of the fungicide composition of different emulsifiable oil types of table 2

[0030]

Embodiment 3

[0031] The fungicide composition containing bixafen and kresastrobin of embodiment 3 water-dispersible granules

[0032] According to Table 3, mix bixafen, kresastrobin, and fillers uniformly, pulverize them through a jet mill, and then mix them with wetting agents, dispersants, disintegrants, and binders, and then mix them according to the total weight of the above mixtures. Add 10% water, mix evenly, and prepare a series of water-dispersible granule fungicide compositions containing bixafen and kysoxafen after extrusion granulation, drying, sieving, etc., respectively numbered S-1 ~S-7.

[0033] The specific formulation of the fungicide composition of different water dispersible granule dosage forms of table 3

[0034]

[0035] Note: Water for granulation is added separately according to 10% of the total weight of the formula in Table 3, and it is dried and removed after granulation, so it is not listed in Table 3.

Abstract

The invention belongs to the technical field of pesticides, in particular to a fungicide composition containing bixafen and kresastrobin. The active ingredients of the fungicide composition are bixafen and kysoxazim, and the weight ratio of bixafen and kysoxazim is (30:1)-(1:30). The invention adopts the mixed use of fungicides bixafen and kresastrobin with different action mechanisms, which has obvious synergistic effect on wheat powdery mildew, wheat rust and wheat head blight, and effectively controls the resistance of pathogenic microorganisms ; Field tests showed that when the ratio of bixafen and kresastrobin was 10:1, after 7 days of use, the control effect on wheat rust was as high as 93.36%, and the control effect on wheat powdery mildew was as high as 94.04%. The control effect of wheat head blight was as high as 91.57%, which was significantly higher than that of bixafen single agent and kysoxafen single agent.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicide composition containing bixafen and kresastrobin and an application thereof. Background technique [0002] Bixafen (Bixafen), its chemical formula is C18H12Cl2F3N3O, its chemical name is N-(3′,4′-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1 -Methylpyrazole-4-carboxamide. Bixafen is a pyrazole fungicide, a new type of systemic fungicide with broad-spectrum, protective and therapeutic activities. Bixafen interferes with succinate dehydrogenase on complex II in the mitochondrial respiratory electron transport chain of pathogenic bacteria, inhibits mitochondrial function, prevents it from producing energy, inhibits the growth of pathogenic bacteria, and eventually leads to its death. Bixafen is a systemic fungicide with a broad spectrum of fungicides and is specially used for foliar sprays. Tests have proved that bixafen has excellent control effe...
