Problems solved by technology

These agents have produced varying degrees of resistance due to long-term use, and the control effect has decreased.
In addition, when the dosage of triazoles is large, the growth of crops can be inhibited, and it is easy to cause phytotoxicity.

Embodiment 1

[0032] Take 31% benzovinfluconazole prothioconazole triazole fungicide water emulsion (EW) as an example, but in actual application it is not limited to 31%, it can be rationally optimized according to the preferred ratio in the claims, Specific examples:

[0033] Benzene fluconazole 10%, prothioconazole 20%, triazole fungicide 1%, fatty acid methyl ester 10%, isopropanol 4%, alkyl aryl polyoxyethylene polyoxypropylene ether 2.5%, Castor oil resin polyoxyethylene ether 1%, xanthan gum 0.10%, ethylene glycol 1.5%, sodium benzoate 0.20%, polyether 0.8%, make up with water, fully dissolve the active ingredients first, add surfactant, stabilizer Wait for the rest of the additives and water, stir well, and then shear at high speed until the particle size D90=5μm, it is a uniform water-soluble emulsion with milky white microstrip blue fluorescence.

Embodiment 2

[0035] When the composition is made into a suspending agent, it contains the following component contents:

[0036] Take 20.75% benzovinfluconazole prothioconazole methoxyacrylate suspending agent (SC) as an example, but in actual application it is not limited to 25%, it can be rationally optimized according to the preferred ratio in the claims , a specific example:

[0037] Benzene fluconazole 5%, prothioconazole 15%, methoxyacrylate 0.75%, phenylphenol polyoxyethyl ether phosphate 2%, polycarboxylate 1%, polycarboxylate 1.5%, 0.15% xanthan gum, 2.5% glycerin, 0.30% sodium propionate, 0.8% 20% polydimethylsiloxane emulsion, supplemented with water, put the above materials into the mixing reactor in turn according to the formula ratio and requirements and stir evenly , high-speed grinding by a sand mill to a particle size of D90 = 5μm, and then homogenized and blended into a uniform off-white suspension.

Embodiment 3

[0039] When the composition is made into water-dispersible granules, it contains the following components:

[0040] Take 30.75% benzovinfluconazole Prothioconazole Methoxyacrylate water dispersible granule (WG) as an example, 15% of benzovinfluconazole original drug, 15% of prothioconazole original drug, formazan Oxyacrylate 0.75%, naphthalenesulfonic acid condensate sodium salt 8%, sodium lauryl sulfate 5%, ammonium sulfate 15%, white carbon black 2%, light calcium carbonate 5% / water-washed kaolin make up. First mix the original drug and other additives evenly, air powder, add water and knead, finally granulate and dry.

Abstract

The invention relates to a bactericidal composition. The bactericidal composition is characterized in that the effective constituent of the bactericidal composition is a mixed component consisting of a component I, a component II and a component III, wherein the component I is benzovindiflupyr; the component II is prothioconazole; the component III is selected from triazole fungicide or strobilurin, and the mass ratio of the component I, the component II and the component III in the mixed component is 100:1:1-1:1:100. The complex synergism of the three effective constituents is remarkable, and the bactericidal composition has excellent preventing and treating effect on various diseases of crops such as rice and vegetables. By the bactericidal composition, the disease preventing and treating effect is improved, meanwhile, a bactericidal spectrum is expanded, the use amount of pesticide is further reduced, residual quantity of the pesticide on the crops is reduced, pollution to the environment is also reduced, and pesticide resistance is delayed.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a bactericidal composition, in particular to a fungicide containing benzovinfluconazole, prothioconazole and triazoles or containing benzovinfluconazole and prothioconazole A fungicidal composition with a methoxyacrylate component and its application. Background technique [0002] Benzovindiflupyr (English name benzovindiflupyr) is a pyrazole amide fungicide developed by Syngenta and is a succinate dehydrogenase inhibitor. The fungicide is mainly used for cereal crops, and has excellent control effects on major diseases of various crops such as wheat, corn and special crops, and can well control wheat leaf blight, peanut black spot, wheat take-all and wheat base Rot, especially against wheat powdery mildew, small spot of corn and botrytis cinerea, and has excellent control effect against Asian soybean rust. [0003] Prothioconazole (English name prothioconazole) is a new typ...
