Problems solved by technology

With the continuous use of methoxyacrylate fungicides in large quantities, more and more pathogenic bacteria have developed resistance to them, and the cost of use is high, so the large-scale promotion and use of methoxyacrylate fungicides is limited.

Embodiment 1

[0041] Example 1: 22% Dicloconazole Benthiastrobin Microcapsule Suspension

[0042] The following substances are all percentages by weight: dicloconazole 11%, benzathystrobin 11%, polytoluene-2,4-diisocyanate (capsule wall material) 10%, hydroxyethyl cellulose (capsule wall material) 5%, sec-butyl acetate (solvent) 10%, alkylphenol polyoxyethylene ether sulfosuccinate (emulsifier) ​​5%, sodium methylene bis-naphthalene sulfonate formaldehyde condensate (dispersant) 5%, Sodium benzoate (preservative) 0.5%, deionized water to make up to 100%. After the above-mentioned materials are mixed and stirred according to the proportion, and polymerized, a 22% dicloconazole·benzothiastrobin microcapsule suspension can be prepared.

Embodiment 2

[0043] Example 2: 30% dicloconazole dikestrobin microcapsule suspension

[0044] The following substances are all percentages by weight: dicloconazole 25%, dikestrobin 5%, polyacryl acetate (capsule wall material) 8%, hydroxyethyl cellulose (capsule wall material) 5%, sec-butyl acetate Ester (solvent) 10%, alkylphenol polyoxyethylene ether sulfosuccinate (emulsifier) ​​5%, alkylbenzenesulfonate amine salt (dispersant) 5%, sodium benzoate (preservative) 0.5%, remove Ionized water tops up to 100%. After the above-mentioned materials are mixed and stirred according to the proportion, and polymerized, a 30% dicloconazole dikesstrobin microcapsule suspension can be prepared.

Embodiment 3

[0045] Example 3: 20% Dicloconazole Fluoxastrobin Microcapsule Suspension

[0046] The following substances are all percentages by weight: dicloconazole 5%, fluoxastrobin 15%, polyacryl acetate (capsule wall material) 8%, ethylenediamine (capsule wall material) 10%, sec-butyl acetate ( solvent) 10%, ethoxylated castor oil (emulsifier) ​​5%, alkylbenzenesulfonate amine salt (dispersant) 5%, sodium benzoate (preservative) 0.5%, and deionized water to make up to 100%. After the above-mentioned materials are mixed and stirred in proportion and polymerized, a 20% dicloconazole-fluoxastrobin microcapsule suspension can be prepared.

Abstract

The invention discloses a sterilization composition containing dichloro famoxadone and a methoxy acrylate sterilizing agent. The methoxy acrylate sterilizing agent is one of benzothiostrobin, benzene kresoxim-methyl, fluoxastrobin, azoxystrobin, pyraclostrobin, trifloxystrobin or picoxystrobin, and a weight ratio of dichloro famoxadone to the methoxy acrylate sterilizing agent is 20:1-1:20. The sterilization composition can be used for preventing and controlling various diseases like late blight, powdery mildew, downy mildew, banded sclerotial blight, gray mold, brown spot and anthrax on crops. Compared with existing preparations containing dichloro famoxadone or the methoxy acrylate sterilizing agent, the sterilization composition is remarkable in synergistic effect, excellent in sterilization effect, wide in sterilization spectrum, long in acting duration and safe to the crops, pesticide consumption is reduced, pesticide residue on the crops is lowered, environment pollution is reduced, generation of pesticide resistance of pathogenic bacteria is delayed, and service life of pesticide is prolonged.

Description

Technical field [0001] The invention relates to a pesticide bactericidal composition and its application field. Specifically, it is a binary compound compounded with dicloconazole and methoxyacrylate fungicides as active ingredients. It is mainly used for the prevention and control of diseases on crops. . Background technique [0002] Dicloconazole is an oxazole sulfone fungicide with the chemical name: 2-methylsulfone-5-(2,4-dichlorophenyl)-1,3,4-oxadiazole. The molecular structure is shown in the following formula. It is a new type of low-toxicity and safe fungicide that has good control effect on potato late blight and other fungal diseases. Its practical application has the disadvantage of a narrow bactericidal spectrum, and it cannot solve the problem of mixed diseases on crops when used alone. [0003] [0004] Methoxyacrylic acid fungicides are newly developed fungicides in recent years. The active group of this type of fungicide is methoxyacrylic acid (ester / ami...
