Problems solved by technology

[0005] But using compound A of formula I alone or methoxyacrylate fungicides will cause narrow bactericidal spectrum, easily produce resistance, and use cost is high, which is very unfavorable for the needs of large-scale broad-spectrum bactericidal in agriculture, so it is urgent to develop New products to solve this technical problem
[0006] And so far, there is no literature disclosing compound A mixed with methoxyacrylate fungicides, and the resulting composition is used to prevent and treat agricultural diseases; thereby delaying the development of drug resistance of pathogenic bacteria and reducing farmers' drug costs

specific Embodiment approach

[0126] The following examples are only to further illustrate the present invention, but are not intended to limit the present invention to these specific embodiments. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

Embodiment 1

[0129] Embodiment 1: 4% enoxastrobin·compound A' microemulsion (ME)

[0130] Weigh 2g of the original drug of oxastrobin, 2g of the original drug of compound A', 5g of N-methylpyrrolidone, 10g of isopropanol, 4g of Nongru 600#, 6g of Nongru 1601#, and add water to make up to 100g. Add the original medicine, solvent and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain a Good microemulsion.

Embodiment 2

[0131] Embodiment 2: 66% erythrostrobin Compound A' water dispersible granule (WG)

[0132] Weigh 6g of the original drug of fenoxastrobin, 60g of the original drug of compound A', the sodium salt of 5g of alkylnaphthalenesulfonic acid condensation polymer, 14g of ammonium sulfate, 2g of alkylnaphthalenesulfonate and anionic wetting agent mixture, 0.4g of benzene Sodium formate and 12.6g corn starch. Mix evenly, after jet crushing, granulate in a granulator, then dry and sieve to obtain granular products.

Abstract

The invention belongs to the field of pesticides, and particularly relates to a bactericidal composition and an application thereof. The composition consists of active components, a filler and an auxiliary agent, wherein the active components are a compound A and a methoxyacrylate bactericide B. The composition is mainly used for preventing and curing rice blast of paddies. The composition has many action mechanisms and sites and can effectively delay the occurrence and development of drug resistance of pathogenic bacteria. The preparation technology is simple, the cost is low, and the economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of pesticides. It relates to a bactericidal composition and its application, in particular to a composition containing a compound A of formula (I) and a methoxyacrylate bactericide B and its application. Background technique [0002] Methoxyacrylate fungicides are an important class of agricultural fungicides. This type of fungicide is a new type of fungicide developed based on the natural antibiotic stobiluronA as the lead compound. It is an energy generation inhibitor and a new type of agricultural fungicide with great development potential in the field of pesticides. The common structural unit of methoxyacrylate fungicides is the (E)-β-methoxyacrylate unit, which is linked to other parts of the molecule at the α position. Methoxyacrylate fungicides act on complex III (Cyt bc1 complex) in the respiratory electron transport chain in mitochondria, bind to the Qo site of Cytb in the complex, and block the transfer of...
