specific Embodiment approach

[0068] 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 that may be included within the scope of the claims.

[0069] The inventor mixes fenoxastrobin with tribenazole, imazalil, cyanazazole or metconazole, and uses cucumber powdery mildew, cucumber downy mildew, tomato early blight, capsicum anthracnose, and wheat head blight as examples. Subjects were subjected to a joint toxicity test, and the specific test conditions and results are as follows:

[0070] The pot seedling assay method was used for the joint toxicity test of the pesticides to cucumber powdery mildew.

[0071] Cucumber powdery mildew bacteria cultivation and preparation of inoculation materials: Cucumber powdery mildew leaves were collected from cucumber cultivation sites that had n...

Embodiment 1

[0135] Example 1: 5% oxastrostrobin·carbenazole microemulsion (ME)

[0136] Weigh 2.5g of the original drug of enoxastrobin, 2.5g of the original drug of carbazole, 5g of N-methylpyrrolidone, 10g of isopropanol, 4.5g of Nongru 600#, 5.5g 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

[0137] Example 2: 81% oxastrobin·carbenazole wettable powder (WP)

[0138] Weigh 1g of the original drug of fenoxastrobin, 80g of the original drug of carbazole, 1g of sodium dodecylbenzenesulfonate, 10g of sodium lignosulfonate, and make up to 100g with light calcium carbonate. The above raw materials are mixed, pulverized and mixed by a jet mill to obtain a wettable powder.

Abstract

The invention specifically relates to a pesticide composition and application thereof, belonging to the technical field of pesticides. The composition comprises active components, a filling material and an adjuvant, wherein an active component A is fenaminstrobin and an active component B is one or more selected from the group consisting of fenbuconazole, imazalil, cyazofamid and metconazole. Thecomposition in the invention has good prevention and treatment effect on a plurality of plant diseases caused by fungi like ascomycetes, basidiomycetes, imperfect fungi and oomycetes and can effectively prevent and control the incurrence and harm of plant diseases like the downy mildew, powdery mildew, anthracnose and scab of cucumber, the late blight, leaf mold, early blight and gray mold of tomatoes, and the powdery mildew, anthracnose, gummy stem blight and blight of watermelons and melons. The composition has a wide bactericidal spectrum and effective synergistic effect, is reduced in dosage and application cost, and delays the occurrence and development of resistance of pathogens to a single pesticide, thus effectively preventing the occurrence and development of resistance of pathogens.

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 active ingredient A erythrostrobin and active ingredient B (one or more of fenoxenazole, imazalil, cyaconazole, and metconazole) compositions and their applications. Background technique [0002] A variety of plant diseases caused by Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes cause varying degrees of losses to crop planting and production every year. Plant diseases caused by Ascomycetes, Basidiomycetes, Oomycetes and Deuteromycetes fungi include cucumber downy mildew, powdery mildew, anthracnose, scab, tomato late blight, leaf mold, early blight, gray mold, western Melon powdery mildew, anthracnose, vine blight, fusarium wilt, grape downy mildew, anthracnose, powdery mildew, black pox, white rot, gray mold, apple leaf spot, brown spot, scab, Ring spot, anthracnose, melon and pepper a...
