Embodiment 1

[0030] Example 1: 20% benzothiastrobin·benzamid wettable powder (1:1)

[0031] Benzostrobin (active ingredient) 10%, benzamid (active ingredient) 10%, sodium lignosulfonate (dispersant) 4%, sodium lauryl sulfate (wetting agent) 4%, attapulgite (Filler) is added to 100%; each component is mixed evenly, pulverized and mixed by a pulverizer to obtain 20% benzothiastrobin·benzamid wettable powder.

Embodiment 2

[0032] Example 2: 26% benzothiastrobin·benzamid wettable powder (25:1)

[0033] Benzostrobin (active ingredient) 25%, benzamid (active ingredient) 1%, formaldehyde condensate of sodium methylnaphthalenesulfonate (dispersant) 5%, calcium dodecylbenzenesulfonate (wetting agent) ) 4.5%, and diatomaceous earth (filler) to make up to 100%; each component is mixed evenly, pulverized and mixed by a pulverizer to obtain 26% benzothiastrobin·benzamid wettable powder.

Embodiment 3

[0034] Example 3: 32% Penthiastrobin · Benhexamid Suspension Concentrate (15:1)

[0035] Benzostrobin (active ingredient) 30%, benzamid (active ingredient) 2%, nonylphenol polyoxyethylene ether (dispersant) 3.5%, sodium alkylnaphthalene sulfonate (dispersant) 2%, ten Calcium dialkylbenzenesulfonate (wetting agent) 5%, xanthan gum (thickener) 3%, propylene glycol (antifreeze) 2.5%, C8-10 fatty alcohol compound (defoamer) 0.5%, deionization Make up water (solvent) to 100%; first mix other additives, shear and mix them evenly in a shearing machine, then add benzothiastrobin and benzamid, and grind in a ball mill for 2 hours to obtain 32% benzothiastrobin·benzamid suspension concentrate.

Abstract

The present invention relates to a bactericidal composition containing benzothiostrobin and zoxamide, wherein the effective components comprise benzothiostrobin and zoxamide according to a weight ratio of 25-1:1-25. According to the present invention, the bactericidal composition formed by compounding benzothiostrobin and zoxamide is used for preventing and controlling the downy mildew of crops, wherein the prevention and control effect is significantly higher than the prevention and control effect of the single use of benzothiostrobin and zoxamide so as to save the prevention and control cost; and the bactericidal composition of the present invention has advantages of good sterilization effect, long effective duration, safety to crops, pesticide consumption reducing, reduction of the pesticide residue in agricultural products, environment pollution reducing, delaying of the generation of the drug resistance of pathogenic bacteria, and pesticide service life prolonging.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to a bactericidal composition containing benzstrobin and benzamid. Background technique [0002] Benzamide, known as zoxamide in foreign language, is a highly effective protective fungicide, mainly used to control oomycete diseases such as potato and tomato late blight, cucumber downy mildew and grape downy mildew. At present, benzamid is widely used to control cucumber downy mildew. [0003] Benzothiostrobin, English name benzothiostrobin, (test code Y5247), is an innovative fungicide candidate species with independent intellectual property rights, which can be widely used to prevent and control powdery mildew, downy mildew, gray mold and brown spot of vegetables and melons and fruits disease, scab, corn leaf spot, rice false smut, citrus ground rot, rape sclerotinia, etc. Benthiastrobin and azoxystrobin and other methoxyacrylate fungicides have the same mechanism o...
