Bactericidal composition containing fluazinam and prochloraz and application thereof

Abstract

The invention belongs to the field of pesticides and discloses a bactericidal composition containing fluazinam and prochloraz and application thereof. The composition is characterized by taking fluazinam and prochloraz as active ingredients, wherein the total mass percent of fluazinam and prochloraz is 5-70%; and the mass ratio of fluazinam to prochloraz is 30:1-1:20. The composition can be used for controlling rice blast, rice sheath blight, wheat leaf blight / rust, peanut leafspot / web blotch, tomato / potato late blight, cucumber gray mold / powdery mildew / anthracnose and citrus anthracnose. Thecomposition has wide range of application, low cost and good effect.

Description

technical field

[0001] The invention belongs to the field of pesticides and relates to a broad-spectrum bactericidal composition, in particular to a bactericidal composition containing fluazinam and prochloraz and an application thereof. Background technique

[0002] In recent years, plant diseases caused by fungi, bacteria, nematodes, viruses and malnutrition have become more and more serious, and the impact has also become greater.

[0003] Fluazinam is a 2,6-dinitroaniline compound, a protective fungicide, and an uncoupler for mitochondrial oxidative phosphorylation. Inhibits all stages of the infection process by inhibiting spore germination, mycelial breakthrough, growth and sporulation. Fluazinam has a broad bactericidal spectrum, and its effect is better than conventional protective fungicides. It has special effects on Alternaria, Botrytis, Phytophthora, Monopodella, Sclerotinia and Sclerotia, and Botrytis cinerea against benzimidazoles and dicarboximide fungicides...

Examples

Embodiment 1

[0015] Example 1: 50% fluazinam prochloraz suspension concentrate

[0016] Fluazinam 40kg

[0017] Prochloraz 10kg

[0018] Alkylphenol polyoxyethylene phosphate 6kg

[0019] Silicone milk defoamer 0.2kg

[0020] Xanthan gum 0.3kg

[0021] Water to make up to 100kg

[0022] After the above-mentioned metering components are mixed, they are stirred by a first-stage sand mill, and after a second-stage sand mill, they are prepared in a preparation kettle, and after the sampling inspection is qualified, the existing suspension preparation product is measured and packaged.

Embodiment 2

[0023] Example 2: 30% fluazinam prochloraz dry suspension

[0024] Fluazinam 10kg

[0025] Prochloraz 20kg

[0026] Sodium lignosulfonate 8kg

[0027] Sodium tripolyphosphate 3kg

[0028] Ammonium sulfate 12kg

[0029] Kaolin make up to 100kg

[0030] Mix and pulverize all the ingredients, add appropriate water, spray granulate and dry to obtain a dry suspension preparation product.

Embodiment 3

[0031] Example 3: 10% fluazinam prochloraz suspension seed coating

[0032] Fluazinam 4kg

[0033] Prochloraz 6kg

[0034] Phosphate emulsifier 5kg

[0035] Bentonite 2kg

[0036] Xanthan gum 0.3kg

[0037] Ethylene glycol 5kg

[0038] Polyvinyl alcohol blended modified film-forming agent 0.2kg

[0039] Pigment 0.2kg

[0040] Water to make up to 100kg

[0041] Fully mix the active ingredients, bentonite, emulsifier and part of the water above, then sand mill, then add the film forming agent, thickener, antifreeze and the rest of the water in turn into the preparation tank and mix thoroughly to obtain the suspended seed coating agent Formulation products.
