Embodiment 1

[0025] Prothioconazole 5g, amino oligosaccharin 10g, cleaning agent LS (sodium p-methoxy fatty acid aminobenzene sulfonate) 2g, diffusing agent NNO (sodium methylene bis-naphthalene sulfonate, the same as in the following examples) 4g, 5g of white carbon black, and 100g of kaolin are added to the mixture and subjected to jet milling to obtain a wettable powder with an active ingredient weight percentage of 15%.

Embodiment 2

[0027] Add 3g of prothioconazole, 12g of amino oligosaccharin, 3g of sodium lauryl sulfate, 4g of diffusant NNO, 5g of white carbon black, and kaolin to 100g of the mixture and carry out jet milling to obtain an active ingredient weight percentage of 15%. wettable powder.

Embodiment 3

[0029] Add 2g of prothioconazole, 12g of amino oligosaccharin, 3g of sodium lauryl sulfate, 4g of diffusing agent, 5g of white carbon black, and kaolin to 100g of the mixture and carry out jet milling to obtain 14% by weight of active ingredients wettable powder.

Abstract

The invention belongs to the technical field of pesticides and relates to a bactericidal composition containing prothioconazole and a use thereof. The composition containing prothioconazole and amino-oligosaccharin is characterized in that a weight ratio of effective components such as prothioconazole to amino-oligosaccharin in the composition is 1-70: 1-50. The bactericidal composition has the advantages that (1) compared with a single agent, the composition has obvious synergism on resistant fungal diseases such as powdery mildew, sheath blight, wilt, leaf spot, rust disease, sclerotinia, net blotch, leaf blotch, gray mold, black spot, brown blotch, black shank and dustbrand, delays resistance to drugs, has a wide prevention and treatment spectrum, has high prevention and treatment effects and reduces production and use costs, (2) the composition reduces prevention and control labor and a use cost, (3) the composition can replace conventional pesticide and pesticide easy to produce resistance, and (4) the composition inhibits fungal resistance to drugs and has effects significantly higher than that of the single agent.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a bactericidal composition containing prothioconazole and the application of the composition. Background technique [0002] Prothioconazole, a triazolethione fungicide developed by Bayer Crop Science Company, is an ergosterol biosynthesis inhibitor. It has a long period and is currently mainly used in the field to control various diseases such as powdery mildew, fusarium wilt, leaf spot, sclerotinia, black shank, moire and other diseases on cereals, vegetables and other crops. [0003] [0004] Oligosaccharins, also known as chitosan oligosaccharides, are widely used in agricultural production and play an important role in crop disease resistance. They can induce the production of resistant substances in plants and enhance the ability of plants to resist external pathogenic bacteria. , At the same time, amino oligosaccharins can inhibit the growth of pathogenic mycelia, affe...
