Embodiment 1

[0020] Embodiment 1: 10% hymexazol·50 billion spores / gram Bacillus subtilis wettable powder

[0021]Get 50 kilograms of Bacillus subtilis former powder (100 billion spores / gram), 10.2 kilograms of 98% hymexazol former medicine, 3 kilograms of alkylnaphthalene sulfonate condensation polymer sodium salt, 2 kilograms of sodium isopropyl naphthalene sulfonate, 5 kg of magnesium aluminum silicate, 29.8 kg of diatomaceous earth, all the raw materials are mixed evenly, pulverized by a pulverizer and sieved. Promptly make 100 kilograms of 10% hymexazol·50 billion spores / gram Bacillus subtilis wettable powder like this, and this product is sepia powder.

[0022] Detection method of hymexazol content: high performance liquid chromatography. The sample was dissolved and diluted with methanol, methanol: 0.1% acetic acid aqueous solution (80:20) was used as the mobile phase, and the TC-C18 (2) stainless steel column was used as the packing stainless steel column and a variable wavelength ...

Embodiment 2

[0044] Example 2: 5% Hymexazol · 20 billion spores / gram Bacillus subtilis SC

[0045] Get 20 kg of Bacillus subtilis powder (100 billion spores / gram), 1 kg of alkyl naphthalene sulfonate, 2 kg of phenylethylphenol polyoxyethylene polyoxypropylene ether, 0.1 kg of xanthan gum, magnesium aluminum silicate 1 kg, 60 kg of water, after stirring evenly, enter the colloid mill and sand mill for grinding. When the fineness of the material reaches 1-5 microns, the material is transferred to the reaction kettle. Add 5 kg of hymexazol to the reaction kettle and stir for 30 minutes until the hymexazol is completely dissolved, then add 0.5 kg of 37% hydrochloric acid solution and stir for 10 minutes, and finally add water to make up to 100 kg. Promptly obtain 5% hymexazol · 20 billion spores / gram Bacillus subtilis aqueous suspension.

[0046] The assay method of active ingredient content in this water suspension concentrate is identical with the assay method among the embodiment 1. Afte...

Embodiment 3

[0047] Example 3: 10% Hymexazol · 60 billion spores / gram Bacillus subtilis WDG

[0048] Get 60 kilograms of the former powder of Bacillus subtilis (100 billion spores / gram), 10.2 kilograms of the former medicine of 98% hymexazol, 4 kilograms of alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, 2 kilograms of alkylnaphthalene sulfonate kg, 2 kg of fatty alcohol polyoxyethylene ether, 3 kg of white carbon black, and 18 kg of kaolin were put into a mixer and fully mixed, and pulverized by a jet mill. In the kneader, 13 kg of water was uniformly added to the pulverized material for kneading, and then put into the granulator for extrusion granulation. Transfer the extruded wet granules to a fluidized bed for drying until the residual moisture content in the product is about 1%. Promptly make about 100 kilograms of 10% hymexazol·60 billion spores / gram Bacillus subtilis water-dispersible granule like this.

[0049] The assay method of the active ingredient content ...

Abstract

The invention relates to a compounded soil treating agent and application thereof and in particular relates to a bacillus subtillis and hymexazol compounded bactericide. The active ingredients consist of bacillus subtillis R31 and hymexazol and account for 5-90 percent by weight of the bactericide; a weight ratio of hymexazol original medicine to bacillus subtillis raw powder is (1-5):(1-15); the agent can be in the form of suspension concentrate, wettable powder or water dispersible granules. The compound preparation can simultaneously kill various fungi and bacterial pathogens in soil and effectively prevent and treat soil-borne diseases, does not have an adverse effect on soil probiotics (such as bacteria and actinomycetes), and is free of pollution; reasonable distribution of soil microbial communities can be realized after lots of bacillus subtillis is bred, and finally, a reasonable ecological structure in soil is realized. After being applied for a long time, the agent can achieve the effects of fundamentally treating the soil-borne diseases, improving the soil microbial environment, improving the soil fertility, promoting crop growth, enhancing the crop disease resistance and improving the crop yield and quality.

Description

technical field [0001] The invention relates to a compound soil treatment agent and its application, especially a compound fungicide of Bacillus subtilis and hymexazol, which can not only effectively prevent and control soil-borne diseases, but also kill various fungi and bacteria in the soil at the same time. Bacterial pathogenic bacteria; and it has little effect on beneficial bacteria such as bacteria and actinomycetes other than pathogenic bacteria in the soil, which can improve the ecological structure of the soil; it can also promote the growth of crops and improve the disease resistance of crops. technical background [0002] Relying on chemical fertilizers and chemical pesticides, agriculture has achieved great development in a very short period of time, the grain output has increased significantly, and the problem of people's food has been solved. However, the long-term and large-scale use of chemical fertilizers and chemical pesticides has also caused unprecedented...
