Problems solved by technology

If we do not pay attention to the prevention work in the early stage and start to use the medicine when the disease occurs, it is very likely that the occurrence of soil-borne diseases cannot be well controlled, and even cause crop production reduction and failure
[0003] Although there are currently fertilizers or planting methods for soil-borne diseases, the existing products or planting methods cannot be truly green and environmentally friendly, and the prevention effect is not good

preparation example Construction

[0038] A method for preparing a fungicidal composition for preventing soil-borne diseases, comprising the following steps:

[0039] Weighing step: weighing copper hydroxide, sulfur, quicklime and humic acid of formula quantity;

[0040] Mixing step: mixing the copper hydroxide, sulfur, quicklime and humic acid in the prescribed amount to obtain a semi-finished product;

[0041] Sieving and drying step: take the semi-finished product, dry it after sieving, and obtain the finished product;

[0042] Subpackage step: Subpackage the finished product.

[0043] As a further embodiment, in the mixing step, put copper hydroxide, sulfur, quicklime and humic acid in a formula amount into a mixing mixer, stir for 10-20 minutes, and control the temperature in the mixer to be 100-150 degrees Fahrenheit to obtain a semi-finished product .

[0044] As a further embodiment, in the sieving and drying step, the semi-finished product is taken, passed through a 100-mesh sieve, and dried after t...

Embodiment 1

[0048] A bactericidal composition for preventing soil-borne diseases, comprising the following components in parts by weight: 20 parts of 77% copper hydroxide; 15 parts of 80% sulfur; 55 parts of quicklime; 10 parts of fulvic acid. The bactericidal composition is prepared according to the following method:

[0049] Weighing step: weighing copper hydroxide, sulfur, quicklime and humic acid of formula quantity;

[0050]Mixing step: Put the copper hydroxide, sulfur, quicklime and humic acid in the formula amount into the mixing mixer, stir for 15 minutes, control the temperature in the mixer to 100-150 degrees Fahrenheit, and obtain the semi-finished product;

[0051] Sieving and drying steps: take the semi-finished product, pass it through a 100-mesh sieve, and then dry it after sieving to control the humidity of the product to 0-1.5% to obtain the finished product;

[0052] Subpackage step: Subpackage the finished product.

Embodiment 2

[0054] A bactericidal composition for preventing soil-borne diseases, comprising 70 parts of 77% copper hydroxide; 10 parts of 80% sulfur; 5 parts of quicklime; and 15 parts of humic acid.

[0055] Others are identical with specific embodiment 1.

Abstract

The invention discloses a bactericidal composition for preventing soil-borne diseases as well as a preparation method and application of the bactericidal composition. The bactericidal composition forpreventing soil-borne diseases comprises the following components in parts by weight: 10-90 parts of copper hydroxide; 0-30 parts of sulfur; 1-70 parts of quick lime; and 5-15 parts of humic acid, wherein the humic acid is humic acid and / or fulvic acid. The bactericidal composition is suitable for preventing and treating soil-borne diseases of continuous cropping vegetables and melon and fruit crops, has a good effect on fusarium wilt caused by fusarium and rhizoctonia solani caused by rhizoctonia solani, is efficient in sterilization, safe to the environment and human bodies and free of drugresistance to viruses, bacteria, fungi and the like, and is a simple and effective sterilization composition. Meanwhile, nutrient elements necessary for crop growth, such as a copper element and a sulfur element, can be supplemented while sterilization is performed, so that the use of chemical fertilizers is indirectly reduced, or the growth efficiency of crops in unit area is improved, and powerful help is provided for agricultural sustainable development.

Description

technical field [0001] The invention relates to the technical field of crop disease prevention and control, in particular to a fungicidal composition for preventing soil-borne diseases and a preparation method thereof. Background technique [0002] Soil-borne diseases refer to diseases caused by pathogens such as fungi, bacteria, nematodes and viruses that live in the soil with diseased residues and attack crops from roots or stems when conditions are suitable. Infection pathogens include fungi, bacteria, actinomycetes, and nematodes. To prevent and control soil-borne diseases, we must conscientiously implement the plant protection policy of "focusing on prevention and comprehensive prevention and control". If we do not pay attention to the prevention work in the early stage and only start to use the medicine when the disease occurs, it is very likely that the occurrence of soil-borne diseases cannot be well controlled, and even cause crop yield reduction and failure.
