specific Embodiment approach 1

[0016] Specific embodiment 1: A biological seed coating agent for preventing and controlling soybean soil-borne diseases in this embodiment consists of a fermentation broth, a dispersant of 10g / L to 50g / L, a carrier of 9g / L to 29g / L, and a 9g / L ~19g / L film-forming agent; wherein the fermentation liquid is composed of equal volumes of Brevibacillus lateralsporosa fermentation liquid and Bacillus subtilis fermentation liquid.

[0017] The beneficial effect of this implementation mode:

[0018] This embodiment provides a technology for preparing a biological seed coating agent using two kinds of bacillus, which is to use the pure fermentation liquid of the two bacillus to mix and then add an auxiliary agent to make a biological seed coating agent, which is used to prevent and control soybean root. For rot and soybean cyst nematode, the biological seed coating agent of this embodiment does not contain any highly toxic ingredients, is safe and environmentally friendly, and has a go...

specific Embodiment approach 2

[0019] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the dispersant is diatomaceous earth. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the carrier is sodium lignosulfonate. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a bio-seed coating agent for preventing and treating soil-borne diseases of soybeans and a preparation method of the bio-seed coating agent, and solves the problems of toxicity, unsafety and environmental pollution of pesticides for treating the soil-borne diseases in an existing method. The bio-seed coating agent is prepared from the following components: a fermenting solution, 10g / L-50g / L of a dispersing agent, 9g / L-29g / L of a carrier and 9g / L-19g / L of a film-forming agent, wherein the fermenting solution comprises a brevibacillus laterosporus fermenting solution and a bacillus subtilis fermenting solution which are the same in volume. The method comprises the following steps: 1, preparing the brevibacillus laterosporus fermenting solution; 2, preparing the bacillus subtilis fermenting solution; 3, adding the dispersing agent, the carrier and the film-forming agent, and uniformly mixing. The bio-seed coating agent does not contain any high-toxicity ingredients, is safe and environmentally friendly, and is used for preventing and treating soybean root rot and soybean cyst nematode. The method is used for preparing the bio-seed coating agent.

Description

technical field [0001] The invention relates to a biological seed coating agent and a preparation method thereof. Background technique [0002] Soybean root rot and soybean cyst nematode occur in all soybean producing areas in my country, especially in the three eastern provinces. They have the characteristics of serious damage and difficult control. They are usually the targets of highly toxic and highly toxic pesticides. However, as people With the improvement of safety and environmental awareness, the application of highly toxic and highly toxic pesticides in agriculture has been greatly restricted. At present, there is an urgent need for high-efficiency and low-toxicity biological pesticides to solve the hazards of soil-borne diseases. Seed coatings are often the main dosage form for the control of soil-borne diseases. There is no report on the compounding of Brevibacillus lateralosporus and Bacillus subtilis into biological seed coating agent at present. Contents of ...
