specific Embodiment approach 1

[0008] Specific embodiment one: the SF-1 water-soluble biological seed coating agent of prevention and treatment of corn head smut in this embodiment is the metabolite of bacterial strain SF-1 of 18~22 parts by volume, 2~5 parts of agricultural use per 100mL Enzyme bacteria (BYM), 0.02-0.04 parts of zinc sulfate, 0.01-0.02 parts of boric acid, 2.5 parts of polyoxyethylene, 2 parts of polyethylene glycol, 1-2 parts of water-soluble eosin, 4 parts of NaCl, 5 parts of ethylene glycol and The balance is composed of distilled water; the strain SF-1 is Streptomyces gardneri.

[0009] In this embodiment, water-soluble eosin is used as a warning color.

[0010] In this embodiment, the strain SF-1 is Streptomyces gardneri, which is stored in the General Microbiology Center of the China Microbiological Culture Collection Management Committee. Institute, the date of deposit is June 17, 2010, and the deposit number is CGMCC3928.

specific Embodiment approach 2

[0017] Specific embodiment two: what this embodiment is different from specific embodiment one is that the SF-1 water-soluble biological seed coating agent of prevention and treatment of corn head smut is every 100mL by the metabolite of 18 parts of bacterial strain SF-1 by volume fraction ratio , 2 parts of agricultural enzyme bacteria (BYM), 0.02 parts of zinc sulfate, 0.01 part of boric acid, 2.5 parts of polyoxyethylene, 2 parts of polyethylene glycol, 1 part of water-soluble eosin, 4 parts of NaCl, 5 parts of ethylene glycol and the balance of distilled water. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0018] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the SF-1 water-soluble biological seed coating agent for preventing and treating corn head smut is the metabolite of 22 parts of bacterial strain SF-1 by the ratio of parts by volume per 100mL , 5 parts of agricultural enzyme bacteria (BYM), 0.04 parts of zinc sulfate, 0.02 parts of boric acid, 2.5 parts of polyoxyethylene, 2 parts of polyethylene glycol, 2 parts of water-soluble eosin, 4 parts of NaCl, 5 parts of ethylene glycol and the balance of distilled water. Others are the same as in the first embodiment.

Abstract

The invention discloses an SF-1 water-soluble biological seed coating for preventing and curing maize head smut and relates to a biological seed coating for preventing and curing maize head smut. The invention solves the problems that the chemical preparation for preventing and curing the maize head smut has pollution to the environment and high residue and the germs easily become resistant to the chemicals. The SF-1 water-soluble biological seed coating for preventing and curing the maize head smut is composed of metabolic product of strains SF-1, farm lysozym, zinc sulfate, boric acid, polyoxyethylene, polyethylene glycol, water-soluble eosin, NaCl, ethylene glycol and the balance of distilled water. The biological seed coating of the invention can effectively prevent and cure the maizehead smut; the resistance ability of the crops is strengthened; the prevention and cure effect reaches 86.5% to 86.82%; the yield increasing rate of the maize reaches 13.69% to 14.28%; in addition, the invention is beneficial to the growth of the underground part of the maize plants, promotion of the root growth, promotion of the growth and development of the entire plants, no influence to the safety of the maize, no pollution to the environment, no residual and difficulty of generating resistance to the chemicals.

Description

technical field [0001] The invention relates to a biological seed coating agent for preventing and treating corn head smut. Background technique [0002] Maize head smut (Sporisorium reiianum (kuhn.) langdon & Fuiierton) is an important disease in spring-sowed maize regions in China, and it commonly occurs in Northeast, North, Northwest, Southwest and South China. The disease is a systemic invasive disease that invades during the germination stage of corn. Once the disease occurs, the ears will be destroyed first. The incidence rate is equal to the loss rate, causing great losses to corn production. At present, chemical agents (chemical components prepared as seed coating agents) are mainly used to prevent and treat corn smut disease, but there are problems such as environmental pollution, high residue, and easy resistance of pathogens to bacteria, which is contrary to the current green agriculture advocated. Therefore, It is imminent to choose suitable biocontrol agents to...
