Embodiment approach 1

[0019] The bacillus amyloliquefaciens of LB liquid culture is made into 2.3 x 10 by the method of CN102870816A 9 cfu / g microcapsules.

Embodiment approach 2

[0021] Pseudomonas fluorescens cultured by liquid fermentation was adsorbed by soluble starch and added to 20% shellac solution, stirred evenly, and spray-dried to make 3.2 x 10 9 cfu / g paraffin-embedded Pseudomonas fluorescens slow-release bacterial agent.

Embodiment approach 3

[0023] The Bacillus brevis cultivated by liquid fermentation was adsorbed by soluble starch and added to 20% shellac solution, stirred evenly, and spray-dried to make 1.1 x 10 9 cfu / g wax-film-embedded Bacillus brevis slow-release agent.

Abstract

The invention belongs to the technical field of biology, and relates to a microbial combined agent for preventing and treating plant diseases and insect pests and promoting plant growth. The microbialcombined preparation is a combined preparation prepared from a quick dissolving microcapsule microbial agent and a bactericidal or insecticidal microorganism slow-release microbial agent according toa ratio of (1-5):(1-9) and used for regulating the growth and development of plants and preventing and treating plant diseases and insect pests, wherein the quick dissolving microcapsule microbial agent is prepared from bacillus amyloliquefaciens, and the bactericidal or insecticidal microorganism slow-release microbial agent is embedded by using a wax film material.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a microbial agent for preventing and controlling plant diseases and insect pests and promoting plant growth. Background technique [0002] Chemical pesticides play an important role in controlling agricultural pests, protecting agricultural production safety, and reducing labor intensity. With the development of the chemical industry and the expansion of the use of pesticides and fertilizers, the number and variety of chemical pesticides are increasing. Now the world's total output of chemical pesticides (in terms of active ingredients) exceeds 3 million tons. Due to the long-term and large-scale application of chemical pesticides and chemical fertilizers, serious environmental pollution and increasing resistance of diseases and insect pests have been brought about. Many countries have invested a lot of money in the research and development of new formulations that can replace or ...
