The application discloses a microbial source bactericidal composition containing Leuconostoc mesenteroides WZ-44 and kasugamycin and application thereof. The bactericidal composition takes Leuconostoc mesenteroides WZ-44 fermentation liquor (or fermentation sterile filtrate) and kasugamycin as main effective components, wherein the mass ratio of the Leuconostoc mesenteroides WZ-44 fermentation liquor (or fermentation sterile filtrate) to the kasugamycin is 4999:1-99:1, and is further preferably 1499:1-499:1. The bactericidal composition shows a synergistic effect within the above-mentioned ratio range, overcomes and delays drug resistance of pathogenic bacteria, has a good prevention and control effect on pear fire blight, a long effective period and low application cost, is obviously superior to a single agent in the prevention and control effect, and greatly reduces the use amount of the kasugamycin.

The present application relates to a Paenibacillus polymyxa strain Y31, a microbial inoculum prepared therefrom and applications thereof. The strain Y31 can effectively inhibit the growth of Dothiorella gregaria, and field control tests show that the comprehensive prevention and control effect of the microbial inoculum prepared from the strain Y31 on the disease is as high as 72% or more in the early stage of the disease. Antagonistic experiments show that the strain Y31 also has good bacteriostatic effect on Dothiorella septospora and Dothiorella needle red rot fungus, and is suitable for being used as a broad-spectrum antibacterial agent in the biocontrol practice of pine fungal diseases. Meanwhile, the strain Y31 also has obvious inhibitory effect on bacterial diseases such as willow bacterial wilt fungus, pear fire blight fungus, walnut bacterial black spot fungus and kiwi fruit canker fungus, and can be used for the prevention and control of diseases such as willow wilt. In addition, the strain Y31 also has functions such as nitrogen fixation, phosphorus and potassium solubilization, and has certain salt and alkali tolerance, and can be used for promoting growth and disease resistance of plants in saline-alkali land.

This invention relates to the field of biological control, and in particular to a compound agent for controlling pear fire blight, its preparation method, and its application. This invention provides a compound agent with Bacillus vesicularis FX1 fermentation broth and kasugamycin aqueous solution as active ingredients, which can effectively control pear fire blight. The compound agent, by combining Bacillus vesicularis FX1 fermentation broth and kasugamycin aqueous solution, exhibits a synergistic effect. It leverages the high efficiency and rapid bactericidal advantage of kasugamycin while increasing the colonization of Bacillus vesicularis FX1 on the tree surface, making it the dominant foliar flora and constructing a stable and balanced micro-ecosystem. This can reduce the use of chemical pesticides by 60%, leveraging the synergistic and complementary effects of bacteria and pesticides to improve disease control, achieving the goal of safe, efficient, and sustainable control of the occurrence, spread, and diffusion of the disease.

This application discloses a strain of Bacillus belyceae DW4-5-2 for controlling pear fire blight and develops a highly efficient and stable microbial preparation fermentation method for it, clarifying its application in the control of pear fire blight. Compared with existing technologies, this application has the following advantages: the strain is highly novel; it has high antagonistic activity; it has excellent pot-plant control efficacy and a long-lasting effect; the fermentation process is thoroughly optimized; and it has broad application prospects. This strain and its optimized fermentation process provide core technical support for the development of highly efficient, stable, and environmentally friendly biological pesticides for pear fire blight, which is of great significance for ensuring the green, safe, and sustainable development of my country's pear and apple industries.

This utility model discloses a pear blight monitoring toolbox, including a base plate, a lower compartment fixedly connected to the top surface of the base plate, a middle compartment slidably disposed on the top surface of the lower compartment, and an upper compartment slidably disposed on the top surface of the middle compartment. The top surfaces of the lower, middle, and upper compartments are all open structures. Each of the lower, middle, and upper compartments contains a tool compartment, and multiple partitions are fixedly connected inside the tool compartment. Two first top sliding grooves are formed on both sides of the top surface of the lower compartment, and two first top sliding blocks are fixedly connected to both sides of the bottom surface of the middle compartment. The first top sliding blocks are horizontally slidably connected within the first top sliding grooves. Two second top sliding grooves are formed on both sides of the top surface of the middle compartment. The lower, middle, and upper compartments are slidably disposed, allowing them to be opened horizontally to display all tools for easy access and use, making it more practical.
