The invention belongs to plant disease biocontrol technical field, and relates to separation identification on bacteria for biocontrol of rice sheath blight, microbial inoculum containing the bacteria or a fermentation product thereof, and control on rice sheath blight. In the invention, the bio-control bacteria-a bacillus subtilis WJ-1 bacterial strain for controlling rice sheath blight is obtained by separating and screening and then preserved in China Center for Type Culture Collection, wherein, the preservation number is CCTCC No: M2010069. The invention further discloses a preparation method of the biocontrol microbial inoculum and an application of three bacillus subtilis WJ-1 microbial inoculum for controlling rice sheath blight. The biocontrol microbial inoculum of the invention has good biocontrol effect on plant fungal diseases such as rice sheath blight and the like.

The invention discloses a microbial inoculum for preventing and curing fungal diseases of plants; the active ingredients contain Trichoderma longibrachiatum and Trichoderma citrinoviride. The microbial inoculum of the invention is used to carry out control efficiency experiments and the results show that the control efficiency of liquid microbial inoculum to cucumber blight is up to 54.8% and thecontrol efficiency to green pepper phytophthora disease is up to 67.9%; the control efficiency of solid microbial inoculum to cucumber blight is up to 45.12% and the yield of cucumber is increased by11.06% so that the effect for preventing diseases and increasing yield is obvious; the control efficiency of solid microbial inoculum to green pepper phytophthora disease is up to 61.90% and the average plant height of the green pepper in experimental group is increased by 8.92% compared with that of the green pepper in control group and the yield of green pepper is increased by 37.19% so that the microbial inoculum of the invention is shown to have obvious effect for preventing increases, promoting the growth and increasing the yield.

The invention discloses the use of lansiumamide B or its salt as a fungicide. The compound is an amide alkaloid isolated from the wampee fruit stone, which has broad-spectrum bactericidal activity against various plant fungal diseases, and can be used alone or in combination with other agents for the prevention and control of various plant fungal diseases, especially for rice Sheath blight, rapeseed sclerotinia, and strawberry botrytis have better control effects. At the same time, the compound can also be used for seed treatment, medicinal fertilizer, and preservation of fruits, vegetables and fish.

A process of preserving tissue from one or more plant, fungus or algae species is provided. The process comprises treating such tissue by subsequent steps of (i) incubation with a weak acid solution; (ii) removal of excess acid; (iii) incubation with an aqueous sugar alcohol solution; (iv) removal of excess sugar alcohol; and (v) drying. Also provided is a textile material having a sheet like structure, and characterized in having an average thickness of about 0.2-5 mm and comprising about 2% to about 20% sugar alcohol.

This invention discloses the application of Streptomyces lydicus A02 CGMCC No.1654. After fermentation, the strain can produce active metabolite having strong antiseptic effects. The metabolite can be used for manufacturing biological agents for resisting plant fungi.

The invention relates to a liquid culturing method for establishing a DSE and corn symbiotic system and belongs to the fields of microbiology, plant nutriology and ecology. The liquid culturing method comprises the steps that aseptic seedlings are cultured through corn B73 seeds with the surfaces disinfected, DSE mycelia are cultured through a PDA culture medium, the corn aseptic seedlings and the DSE mycelia are cultured in an aseptic liquid culture medium together, and a plant-fungi symbiotic system without interference of infectious microbes is established. The liquid culturing method mainly comprises the steps of culturing the core aseptic seedlings, preparing a DSE inoculation agent, establishing DSE and core symbiote and detecting the symbiotic culturing system. The liquid culturing method has the advantages that the DSE and corn aseptic co-culturing liquid system is established, the method is stable and efficient, matrix ingredients are definite and uniform, an ideal model is provided for the further research of the infection mechanism of the DSE and the symbiosis mechanism of the DSE and plants, and meanwhile a method reference is provided for the research of other fungi and symbiotic plants.

Systems and methods of generating water for growing or vitally supporting plants, fungi, and / or aquatic animals are provided herein. The systems include a water generating unit that utilizes process fluid produced by plant transpiration or fungus respiration to generate water. Nutrients may be added to the water through hydroponic and aquaponic systems, then provided back to the plants in a closed loop. The systems may be monitored, optimized, and controlled remotely.

The invention discloses streptomyces hygroscopicus capable of producing salicylic acid and rapamycin and application of the streptomyces hygroscopicus to prevention and control of plant oomycetes andfungal diseases. The invention also discloses the streptomyces hygroscopicus capable of producing the salicylic acid and the rapamycin, which has the preservation number of CGMCC (China General Microbiological Culture Collection Center) No. 15518, and the application of the streptomyces hygroscopicus to the prevention and control of the plant oomycetes and fungal diseases. The invention identifiesa biocontrol bacterium aiming at the plant oomycetes and fungal diseases, especially phytophthora infestans and fusarium oxysporum; the bacterium can be used for remarkably inhibiting spore germination and mycelium growth of the phytophthora infestans; an effective method is provided for biologically preventing and controlling the plant oomycetes and fungal diseases, especially the phytophthora infestans and fusarium wilt. The method disclosed by the invention can be used for effectively preventing and controlling the phytophthora infestans, the fusarium wilt and other plant diseases and reducing the economic loss; the method has important meaning of reducing the utilization of pesticide and alleviating environment pollution, and also has significant application value of keeping the balance and sustainable development of an ecological system.
