NOVELTY - Manufacturing Trichoderma agent involves crushing carrier and controlling fineness to 40-60 mesh, regulating humidity to 8-12%, adding UV protective agent and mixing up for use; drying solid substrate fully-loaded with Trichoderma meristematic spores in normal temperature and crushing into powder, dissolving powder into water 8 times by weight, spraying them to carrier and protective agent, mixing uniformly and drying until relative humidity is 10-15%, packing tight, storing and forming agents, where powder, protective agent and carrier are in mass ratio of 10:1-5:85-90.    USE - For manufacturing Trichoderma agents (claimed) used to prevent diseases of multiple crops; and for preventing and treating diseases caused by soil-borne plant pathogenic bacteria such as rhizoctonia and bacteria of genera Fusarium, Pythium, and Phytophthora.    ADVANTAGE - The Trichoderma agent manufacturing method has short manufacturing cycle, simple working procedure, allows large spore production, uses wide raw material sources and has lows cost. The method has short production period, is simple process, and forms large spores. The Trichoderma microbial inoculum prepared by the method has long storage period (preferably storage period of 1 year), and has improved disease preventing effect. The method improves rate of emergence by 45%. The agent has survival ratio of 50%, has improved protecting effect, reduces disease index by 60%, is harmless to human, livestock and ecological environment, forms no residue, no drug resistance, uses wide source of raw materials, has production cost lower than chemical carbendazim pesticide, can efficiently change the waste into valuable, and has good economic benefit and social benefit. The method has high efficiency, high safety, and provides agent with various mechanisms of action and good environment compatibility. The agent is good for chemical industry upgrading; is effective at small dosage, has low toxicity and high efficiency, and is easy to decompose and so on. The agent reduces the usage amount of farm chemical, reduces drug resistance, reduces pollution and is good for protecting environment, and has positive effect for promoting ecological environment.    DETAILED DESCRIPTION - A method of manufacturing Trichoderma agents involves crushing the carrier and controlling the fineness to 40 to 60 meshes, regulating the humidity to 8 to 12%, adding ultraviolet protective agent to the carrier and mixing up for use; drying the solid substrates fully-loaded with Trichoderma meristematic spores in normal temperature and crushing into Trichoderma meristematic spore powder, dissolving the spore powder into water 8 times by weight, uniformly spraying them to the carrier and ultraviolet protective agent, mixing uniformly and drying until the relative humidity is 10 to 15%, packing tight, storing and obtaining Trichoderma agents, where Trichoderma meristematic spore powder, ultraviolet protective agent and carrier are at the mass ratio of 10:1-5:85-90. The carrier is vermiculite. The ultraviolet protective agent is humic acid.
