The invention discloses wuyiencin spore powder and a production technology thereof. The production technology comprises liquid culture, solid culture, drying, crushing and separation so as to obtain the wuyiencin spore powder, wherein spore number of the wuyiencin spore powder is greater than or equal to 50.0*10<8>, the water content is less than or equal to 8%, the pH value is 4.0-7.0, and the resolution ratio of the effective components is less than or equal to 5%. In the invention, through the expansion culture of liquid phase before solid phase, the spore powder content of the obtained wuyiencin spore powder is greater than 50*10<8> / g, thus the stress resistance of the spores is strong, thereby being favorable for storage and transportation; the wuyiencin spore powder can be used in various modes by directly spraying powder or spraying after being prepared into a liquid preparation, thereby being convenient to use; and the wuyiencin spore powder is particularly suitable for preventing diseases of woods and fruit trees, and has an obvious prevention effect.
