The invention discloses a
wettable powder of high sporopollen of
trichoderma and a preparation method thereof. The
wettable powder comprises the following materials with
mass percentages of: 5 to 6 percent of high sporopollen of
trichoderma, 1 to 2 percent of
fenaminosulf, 85 to 90 percent of diatomite and
bentonite, 2 to 3 percent of
sodium lignosulphonate, 0.5 to 1.0 percent of
active carbon, 0.1 to 0.5 percent of
citric acid and 1 to 2 percent of
sodium carboxymethyl cellulose, wherein the classified name of the biocontrol strain adopted by the high sporopollen of
trichoderma is TV-1 (trichoderna viride) and the preserving number is CGMCC No.2848. All the materials are mixed evenly, pre-crushed, then crushed by air flow, and sieved by a standard
sieve with the meshes of 325; and by quality inspection, the qualified
wettable powder of high sporopollen of trichoderma meets the following conditions that the content of the trichodrema
spore is more than 0.5 billion / g, active
spore rate is more than 80 percent, wettability is less than two minutes, suspension percentage is more than 70 percent,
fineness (sieved by the standard
sieve with the meshes of 325) is more than 99 percent, the
water content is less than 2 percent, pH is 5 to 6 and the like.
