Embodiment 1

[0029] S1, mix 0.5kg of Bacillus firmus parent drug, 3kg of thiamine thiocyanate, 2kg of wetting agent, 2kg of dispersing aid and 88kg of carrier, and pulverize through a jet mill to make the mixture fineness reach 400 mesh;

[0030] S2, then add 1.5kg of sodium ethylenediaminetetramethylene phosphonate and 2kg of binder to mix evenly, extrude and granulate by an extrusion granulator, and the particle size is D 90 =420 μm to obtain Bacillus firmus granules.

Embodiment 2

[0032] S1, mix 0.5kg of Bacillus firmus parent drug, 4kg of thiamine thiocyanate, 3.5kg of wetting agent, 3.5kg of dispersing aid and 183kg of carrier, and pulverize through a jet mill to make the mixture fineness reach 400 mesh;

[0033] S2, then add 1.5kg of sodium ethylenediaminetetramethylene phosphonate and 3.5kg of adhesive to mix evenly, and extrude and granulate through an extrusion granulator, with a particle size of D 90 =420 μm to obtain Bacillus firmus granules.

Embodiment 3

[0035] S1, mix 0.5kg of Bacillus firmus parent drug, 5kg of thiamine thiocyanate, 3.5kg of wetting agent, 3.5kg of dispersing aid and 183kg of carrier, and pulverize through a jet mill to make the mixture fineness reach 400 meshes;

[0036] S2, then add 1.5kg of sodium ethylenediaminetetramethylene phosphonate and 3.5kg of adhesive to mix evenly, and extrude and granulate through an extrusion granulator, with a particle size of D 90 =420 μm to obtain Bacillus firmus granules.

Abstract

The invention relates to the field of granules, and particularly discloses a bacillus firmus granule as well as a preparation method and application thereof. The bacillus firmus granule is prepared from the following raw materials in parts by weight: 0.5 to 1.5 parts of bacillus firmus mother powder, 5.5 to 7.5 parts of a promoting component, 88 to 276 parts of a carrier, 2 to 5 parts of a wetting agent, 2 to 5 parts of a dispersing aid and 2 to 5 parts of an adhesive, the preparation method comprises the following steps: uniformly mixing the bacillus firmus concentrate, the promoting component, the wetting agent, the dispersing aid and the carrier, crushing, adding the binder, and finally extruding and granulating to obtain the bacillus firmus granule. The bacillus firmus granule can be used for preventing and treating tomato and tobacco root-knot nematode, and has the advantage of improving the prevention and treatment effect of the bacillus firmus granule on the root-knot nematode.

Description

technical field [0001] The present application relates to the field of granules, and more particularly, to a Bacillus firmus granule and its preparation method and use. Background technique [0002] Granules are a solid dosage form obtained by mixing and granulating the original drug with auxiliary agents such as carriers, adhesives, dispersants, wetting agents, and stabilizers. Its performance requirements mainly include fineness, uniformity, storage stability, hardness and disintegration. [0003] Bacillus firmus is a new type of microbial bio-pesticides. After furrow application or root irrigation, its live spores reproduce in the root soil by using the nutrients and water from the root of the crop, and quickly occupy the soil around the rhizosphere of the entire crop to achieve effective inhibition and killing. The role of root-knot nematode eggs and larvae. [0004] In view of the above-mentioned related technologies, the inventors believe that the growth of Bacillus ...
