Microbial agent for preventing both root knot nematode disease and clubroot and preparation method thereof

Abstract

The invention discloses a microbial agent capable of preventing both root knot nematode disease and clubroot and a preparation method of the microbial agent, and relates to the technical field of fertilizers. The technical problems that in the prior art, field symptoms of the root-knot nematode disease and the clubroot disease are similar, rapid distinguishing and accurate medicament selection are difficult, and the root-knot nematode disease and the clubroot disease easily occur at the same time and are difficult to prevent and control in time are solved. The preparation method of the microbial agent for preventing both the root knot nematode disease and the clubroot disease comprises the following steps: preparing bacillus methylotrophicus powder and bacillus subtilis powder; preparing paecilomyces lilacinus powder; and compounding the prepared bacillus methylotrophicus powder, paecilomyces lilacinus powder and bacillus subtilis powder in proportion, and uniformly mixing to obtain the microbial agent capable of preventing both the root knot nematode disease and the clubroot disease. The prepared microbial agent for simultaneously preventing the root knot nematode disease and the clubroot disease can be used for uniformly preventing and controlling the two diseases, and the situation that the golden period of early prevention and control is delayed due to wrong medicament selection in agricultural production is avoided.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial agent for preventing root-knot nematode and clubroot and a preparation method thereof. Background technique [0002] Clubroot is caused by Plasmodium brassicae, a fungal disease that only occurs in cruciferous vegetables, such as Chinese cabbage, pak choy, cabbage, radish, etc. After the onset of clubroot, the main root and lateral root of the plant swell to form tumors or chicken intestinal roots of different sizes. The shape and size are greatly affected by the planting site. The tumors on the main root are mostly close to the upper part, spherical or nearly spherical, and the surface is uneven. , Rough, and sometimes the epidermis cracks in the later stage; the tumors on the lateral roots are mostly cylindrical or finger-shaped. There are also some plants that after the onset of the disease, the upper part of the main root is stimulated by the pathogen, and ma...
