Microbial agent capable of preventing both root knot nematode disease and clubroot and application of microbial agent

Abstract

The invention discloses a microbial agent capable of preventing both root knot nematode disease and clubroot and application of the microbial agent, and relates to the 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 invention relates to a microbial agent capable of preventing both root knot nematode disease and clubroot disease. The microbial agent is a composite microbial agent prepared by compounding bacterial powder of bacillus methylotrophicus, paecilomyces lilacinus and bacillus subtilis. According to the microbial agent capable of preventing the root-knot nematode disease and the clubroot, the three strains are compounded for use, effective prevention and control of the clubroot, activation of soil nutrients and growth promotion of crop root systems can be achieved in the early stage of use, then root-knot nematode can be effectively inhibited, meanwhile, growth and development of the crop root systems are further promoted, and the yield of crops is increased. After the diseases are effectively prevented and controlled, the nutrient absorption of crops is enhanced, and the yield loss of the crops caused by the diseases is further reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial inoculant for preventing both root-knot nematode and clubroot and application thereof. Background technique [0002] With the rise of organic agriculture, green prevention and control methods are used more and more in agriculture. Among them, the use of microorganisms for disease prevention and control is a more common and effective technical means. However, in the current agricultural disease prevention and control, a biological control product generally only acts on one disease. If the type of disease cannot be accurately identified when used in the field, it often occurs that the disease cannot be accurately controlled, especially for the symptoms of the disease. For similar diseases, if there is no rapid detection technology in the field, it often leads to the wrong choice of drugs and delays the timing of prevention and control. [0003] Based on the current...

Problems solved by technology

[0007] The purpose of the present invention is to propose a microbial agent for both preventing root-knot nematode and clubroot and its application, which solves the problem of similar field symptoms of root-knot nematode and clubroot in the prior art, which is difficult to quickly distinguish and accurately select agents As well as the technical problem that root-knot nematode and clubroot disease tend to occur simultaneously and are difficult to prevent and control in time
