专利汇可以提供Controlling method for injurious nematode of crop专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce the damage by nematodes greatly, by raising seedling of crops in bed soil containing nematode predatory germs in a high concentration, carrying the bed soil as a holding soil with the seedlings in a planting soil in the transplanting, and making the nematode predatory germs present in the rhizosphere soil in an effective state.
CONSTITUTION: Seeds of crops are sown in bed soil containing nematode predatory germs or seedlings are transplanted thereto and raised for a given period to make the nematode predatory germs present around the extending roots in a sufficiently effective state. The bed soil is then carried in a planting soil with the seedlings as a holding soil to control the nematodes. A porous material, e.g. vermiculite or smoked chaff charcoal, is mixed with a mountain sand or river sand without pathogenic germs to give a fertilizer, which is used as the bed soil. Nematode predatory germs, e.g. Dactylella ellipsospora, belonging to the subclass Hyphomycetes of the class Fungi Imperfecti (Deuteromycetes) are cultivated suitable and mixed with the fertilizer in an amount of about 10
