Definitions
- the present invention relates to the production of an absolutely parasitic natural enemy microorganism of a plant parasitic nematode that causes damage to crops.
- this microorganism it is slightly vegetative near the soil of the cultivated crop. It is common practice to inoculate a nematode infested with a substance, cultivate it for a long period of two months or more, and collect microorganisms that have grown from the roots. However, its production efficiency is low and it cannot be used for agricultural production. In addition, plant roots or simple root systems transformed with Agrobacterium are aseptically cultured on agar or other media, and nematodes infested with microorganisms are aseptically inoculated and controlled. Although it is possible to grow them in a confined environment, the productivity is not better than that using soil.
- the nematode infestation site is limited only to the vicinity of the root growth point, and there is a limit to the response depending on the cultivated area and the type of plant. Also, due to the large amount of nematode inoculation, large root obstruction caused a serious problem in the roots. Was.
- the inventors of the present invention easily invaded nematodes having natural enemy microorganisms attached not only to the roots, which were conventionally used as production sites, but also to the stems or leaves, and the natural enemy microorganisms were also entrapped there. I found that it could be produced. That is, natural enemy microorganisms adhere to the aqueous solution of polysaccharides and their derivatives, suspend fe-parasitic nematodes, and soak the whole plant. Or spray this nematode suspension. It may be lighter than water Buries the whole plant in an organic carrier and inoculates a nematode to which natural enemy microorganisms adhere from above. By these methods, nematodes to which natural enemy microorganisms adhere are infested on leaves and stems.
- the present inventors have found that by cultivating under appropriate temperature control, it is possible to obtain a larger number of target natural enemy microorganisms than in the past, and have completed the present invention.
- the present invention is a method for producing a natural enemy microorganism by infiltrating a plant parasitic nematode to which a natural enemy microorganism is attached into the whole plant including the foliage. Then, the plant parasitic nematode to which the natural enemy microorganisms are attached is suspended in the polysaccharide and its derivative to immerse the whole plant, or the nematode is penetrated into the whole plant by spraying it on the whole plant.
- a method for producing natural enemy microorganisms and burying the whole plant in an inorganic or organic carrier lighter than water, suspending nematodes with natural enemy microorganisms attached to water and adding from above, After invading the whole, it removes the carrier and produces nematode natural enemy microorganisms.
- a root-knot nematode or a cyst nematode that is root-fixing is suitable.
- Plants can be used as long as these parasitic plants are used.
- polysaccharides and derivatives thereof to be used include agar, dielan gum and carboxymethyl cellulose.
- organic carrier include micropaloon, which is a burner of coal, coke, and the like, and examples of the organic carrier, include ground rice hulls and peat moss.
- nematodes to which bacteria belonging to the genus Pastria were attached were inoculated as natural enemies.
- the inoculation method was as follows: add a sweet potato nematode with natural enemy microorganisms attached to a 0.2% agar water solution so as to bring the number of insect heads to 600 per 1 m1, and immerse the plant with the microballoons removed. did. This was put in a polyethylene bag and kept moist and allowed to stand at room temperature. This solution was sprayed on the whole plant, similarly placed in a polyethylene bag and kept moist and left at room temperature.
- a microballoon is placed on the plant cultivated by the microphone mouth balloon until the plant is buried, and a nematode suspension solution with natural enemy microorganisms attached is added from above on the plant, and a sufficient amount is rinsed after adding 100 plants per plant. After watering, the nematodes were dispersed in the soil. 2 days after nematode inoculation
