Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid plant activator suitable for use in preventing turfgrass diseases in golf courses.

[0002]

2. Description of the Related Art Management of turfgrass on a golf course is not easy.
Soil pathogens that kill turfgrass include filamentous fungi such as Fusarium-based, Rhizoctonia-based, Pistium-sprite-based, and Hirmintsporium-based. These filamentous fungi directly affect turfgrass and kill them. Basidiomycetes such as Drosophila communis, Komurashimejimeji and Shibafuchi mushrooms form a thatch layer consisting of a thick hypha layer in the soil below the roots of turfgrass. There may be a situation where the lawn grass suddenly withers.
In order to prevent such a situation, golf courses are taking measures such as injecting various chemicals into the soil.

[0003]

However, it is a well-known fact that the use of various chemicals on golf courses causes water pollution. Moreover, even if these chemicals are used, harmful fungi cannot be completely exterminated. Particularly, there is a problem that the chemical agent becomes resistant to the filamentous fungus after being used several times, and the effect gradually diminishes. By the way, a large amount of broth of beans is discharged from the miso and tofu manufacturing companies. This bean broth is used as a fertilizer because it contains a lot of sugar and protein, but it is actually discarded because it has a bad odor. However, even if it is disposed of, it cannot be discharged directly to a river, etc.
Since there is a large amount, there is a problem that purification treatment requires a great deal of cost.

Therefore, the present invention has been made to solve the above problems, and an object thereof is to effectively use bean broth and to exterminate harmful fungi in turfgrass on a golf course. It is an object of the present invention to provide a liquid plant activator which can be suitably used and which can give activity to plants and cause good growth.

[0005]

The present invention has the following constitution in order to achieve the above object. In other words, in the bean juice,
Inoculate with three species of bacteria, including kteria, yeast, and filamentous fungi
Ferment and add acid to the fermented product to adjust pH to 4-5
A liquid plant active agent obtained by inoculating and growing Trichoderma lignorm . It is preferable to add ammonium phosphate or potassium phosphate to the fermentation product.

[0006]

[Function] As described above, the broth of beans contains abundant sugars and proteins. However, sugars are polysaccharides mainly composed of pentasaccharides and are difficult to be absorbed by plants as they are. Therefore, in the present invention, first, the broth of beans is inoculated with a fermentation bacterium to ferment it. As the fermentation bacterium, so-called three kinds of bacteria in which bacteria, yeast and filamentous fungi are mixed may be used. Commercially available products can be used for these three species. The fermentation process may be performed under normal fermentation conditions. When the temperature is high in summer, the fermentation is completed in about one week under the outside temperature. It takes about one month when the temperature is low such as in winter, but the fermentation may be promoted by appropriately heating. By these three species, sugars mainly composed of pentasaccharides are decomposed into glucose and fructose monosaccharides, and various amino acids are produced from proteins. In addition, trace amounts of so-called annon substances such as vitamins, nucleic acids and various hormones are produced.

[0007] Bacteria and yeast contribute in the initial stage of fermentation, and filamentous fungi grow in the final process of fermentation. The growth of this filamentous fungus is the Trichoderma lignor in the present invention.
It becomes a great thing as a free medium bacteria. Trico del Malig
Norm bacteria grow at a PH of about 4-5. After completion of the fermentation, the pH is about 5.5 to 6.2 due to amino acids, so an acid such as an organic acid is added to adjust the pH to a range of 4 to 5, preferably about 4.5. As the organic acid, citric acid, malic acid or the like can be used. Further, it is preferable to add ammonium phosphate and potassium phosphate containing phosphorus, which is an active ingredient of the plant.

Thus, the fermentation medium in which the pH is adjusted to about 4 to 5 is inoculated with the Trichoderma lignorm bacterium and cultured. Trichoderma lignorm grows using filamentous fungi as a nutrient source. As described above, since a large amount of filamentous fungi grows in the fermentation medium at the end of fermentation, Trichoderma lignorm bacterium proliferates with this filamentous fungus as a nutrient. This Trichoderma lignorm bacterium grows for about one week under the outside temperature in summer. In this way, a liquid substance (liquid plant activator) is obtained. In the liquid substance, Trichoderma lignorm bacterium is proliferated as described above, and in addition, monosaccharides and amino acids produced in the fermentation process, as well as various vitamins, nucleic acids and hormones are contained.

The above liquid plant activator is sprayed in soil,
Although it may be infiltrated, it may be sprayed directly on the plant body. When sprayed directly on the plant, the liquid phytoactive agent contains the saponin contained in the broth of beans as it is, so the surface-active effect of this saponin wets the paraffinic leaf surface and leaves Makes absorption from the surface easy. From the leaves, monosaccharides such as glucose and fructose having a small molecular weight, amino acids, and added ammonium phosphate are easily absorbed. The amino acid produced by fermentation of the broth of beans contains a large amount of brolin, and this brolin has a photosynthesis promoting action. Brolin absorbed from the leaf surface promotes photosynthesis in leaves, whereby sugars are synthesized and the synthesis of cellulose that constitutes a plant is promoted. That is, the presence of sugars directly absorbed from the leaf surface and the sugars synthesized by photosynthesis enhance the growth of plants. In addition, phosphorus absorbed from the leaf surface and phosphorus absorbed from the soil act on sugars to promote the synthesis of adenosine triphosphate, which is an energy source of the plant. Thus, the absorption of amino acids, ammonium phosphate, or potassium phosphate from the leaf surface has an extremely large effect on the activity of the plant body. For example, when a phosphorus compound is directly supplied into the soil as a nutrient source of a plant, it becomes a phosphate ion in the soil and is combined with a metal such as aluminum or iron in the soil to form a compound insoluble in water. It will not be absorbed by the body. Incidentally, when the phosphorus compound is directly supplied to the soil, the amount of phosphorus absorbed by the plant is said to be about 15% of the whole. In this respect, the liquid plant active material of the present invention has extremely high absorption efficiency because phosphorus is absorbed from the leaf surface.

On the other hand, the liquid plant active agent dripped from the leaf surface or the liquid plant active agent sprayed in the soil penetrates into the soil, and the Trichoderma lignorm bacterium is Fusarium-type, Rhizoctonia, which is a disease bacterium in the soil. System, Pythium sprite type, Hirmint sporium type filamentous fungi and Pleurotus ostreatus, Komurashimejimeji, acting on basidiomycete fungi (filamentous fungi) such as Shibatatake, grows as a nutrient
It suppresses the growth of these pathogenic bacteria. As a result, very good results were obtained for the grass on the golf course, and it was possible to prevent death. Moreover, since Trichoderma lignorm bacterium uses the disease-causing bacteria as a nutritional source, unlike the chemicals, it does not cause resistance to the disease-causing bacteria, and its exterminating effect continues for a long time. Therefore, the effect can be sustained even if the spray amount is not so large.

Trichoderma lignorm is also a type of filamentous fungus. Generally, in soil, bacteria, microorganisms,
Although the filamentous fungus maintains its delicate balance and maintains its ecosystem, the Trichoderma lignorm bacterium does not affect other bacteria or microorganisms, and the above-mentioned Fusarium strain, which is a disease bacterium exclusively, Rhizoctonia strain, Acting on filamentous fungi such as Pythium sprites, hirumintosporium, etc. and basidiomycetes (filamentous fungi) such as Drosophila communis, Komurasakisimeji, Shibatatake, etc., and since it serves as a nutrient source, bacteria, microorganisms, The balance of the entire ecosystem such as filamentous fungi is maintained and the ideal soil form is maintained. Trichoderma lignorm does not form a thatch layer and does not kill grass. In addition, since the liquid botanical active agent contains nutrients such as amino acids, monosaccharides, vitamins, nucleic acids and hormones which are easily absorbed as described above, it has a great fertilizing effect on plants.

[Example] Bean broth discharged from a miso manufacturing plant 10
When 3 kg of three commercially available strains were inoculated to 00 kg and fermented under the outside temperature in the summer, the fermentation was completed in about 1 week, and a liquid fermented product in which a large number of filamentous fungi were propagated was obtained. Ammonium phosphate was added to the liquid fermented product, and an acid was further added to adjust the pH to about 4.5, and then the liquid fermented product was added.
When 10 Kg of Trichoderma lignorm bacterium was inoculated and cultivated at ambient temperature, the bacterium Trichoderma lignorm proliferated greatly, and the culturing was completed in about 1 week to obtain a liquid plant active agent. When this liquid botanical activator was sprayed on a turfgrass in the golf course where a filamentous fungal layer was formed in the lower layer and was dying, the turfgrass was revived and grew vigorously. When the above liquid plant activator was sprayed during the process of cultivating vegetables such as Chinese cabbage and cabbage, the growth was vigorous, and large vegetables such as Chinese cabbage and cabbage could be grown. Fusarium-type and Rhizoctonia-type pathogens as well as disease-causing fungi such as white silkworm inhabit the field, and Trichoderma lignorm bacillus also kills these pathogens.
