The grass is a perennial plant and is used for landscaping in parks and flowerbeds because it is rejuvenated and is always green. It is also used for golf and sports fields. In general, lawns are artificially planted regardless of their native conditions, so many special diseases are caused and damages occur without special management. Therefore, managers spray and manage pesticides and herbicides for grass growth, which causes soil pollution and groundwater pollution.

Therefore, the importance of environmentally friendly methods for grass disease control is emerging, and bio pesticides using microorganisms or viruses are being commercialized for environmentally friendly control. Microorganisms used in biopesticides include Bacillus subtilis, Bacillus pumilus, Bacillus licheniformis, Streptomyces sp. And Agrobacterium sp. Agrobacteriom sp.) And Pseudomona sp., And many studies have been conducted at home and abroad.

However, the microorganisms should be mixed with each other without mutual antagonism, and if one microorganism is used, it takes a long time to release a substance capable of inhibiting pathogens by growing after the microorganisms settle in the soil. . In addition, when the product contains a pathogen suppression product, there is a problem that it is difficult to apply to the field because the dilution drainage is weak. In addition, there is a problem that it is difficult to mass production and preservation.

Dispersants and antioxidants were added as potentiators to enhance the bactericidal effect of the two active ingredients selected in Table 5.

Among the dispersants, polyoxyethylene sorbitan monooleate, polyoxyethylene tridecyl ether, dimethylsulfoxide, olive liquid ( Olive liquid), polyoxyethylene glycerin monooleate and sorbitan monostearate (Sorbitan monostearate) using an experiment was carried out so that the plant extract and vegetable oil can be evenly dispersed, respectively. Dilutions of the individual substances by concentration, mixing and dispersing the results using a microscope showed the best results at 8% or more of polyoxyethylene sorbitan monooleate.

Antioxidants were used to prevent oxidation of plant extracts and vegetable oils, which are effective ingredients, by using various kinds of antioxidants used for cosmetics and foods. Antioxidants include butylated hydroxy anisole, propyl gallete, dibutyl hydroxy toluene, erythorbic acid, and butyl butylhydroquinone (tert-Butyl) The optimal dispersant was selected using hydroquinone, Oxystearin and Disodium Ethylenediaminetetraacetate. Each antioxidant was treated by concentration and mixed with the active ingredient, and then stored at different temperatures and compared with changes in the antimicrobial effect to confirm the anti-oxidation result. Butylated hydroxy anisole was not less than 2%. The antioxidant effect was found to be excellent at.

< Example  7> Formulation  Preparation of fungicides containing additives and stabilizers

Formulation additives are required for the formulation of the two active ingredients, dispersants and antioxidants of the present invention. Therefore, in the mixture of the dispersant and antioxidant selected from Example 6 and the two active ingredients as a formulation additive, various nonionic surfactants were mixed for each concentration to observe the change in physical properties and the formulation additive was selected. As a result, 15% polyoxyethylene lauryl ether, 5% polyoxyethylene monooleate, 5% polyoxyethylene dodecyl mono ether, Effective when 5% of polyoxyethylene castor ether and 10% of polyoxyethylene 1,1,3,3-tetramethylbutyl phenyl ether are mixed There was no precipitation of the components, no separation of the layers, etc.

< Example  8> Preparation of disinfectant according to the final blend

Using the two active ingredients, dispersants, antioxidants and formulation additives selected from the above to prepare a fungicide according to the final formulation. March extract, 25% of lemongrass oil was mixed as an active ingredient. The dispersant was mixed with 8% polyoxyethylene sorbitan monooleate, and the antioxidant was mixed with 2% butylated hydroxy anisole. Formulation additives include: 15% polyoxyethylene lauryl ether, 5% polyoxyethylene monooleate, 5% polyoxyethylene dodecyl mono ether, polyoxyethylene A fungicide was prepared by mixing 5% polyoxyethylene castor ether and 10% polyoxyethylene 1,1,3,3-tetramethylbutyl phenyl ether.
