Description of the Related Art Snow rot is a disease peculiar to turfgrass in a snowy area of a cold region, and depending on the type of causative pathogen, black small grain sclerotium, brown small grain sclerotium, brown snow rot, etc. Types are known. Black small grain sclerot and brown small grain sclerot are often found in regions with a large amount of snow and a short period of soil freezing, and the turfgrass turns white after death and becomes dead grass. It is a disease in which a nucleus is formed. Brown snow rot is a disease that often occurs in regions with heavy humidity and heavy snowfall, and turfgrass becomes brown and soft rots after snow is thawed.

Antibacterial activity test of thorium The antibacterial activity was tested using turfgrass leaves (cultivar: Pencrosvent). That is, the bent turf leaves are cut into a length of 30 to 50 mm, packed in a petri dish and sterilized, and sodium carbonate is added at 5, 10 and 20 g per m 2, and the amount of water sprayed is 600.
It was sprinkled on the leaves of the grass in the petri dish so that the amount of each of them became 800 ml. Immediately after that, POD (Potato Dextrose Agar) pre-cultured the black small-grain sclerotium and the brown small-grain sclerotium with a circle diameter of 5
The lawn was cut out with a mm cork borer and transplanted to the center of the petri dish. Culturing was performed in the dark at 4 ° C., and after one month, the diameter of the flora was measured and the inhibition rate was calculated by the following formula.
