MICROORGANISM OF GENUS COLLETOTRICHUM, HERBICIDE FOR ANNUAL BLUEGRASS CONTAINING THE MICROORGANISM AND METHOD FOR CONTROLLED ANNUAL BLUEGRASS

摘要

PURPOSE:To obtain a controlling agent exhibiting herbicidal activity exclusively against annual bluegrass by incorporating microorganisms of the genus Colletotrichum free from pathogenicity to useful plants and exhibiting pathogenicity to the plants of the genus Poa. CONSTITUTION:Microorganisms of the genus Colletotrichum free from pathogenicity to useful plants and exhibiting pathogenicity to the plants of the genus Poa are used as the active component. Colletotrichum P-191 (FERM BP-4264) can be mass-cultured to easily get a large amount of spores.
