PURPOSE:A germicidal composition, containing 1-ethyl-1,4-dihydro-6,7- methylenedioxy-4-oxo-8-quinolinecar-boxylic acid and validamycin as an active constituent and effective against bacterial grain rot and sheath blight of rice plants. CONSTITUTION:A germicidal composition containing 1-ethyl-1,4-dihydro-6,7- methylenedioxy-4-oxo-8-quinolinecar-b-oxylic acid and validamycin at 1:0.2-1:10, preferably 1:0.5-1:5 weight ratio as an active constituent in an amount of 0.1-99.9wt%, preferably about 1-90wt% in a formulation. The incorporation of the two kinds of the compounds is preferred for not only improving the efficiency and economic advantage by the simultaneous control of two kinds of blights but also making it possible to reduce the amount of the respective components to be applied thereby, the composition is preferred for aspects of environmental pollution, safety, etc. |
