PROBLEM TO BE SOLVED: To provide a seed disinfection formulation which is useful for high concentration dilution, has good adhesivity to the seeds, does not dust the water- dispersible powder, when prepared into a high concentration formulation, and does not have a problem on workability and safety. SOLUTION: This seed disinfection formulation for high concentration dilution is obtained by wrapping with a water-soluble film a seed disinfection water- dispersible powder which contains a seed disinfector containing pefurazoate and is useful for the high concentration dilution.
