PURPOSE:To strength the potency of a benzimidazole disinfectant against resistant Gibberella fujikuroi by adding a specific aliphatic monocarboxylic acid or aromatic monocarboxylic acid to a paddy rice benzimidazole disinfectant having a remarkably reduced potency against rice disease resistant strains. CONSTITUTION:A 1-6C aliphatic monocarboxylic acid or 7-10C aromatic monocarboxylic acid (e.g., acetic acid, propionic acid or benzoic acid) is added to a paddy rice benzimidazole seed disinfectant (namely a mixed agent containing a benzimidazole fungicide, benomyl, thiophanate methyl or thiabendazole) especially having a remarkably reduced potency against resistant rice gibberella fujikuroi preferably is an amount of 1-100 pts.wt. of the carboxylic acid based on 100 pts.wt. of the benzimidazole disinfectant. |
