PROBLEM TO BE SOLVED: To provide an agricultural and horticultural disinfectant (new seed disinfectant) which is excellent in permeability into deep-infected seeds and the like, has more excellent disinfecting power than those of conventional commercially available cupper disinfectants, can effectively control any of infectious fungal seed diseases, infectious bacterial seed diseases, and nematode (especially Aphelenchoides besseyi Christie) diseases, and can effectively disinfect various resistant microbes at low doses.SOLUTION: This seed disinfect is characterized by containing silver-carried zeolite, and pefurazoate (pent-4-enyl-N-furfuryl-N-imidazol-1-ylcarbonyl-DL-homoalaninate) as an active ingredient. It is desirable that the content of silver ion in the silver-carried zeolite is 0.1 to 15.0 wt.%, and it is desirable that the content of the pefurazoate is 1 to 200 pts.wt. per 100 pts.wt. of the silver-carried zeolite.COPYRIGHT: (C)2008,JPO&INPIT【課題】深部感染種子等への浸透性に優れ、従来市販されている銅殺菌剤よりも殺菌力に優れ、種子伝染性糸状菌病や細菌病および線虫(特にイネシンガレセンチュウ)病害の何れをも効果的に防除でき、低薬量で各種耐性菌をも効率よく殺菌できる農園芸用殺菌剤(新規種子消毒剤)の提供。【解決手段】銀担持ゼオライトと、ペフラゾエート(ペンタ-4-エニル-N-フルフリル-N-イミダゾール-1-イルカルボニル-DL-ホモアラニナート)とを有効成分として含有してなることを特徴とする種子消毒剤。上記銀担持ゼオライトの銀イオンの含有量が0.1~15.0重量%であることが望ましく、また銀担持ゼオライト100重量部に対して、上記ペフラゾエートの含有量が1~200重量部であることが望ましい。【選択図】なし
