Forty nine N-substituted-α-aminonitriles were prepared and their preventive activities against Fusarium diseases were determined. Relationships between chemical structure and preventive activity were examined and the systemic movement in plants was investigated with 14C-N-allylaminoacetonitrile. Of the compounds tested, N-sec-butyl-α-aminoisobutyronitrile and N-allylaminoacetonitrile were most effective in controlling yellows of the Japanese radish which were caused by Fusarium oxvsporum f. sp. raphani. N-Allylaminoacetonitrile showed remarkable systemic movement and a potent preventive activity against Fusarium wilts of cucumber and tomato not only by the soil drench test but also by the foliar spray assay.
制备了49种代N-取代-α-氨基腈,并测定了它们对镰刀菌病害的防治活性。研究了化学结构与防治活性之间的关系,并使用14C-N-烯丙基氨基乙腈研究了其在植物中的系统运动。在测试的化合物中,N-仲丁基-α-氨基异丁腈和N-烯丙基氨基乙腈对由尖孢镰刀菌萝卜专化型引起的日本萝卜黄化病具有最佳的防治效果。N-烯丙基氨基乙腈显示出卓越的系统运动,对黄瓜和番茄的镰刀菌萎蔫病不仅通过土壤浸渍测试,还通过叶面喷雾法表现出强效的预防活性。
