抄録

Propargyl N-(6-ethyl-5-iodo-2-pyridyl)carbamate (PEIP) exhibited high fungitoxic activities against Erysiphe graminis f. sp. tritici, Sclerotinia sclerotiorum, Botrytis cinerea, Pyricularia oryzae, and Rhizoctonia solani at 0.1ppm in vitro and 8 to 63ppm in vivo. It also showed activity against benzimidazole-resistant isolates of B. cinerea as well as the sensitive isolates. PEIP possessed not only preventive activity, but also curative activity and translaminar action. The excellent activity of PEIP against B. cinerea and Elsinoe ampelina was also confirmed in field trials. PEIP induced morphological changes in the conidial germination and nuclear arrangement in germ-tubes of B. cinerea in a similar manner to that of benomyl, a benzimidazole fungicide. These results suggest that PEIP interferes with the cell division of this fungus.
