S. Mitani et al., BIOLOGICAL PROPERTIES OF FUNGITOXIC PROPARGYL N(6-ETHYL-5-IODO-2-PYRIDYL)CARBAMATE, Nippon Noyaku Gakkaishi, 20(2), 1995, pp. 153-160
Propargyl N-(6-ethyl-5-iodo-2-pyridyl) carbamate (PEIP) exhibited high
fungitoxic activities against Erysiphe graminis f. sp. tritici, Scler
otinia sclerotiorum, Botrytis cinerea, Pyricularia oryzae, and Rhizoct
onia solani at 0.1 ppm in vitro and 8 to 63 ppm in vivo. It also showe
d activity against benzimidazole-resistant isolates of B. cinerea as w
ell as the sensitive isolates. PEIP possessed not only preventive acti
vity, but also curative activity and translaminar action. The excellen
t activity of PEIP against B. cinerea and Elsinoe ampelina was also co
nfirmed in field trials. PEIP induced morphological changes in the con
idial germination and nuclear arrangement in germ-tubes of B. cinerea
in a similar manner to that of benomyl, a benzimidazole fungicide. The
se results suggest that PEIP interferes with the cell division of this
fungus.
