Abstract
With an intention to get herbicide harmless on cultivated vegetables Actinomyces was screened from the soils of various parts of Japan using radish and barnyard grass as a typical vegetable and weed. Culture filtrate of 58 strains out of 617 isolates inhibited the germination of both radish and barnyard grass sambau or independently 12 were positive for both radish and barnyard grass and 3 were positive only for barnyard grass. Seven strains which showed high activity at 160 times dilution were subjected to herbicide activity test under both paddy and try conditions using popular weeds barnyard grass smallflower umbrella amant pickerel weed bulrush crab grass bearded knot-weed slender amaranth pickerel weed bulrush crab grass bearded knot-weed slender amaranth umbrella sedge and shiroza. Only one 422-25 strain showed herbicide activity under field conditions. A substance responsible for the herbicide activity has been purified from the culture fluid of 422-25. On the basis of chemical FAB-Mass 13C-NMR and IR analyses the substance has been identified as Hygromycin B
