Barnyardgrass (Echinochloa spp.) is one of the most common and troublesome weeds in paddy rice cultivation. For effective barnyardgrass control, herbicides with high efficacy against the weed and good selectivity for rice are required. 1-Phenyl-5(4H)-4-dialkylcarbamoyltetrazolinones exhibited high activity against barnyardgrass in paddy field experiments. Fentrazamide, 4-(2-chlorophenyl)-N-cycl...

an isolated fusarium anthophilum (a. braun) wollenweber (isolate 16c) has been considered as a candidate for microbial control of barnyard grass [echinochloa crus-galli (l.) p. beauv]. the effects of nutrition on conidiation, germination rate and germ-tube elongation of conidia of the fungus were evaluated. conidia yield, conidial germination and conidial germ-tube elongation of the fungus grow...
