Weed occurrence controlled with the timing of herbicide application in waxy corn field was surveyed to know the influences of weed density level to the corn growth and yield-related characteristics. Vegetational feature of experimental plots was characterized as the prevalent occurrence of three weed species, Echinochloa crus-galli, Digitaria sanguinalis, Acalypha australis. E. crus-galli, especially, was dominant over entire experimental period. Vegetational feature of weeds in the corn fields was characterized as the prevalence of Acalypha auatralis in early stages and Echinochloa crus-galli in late stages.
