In order to investigate the effects of different pesticides on weeding of barnyard grass on direct seeding paddy field, an investigations was made on the effects of weeding of barnyard grass on direct seeding paddy field by choosing 7 kinds of chemicals and setting 9 treatments. The results showed that the average of the control effects was between 19.9%~94.6% after ten days of spraying,but the average of control effects was between 22.7%~98.2% after twenty days of spray-ing. It showed that the control effects on weeding of barnyard grass were different with different pesticides. The results of variance analysis of the control effects showed that the differences between the different plots were not significant but the differences between different treatments were significant. It showed that the differences of weeding effects between different pesticides were very significant.
