An evaluation was made of four different implements for weed control at three growth stages, between and within rows, at two different speeds and two different crops. Canola was chosen as the weed and cultivation took place at 2-leaf, 5-leaf and 8-leaf stage of growth. Of the four weeding mechanisms assessed on the corn and soybean fields, sweep and row cultivators were the most effective in reducing the number of canola plants between rows. The tine weeder was effective only during the 2-leaf stage of the canola growth for both fields. The rotary hoe gave disappointing results. Velocity does not show statistically significant differences with the exception of the rotary hoe at the 5-leaf stage on the corn field, where low velocity gave best results. Within the row, the tine weeder when used at 2-leaf stage was the most effective implement in both velocities and fields.
