Abstract

In tests conducted from 1951 to 1961 in the Peace River section of Alberta, 3-(p-chlorophenyl)-1,1-dimethylurea (monuron) was applied to vigorous quackgrass (Agropyron repens (L.) Beauv.) sods on different soils. These tests showed: 1) tillage either before or after application of monuron strongly reduced its effect; 2) when used without tillage it did not matter whether monuron was applied in the early summer or early autumn, but when used with tillage it was best applied in the early summer; 3) 40 lb/A applied without tillage eradicated quackgrass under all conditions except when it was established in an unusually deep and loamy soil; 4) killing quackgrass by monuron usually took 2 years; and 5) lethal rates of monuron prevented quackgrass re-establishment for from 1 to 7 years and satisfactory growth of cereal crops for 10 years or more.
