OBJECTIVE In 1958 an experiment was designed to evaluate the weed. killing efficiency of two soil sterilants,diuron and simaziqe, and to determine the relative extent of sU1"face washing after application. No bi tumencove:r was used on'plots. 1 MATE}{IA.LS ANDMETHODS Diur.on and simazine were each compared at 10, 16, 32 anct64 pounds active material per acre in 10 square-foot plots established on sloping areas. Four replications of each rate were made, with two replicates at one location and the other two each at different locations. The treatments were applied on September 30, 1958. . . . The plots were evaluated for vegetative control and downslope damage outside the plot one year after application (October 8, 1959). Vegetative control was rated as zero for no effective control to 10 for complete weed control. Down-s;lope damage was recorded as the number of feet below plots showing kill of weeds. Ratings were made in October 1959, July 1960 and August 1961. . Table I: Amount of Diuron and Simazine Applied Per Acre on Roadside Slopes in Central Connecticut (September 30, 1958) 391 Lbs. Lbs.
