Abstract/Contents:"The following chemicals were applied to bluegrass turf for crabgrass control: Potassium cyanate, organic mercury compounds, TCA, also S-1998, S-1980, L2687, L2988, all petroleum fractions. Applications were made to crabgrass when it was in the two leaf stage of growth. Plots were originally treated on June 25 and retreated on July 11, 1949. Effectiveness of these chemicals was measured by percent control of crabgrass and percent discoloration of turf. When manufacturers recommended rates were used the most effective chemical was S1998 which eliminated 90 percent of crabgrass after two applications. Other petroleum products were not particularly effective in these tests, however, rates were not varied enough to establish inferiority or superiority of these chemicals. Two mercuric compounds gave 75 percent control of crabgrass after two applications. TCA caused severe injury to desirable turf species at the rates used in these trials. Potassium cyanate when used at rates sufficiently heavy to eliminate the crabgrass, burned the desirable turf. Bluegrass recovered from this burning effect in about one week."
