Abstract/Contents:"Certain light oil fractions have been found to be toxic to crabgrass at rates which are not injurious to desirable lawn grasses. Two of these, very low in aromatic content, designated by the code numbers L-2687 and L-2988 were given extensive trials at various rates and in combination with other herbicides on lawn plots. Three applications of either fraction at 80 gal. per acre prevented crabgrass from making any appreciable growth and suppressed seed formation. These applications were made when crabgrass seedlings were visible among desirable grasses. One application of 120 gal. per acre at the time when seed stalks were beginning to form killed 80% of the crabgrass plants and prevented seed formation. The addition of dinitros, PCP, TCA, Chlorosol A, IPC and cyanate increased the toxicity to crabgrass but also caused injury to the lawn grasses."
