Abstract/Contents:"An unirrigated bluegrass sod mowed 1½ to 2 inches high was used as the test area. There was a mixed population of Digitaria sanguinalis and D. Ischaemum. Treatments were applied as an aqueous spray at the rate of 2.3 gal./1000 sq. ft. The degree of control was estimated by sampling five - 1 sq. ft. areas on each lot of 4 replications. The early post emergence treatments were started June 12, and the late treatments started July 25. Percent crabgrass and percent bare ground Oct. 4, 1957. [Table] There was some injury to bluegrass with DSMA in the late post emergence test. There was no injury other than discoloration in the early test. While there was less crabgrass at the end of the season on the best late treatments the turf treated early had a better appearance throughout the season. Trichlorisobutyric acid showed promise for controlling crabgrass with both early and late treatments. A pre-emergence test on an area with an erratic crabgrass stand gave no significant control of crabgrass. Materials used were lead arsenate, Pax, NPA CDAA and CDEC"
