Abstract/Contents:"In 1954, seven herbicides were applied to bluegrass turf at University Farm to 100 sq. ft. plots replicated four times. Crabgrass began emerging approximately July 1. The following four herbicides were applied prior to crabgrass emergence (June 8.) SES at 8 lb. in 200 gal. water per acre, NP (Alanap) at 8 lb. in 170 gal. water per acre, Chlordane at 15 lb. in 43 gal. non-toxic oil (Barco odorless thinner) per acre, and PAX (containing 13.2% lead arsenate and 3% nitrogen) at 2178 lb. per acre applied dry. A second application of SES, alanap, and Chlordane was made to the same plots one month after the first (July 6.) The following three herbicides were applied twice as post-emergence treatments: Standard Crabgrass Killer at 107 gal. per acre, PMA at 5 pints of 10% formulation in 100 gal. water per acre, and KOCN at 8 lb. in 100 gal. water per acre. The first of these was applied on July 7 and July 22, the latter two on July 7 and July 14. A wetting agent (Igepon AP-Extra) was added to the KOCN solution at the rate of 1 lb. per 100 gal. solution. For all treatments grass was cut to 1 ½" on the day before herbicide application. The pre-emergence treatments (June 8) were followed by the application of approximately one inch of irrigation water on the day following application. Weed counts made on August 3, showed that all herbicides except PAX and Standard Crabgrass Killer had significantly reduced the population of crabgrass plants. The percentages of crabgrass control were as follows: SES-66%, Alanap-75%, Chlordane-66%, PAX-53%, Standard Crabgrass Killer-41%, PMA- 75%, and KOCN-97%. All of the treatments except SES caused some temporary discoloration of the bluegrass. Standard Crabgrass Killer and PAX caused death of bluegrass plants wherever overlapping of the spray occurred."
