Abstract/Contents:"An unirrigated golf course fairway mowed regularly to 1 ¼ inch was used for tests (a) and (b). The permanent sod consisted chiefly of bluegrass with small patches of bent. Test (c) was on bluegrass mowed 2 inches high. Except where noted, treatments were applied as an aqueous spray at the rate of 2.3 gal/1000 sq. ft. All plots were 100 sq. ft. The degree of control was estimated by sampling five - 1 sq. ft. areas on each plot. The results of tests (a) and (b) are shown in the Tables I and II. There was no injury to desirable grasses for any treatment other than very slight temporary discoloration. Test (a). The first application of each treatment was made on May 8, before crabgrass germinated. Subsequent applications were made 6 weeks later where 2 applications were applied and 5 and 10 weeks later where 3 applications were applied. The NPA was a dry form for spreader application (Alanap 1F). Test (b). The first application was made June 21. The crabgrass was in the 3 to 4 leaf stage. Subsequent applications, when applied, were made 1 week apart. Test (c). The first application was made July 10. Four additional applications of all treatments were made 1 week apart. Treatments were Disodium Methylarsonate-hexahydrate, spreader application, 2.25 oz./1000 sq. ft.; PMA spreader application, 0.38 oz./1000 sq. ft.; DSMA, 2 oz./1000 sq. ft.; PMA, 0.18 oz./1000 sq. ft.; Sodium arsonacetate, 1 oz./1000 sq. ft. PMA in both forms of SMA as a spray gave good control. DSMA applied dry was less effective. Sodium arsonacetate gave some reduction in crabgrass but not a satisfactory degree of control."
