Abstract/Contents:"An unirrigated bluegrass sod was treated with disodium methylarsonate, 8 lbs/A; 3,4-Dimethylbenzophenone, 4 ad 6 lbs/A; and PMA (dry), 1 lb/A. Each material was applied at the above rates on June 25, July 5, and July 11. Spray applications at 100 gals./A were made except or PMA. Disodium methylarsonate gave excellent control of crabgrass but there was permanent injury to small areas of bentgrass in the sod in addition to discoloration of the entire sod. Neither of the other materials gave consistent satisfactory control of crabgrass. In another test, disodium methylarsonate; 8 lbs/A; PMA (dry), 1 lb/A; and KOCN, 8 lbs/A were applied July 26, August 1, and August 8 on a bluegrass sod. Method of application was the same as described above. Complete control of crabgrass was obtained with disodium methylarsonate but with serious injury to bluegrass. Both PMA and KOCN gave partial control with PMA giving better control in this test."
