Abstract/Contents:"Three experimental and six registered preemergence herbicides were evaluated in two studies to determine their effect on smooth crabgrass (Digitaria ischaemum (Schreb.) Muhl.) germination, turfgrass quality, root activity and germination of overseeded 'Kenblue' Kentucky bluegrass (Poa pratensis L.). Materials were tested on Kentucky bluegrass - red fescue (Festuca rubra L.) turf. Granular formulations of A-820 (N-sec-butyl-4-Tertiary butyl 2,6-dinitro aniline), CGA 10832 (N-n-propyl-N-cyclopropylmethyl-4-trifluoromethyl- 2,6-dinitro aniline) and AC 92390 (N-sec-butyl-2,6-dinitro- 3,4-xylidine) at rates of 6, 2 and 3 lb (a.i./A) respectively, provided satisfactory smooth crabgrass control. Root numbers were reduced at the 3" depth following 7 years of continuous bandane (polychlorodicyclopentadiene isomers) and tricalcium arsenate application. Bensulide (O,O-diisopropyl phosphoro dithioate S-ester with N-(2-mercaptoethyl) benzenesulfonamide)), (tricalcium arsenate) and A-820 (2.3G) provided the best combination of crabgrass control and turfgrass quality in the 1972 tests. Germination of overseeded Kentucky bluegrass was significantly reduced by continuous applications of bensulide and bandane."
