Abstract

Preemergence herbicides for the control of crabgrass, (Digitaria ischaemum (Schreb.) Muhl. and D. sanguinalis (L.) Scop.) were applied on bluegrass sod at three different rates for three years to determine residual effects on the stand and vigor of perennial ryegrass, red fescue, tall fescue, and Merion and common Kentucky bluegrass seedlings. With few exceptions, the herbicides retarded stand and vigor of these turfgrasses seeded in turf killed with methyl bromide. Chlordane was least and a commercial arsenic complex plus 7% N most toxic to young seedlings. Seedlings of Merion Kentucky bluegrass were most resistant to herbicide injury. No appreciable decrease in original turf density was noted except for the arsenic complex material which severely injured bluegrass turf at the two heavier rates.

Germination of the same turfgrasses seeded in flats of sterilized soil in the greenhouse 1 day, 41 days, and 93 days after the application of preemergence crabgrass herbicides, showed the most reduction in emergence from treatments with DMPA [O-(2,4-dichlorophenyl) O-methyl isopropylphosphoramidoate], trifluralin (2,6-dinitro-N,N-di-n-propyl-alpha-alpha-alpha-trifluro-p-toluidine), DCPA (2,3,5,6-tetrachloroterephthalic acid), and dipropalin (N,N-di-n-propyl-2,6-dinitro-p-toluidine). Lead arsenate was least injurious to germinating seedlings. Tall and red fescue were more tolerant to herbicides than the other grasses studied.
