Abstract/Contents:"A common problem in establishing ground cover plantings is the control of weeds during the initial establishment phase. Many of the herbicides commonly used on woody ornamentals have caused crop injury. A comparison was made using 5 herbicides at various rates and in combinations on eight species of ground covers. In 1970, the herbicides were applied in the spring of plantings made the previous fall. Winter weeds that had already germinated reduced the effectiveness of most herbicides. In the spring of 1971 the herbicides were applied two days after peat potted plants were set in a weed-free bed. The herbicides used were granular formulations of simazine 1 lb/A, simazine 1 lb/A plus diphenamid 4 lb/A, diphenamid 4 lb/A, simazine 1 lb/A plus alachlor 4 lb/A, alachlor 2 and 4 lb/A and the wettable powder formulation of chloroxuron 4 and 6 lb/A. The species used were Euonymus fortuneii 'Longwood', Potentilla tridentate, Potentilla verna, Ajuga metallica 'Crispa', Hedera helix 'Thorndale', Vinca minor 'Bowles', Pachysandra terminalis, and Euonymus fortuneii vegatus. The most satisfactory weed control with the least crop injury was achieved with alachlor. The dominate weed species were the grasses Echionochloa crusgalli (barnyard grass) and Digitaria sanguinalis (crabgrass) and the broadleaves Chenopodium album (lambsquarter Ambrosia artemisifolia (ragweed) and Portulaca oleracea (purslane). A wide assortment of other broadleaf weeds appeared throughout the growing season. The growth of Ajuga was reduced by all herbicides but not significantly with alachlor or diphenamid. Simazine and all combinations of simazine injured Euonymus species. Tenoran injury was exhibited as a foliage discoloration in all species, and reduced growth except with Hedera helix and Pachysandra terminalis."
