| Abstract/Contents: | "Digitaria didactyla Willd. (blue couch) is a warm-season turfgrass well adapted to use in low maintenance lawns, parks and golf fairways on well-drained acid infertile light-textured soils in humid subtropical and tropical climates with mild winters and an absence of heavy frosting. In Australia, D. didactyla includes material from two different genetic sources: Queensland blue couch from widely naturalised material accidentally introduced from the Mascarene Islands or Madagascar in the early 19th century; and Swazigrass from deliberate introductions of the former D. swazilandensis (native to mainland southern Africa) in the mid-1960s. Two cultivars, 'Aussiblue' and 'Tropika', derived from Swazigrass germplasm have been released in the past 20 years. Blue couch is less drought hardy than Cynodon dactylon (L.) Pers., but recovers quickly once drought stress is removed. It is tolerant of temporary, though not permanent, waterlogging, but has a low tolerance of salinity. While Queensland blue couch is among the least shade tolerant warm-season turfgrass species, Swazigrass does tolerate moderate levels of shading. Propagation is usually by vegetative means, though limited supplies of Queensland blue couch seed are also available. Blue couch has a low fertility requirement, and can invade and replace C. dactylon under low nutrition on acid infertile soils. It is prone to iron deficiency, especially after heavy rainfall. Blue couch is lower thatching and less prone to scalping than C. dactylon, but is also less tolerant of wear than the latter. Lawn armyworm and sod webworm caterpillars are the main pests, with dollar spot the major disease of concern. Most standard broadleaf herbicides can be safely used with blue couch, and fluazifop has shown promise for selective control of other grasses." |
