Abstract
ABSTRACTA review of published information on the growth and productivity of Poa trivialis in relationship with perennial ryegrass is presented. The available evidence indicates that P. trivialis is usually out‐yielded by ryegrass, particularly under drought and infertile soil conditions. In addition, the quality and seasonal distribution of the yield is often of questionable value. It would therefore appear that P. trivialis can be considered an undesirable species in most intensively managed ryegrass pastures. Preliminary results from competition studies between F. trivialis and S23 perennial ryegrass confirm that the replacement of ryegrass by P. trivialis leads to a lowering of productivity. The latest control measures for preventing the invasion and/or removal of P. trivialis from ryegrass pastures are given, based largely on the use of selective herbicides.
