Oralair(R) Grasses contains a mix of 5 standardised grass allergens: perennial rye grass (Lolium perenne), meadow grass (Poa pratensis), timothy grass (Phleum pratense), cocksfoot
(Dactylis glomerata) and sweet vernal grass (Anthoxanthum odoratum), as a daily dose of 300 IR, so as to mimic patients' natural exposure.
Other pasture mixes for cropping rotations include perennial grasses such as phalaris (Phalaris tuberosa) and cocksfoot
(Dactylis glomerata), sown with either annual clovers or lucerne.
This spring, the Trust and the National Pollen Research Unit are asking people to record the early flowering grasses such as Yorkshire fog, cocksfoot
, meadow foxtail and Timothy grass, as part of the UK Phenology Network's survey, which is monitoring the timing of nature's events in a changing environment.
Two replicates were established of each pasture treatment in 1992 and these were based on either (i) subterranean clover (Trifolium subterraneum), ( ii) lucerne (Medicago sativa), (iii) the perennial grasses phalaris (Phalaris aquatica) and cocksfoot
(Dactylis glomerata), and (iv) lucerne plus the perennial grasses.
Neglected rank grassland dominated by cocksfoot
and false oat grasses is classified as semiimproved as is damp grassland dominated by Yorkshire fog, creeping bent, tufted hair grass which may or may not have frequent tussocks of soft rush.

and annual pastures in north-eastern Victoria.
The soil was also a Temuka silt loam, and the sampling locations had a grass cover that was 60% cocksfoot
, 20% perennial ryegrass, and 20% Yorkshire fog.
Highly allergenic rye blooms from May to June and from May to August is the flowering period for meadow grasses such as timothy, sweet vernal grass and cocksfoot
A field trial was established in winter 1998 on Ashhurst silt loam (Typic Orthic Brown Soil) at Massey University Farm, Palmerston North, at a flat site under continuous long-term pasture (mainly Yorkshire fog, cocksfoot
, perennial ryegrass, white clover, and browntop) grazed by sheep.
