ATHLETIC FIELDS: In general, weed populations in athletic fields
visited by the consultant were relatively low,
ranging from approximately 5% to 25% of the total
turf area.

Exceptions to this general observation occured at
McLane and Cedar fields where the turf had

sustained moderate to extensive damage due to heavy
use by adult soccer players during inclement weather.
Although high weed populations were not yet evident
at these sites, it can be assumed that the many
openings in the turf will be colonized by weeds
unless remedial action occurs.

Mejor weed species observed in the turf included the
following perennials: - Common Dandelion (Taraxacum
officinale), English Daisy (Bellis ‘perennits), and:
Plantain (Plantago spp.). As the soil warms, no doubt
other species, particularly annual weeds, will become
” apparent. : .

_ When weed populations in turf are increasing or. already
are at high levels, it is usually due to the fact that
competing turf grasses have been thinned out by stress,
leaving openings to be colonized by weeds. Common sour-
ces of stress on turf include: ,
