Hawkeye Perennial Ryegrass is one of the darkest
perennial ryegrass available from Seed Research
of Oregon. It is specially bred for its excellent
winter color and red thread resistance. Unparalleled
endophyte material was utilized in Hawkeye
to insure insect resistance.
HISTORY
Hawkeye originated from a program aimed at
inoculation of the red thread disease. In
the fall of 1996, 17,160 mown spaced plants
were established at Rutgers University based
on their attractive appearances. These were
inoculated with red thread and 37 plants were
selected based on resistance and the retention
of a dark green color in the absence of fertilizer.
Seed was harvested from 29 of these plants
while eight others served as pollinators.
This seed was sent to Seed Research of Oregon
in the late summer of 1998. SRX 4RHT, now
known as Hawkeye, emerged from that trial
the winner.
CHARACTERISTICS
Extremely dark green color, even with reduced
fertility
* High turf quality with a fine leaf texture
and reduced stemminess
* Long term persistence - excellent cold and
hot weather performance
* Excellent winter color and winter density
when overseeded into dormant bermudagrass
* Early spring green-up in northern climates.
Very high spring, summer and fall density
* High billbug resistance due to high endophyte
levels
* Excellent resistance to red thread, snow
mold and brown patch
APPLICATION
Hawkeye's dark green color makes it ideal
for a variety of turf applications. Hawkeye
has shown superior wear resistance and recovery,
making it perfect for sports fields. Blend
Hawkeye with other perennial ryegrasses for
sod production or golf course fairways. It
also can be mixed with Kentucky bluegrasses
and fine fescues for home lawns and commercial
sites. In blends with other perennial ryegrasses
or mixed with Poa Trivialis, its dark green
color and high diseases resistance make it
ideal for overseeding permanent turf.
SEEDING RATE
New turf: 7-9 pounds per 1,000 square feet
or 300-400 pounds per acre
* Overseeding rate: 30 pounds per 1,000 square
feet for golf greens
250-450 pounds per acre for roughs
600-700 pounds per acre on fairways
* Seeds per pound: approximately 250,000
GERMINATION
Emergence in 3-7 days under proper conditions.
First mowing 2 weeks after emergence.
