MANAGEMENT CAN PREVENT DISEASE and spraying your lawn
By Dr. BUI Daniel "X'giiowing common lawn

If your turf has a dead-look
the first thing to do is nothing
until you’ve gotten to the root
of the problem.
You can waste valuable time
and money by spraying your
lawn with a fungicide just be

color discoloration has been
caused by disease. So, before
blaming discoloration on di
sease, make certain your turf
isn’t suffering from chemical
dehydration, insect damage or
from a water shortage.
For example, if your grass is
turning yellow but clover is
normal green, that’s a clue
your lawn isn’t diseased but
needs-nitrogen. Light and dark
streaks of color in your lawn
indicate it needs fertilizer.
Similarly, irregular brown
areas can signal infestation by

YOU NEEDNT
BATTLE
CRABGRASS
Spring is the time to spring
into action against ctabgrass.
Combating crabgrass used
to be a time-consuming and
hopeless task, but you can eas
ily prevent it from dominating
your lawn by applying one ap
plication of a pre-emergent
herbicide before the seedlings
develop.
The key is to do so be
fore three consecutive warm
nights (with temperatures
above 50 degrees) combine
with moist earth to break dor
mancy in crabgrass seed. The
little seedlings emerge as light
yellow-green leaves, rather
wide, and up to one-half inch
long.
You can stop crabgrass be
fore the lilacs bloom this
spring by applying any one of
five major chemicals (Balan,
Dacthal, Betasan, Bandane
and Siduron) to your lawn after
mowing it twice. Apply chemi
cals uniformly by spreading
one-half of the suggested
quantity in one direction, and
the other half by moving
at right angles or crosswise.
That gives your lawn double
coverage.
Crabgrass control is easy to
jverlook in spring because the
weed is an annual and its ini
tial growth is slow. But by
early July, when hot weather
sets in and favors rapid
growth, crabgrass can dom
inate your lawn until the first
frost.
Unless you stop crabgrass
before it starts, it could be dif
ficult to control because it pro
duces thousands of seeds and
must be sprayed frequently for
full control. Since crabgrass
flourishes in sunlight, one de
terrent is to let your grass grow
higher and denser than the
weed.
If a crabgrass problem per
sists annually in your lawn,
perhaps your management
techniques need improving.
When adequate lime and fer
tilizer are used, with high
mowing (ranging from IV2 to
2Vz inches), crabgrass seldom
threatens a lawn □
