Terrace Slopes 
Fall is the best time to plant terraces. Since or straw with a wire covering should be used 
these areas are subject to adverse conditions, after seeding. These should be removed as soon 
special care should be exercised in getting the as the grass germinates. Special seeding mix- 
soil in good shape. To prevent washing, a suit- tures containing deep rooted, drought tolerant 
able mulch such as burlap bags, cheesecloth, grasses are obtainable for terraced slopes. 
LAWN PESTS, DISEASES AND WEEDS 
SUBSOIL PESTS 
The major subsoil pests are the Japanese beetle, Oriental beetle, Asiatic garden beetle, 
masked chafer, European chafer, white grub’ and rose chafer. These feed on the roots, 
thereby killing the grass. 
CONTROL—For quick action, apply 5 pounds of 5% Chlordane Dust or 5 ozs. of 40% 
Chlordane Wettable Powder in water per 1000 square feet, preferably in early May. This 
will remain effective for 3 or 4 years. If you prefer slower initial results but wish the residue 
to remain longer, then use 6% lbs. of 10% DDT dust or 14 ozs. of 75% DDT Wettable Powder 
in water per 1000 square feet. The DDT will not control white grubs and is questionable 
on rose chafer. For European chafer, double the quantity of DDT. The chlordane and DDT 
dusts are most easily applied by means of a lawn fertilizer spreader. 
ABOVE-GROUND INSECTS 
The most important above-ground insects are chinch bugs, sod webworms, cutworms and 
ants. 
CONTROL—Use either chlordane or DDT. Chlordane is quicker but the DDT gives a long 
residual action. For chinch bugs, use 24% lbs. of 5% Chlordane; or 5 ozs. of 40% Chlordane 
Wettable Powder in water; or 2% lbs. of 10% DDT Dust; or 5 ozs. of 75% DDT Wettable 
Powder in water per 1000 square feet. For sod webworm and cutworms, use half the 
quantity of chlordane or DDT recommended for chinch bug. Repeat applications may be 
necessary for these insects. To control ants in lawns, apply 2¥% lbs. of 5% Chlordane Dust 
or 5 ozs. of 40% Chlordane Wettable Powder in water per 1000 square feet. Repeat as 
necessary. 
DISEASE 
Brown Patch appears suddenly as discolored areas with a dark ring at the border where 
the organism is still active. The patches may vary from small spots to areas several feet 
in diameter. Dollar Spot appears as clearly defined bleached brown areas of dead grass, 
seldom larger than a silver dollar. When numerous, they destroy large areas. 
CONTROL—A preventive schedule consists of spraying with Tersan 75 every 7 to 10 days 
at 1 lb. to 9000 square feet under ordinary conditions, or 2 lbs. to 9000 square feet when 
disease conditions are severe. Periods of high temperatures (80°F.) and high humidity are 
particularly conducive to Brown Patch infection. Dollar Spot usually is more prevalent dur- 
ing low temperatures as in late spring or early fall. If a preventive schedule is not practiced, 
then the lawn should be observed closély and at the first indications of disease spray 
immediately with 2 lbs. of Tersan 75 per 9000 square feet. Repeat at 7 to 10 day intervals 
to prevent its further spread. Tersan 75 is best applied with a power sprayer at 200-300 
pounds pressure, using 75 gallons of water per 9000 square feet. If a sprinkler is used, 
apply 150 gallons of water per 9000 square feet and agitate well. 
WEEDS 
One of the most common weeds that appears in lawns is the broad-leaved type. 
CONTROL—Apply one teaspoon of G.L.F. Weed Killer MCP in one quart of water per 
100 square feet. Make this application two days after mowing, when weeds are young 
and growing vigorously. G.L.F. Weed Killer MCP is particularly desirable on lawns con- 
taining clover because it is less toxic than 2, 4-D.
