CONTROL OF CHINCH BUGS ON LAWNS

E. G. Kelsheimer


The chinch bug is a sucking insect and its damage to St. Augustine grass is

especially noticeable during dry weather. The injury to lawn appears as yellow or

brown areas usually first along driveway, walks and curbing. Disease, nematodes and

physiological disturbances may cause this discoloration and death of grass. Many

tons of insecticides have been applied to areas that did not have chinch bugs.

The best way to find the bugs is to float them out of the grass with water.

To do this sink a tin can into the grass far enough to hold water. Use a stiff-sided

metal can with a sharp edge. Press the can down into the turf with a circular motion.

The edge of the can must be sharp and plenty of weight must be applied to it for St.

Augustine grass runners are tough. Fill the can with water and wait for a few minutes

to observe any insects that float to the surface. After satisfying yourself that

chinch bugs are present, proceed to treat your lawn immediately. You will thereby

save yourself a lot of work and expense later on.

You will have much more trouble from chinch bugs in a thick-matted turf than

in now lawns or unfertilized lawns. It will be necessary not only to use more insect

cide but also to apply it more frequently on these deep turfs.

There are several good chinch bug killers that the homeowner can purchase

locally.

DDT: DDT is a good, dry weather insecticide. Some people have good results on a

thin-turfed lawn with fresh five percent or ton percent DDT dust, applied at the

rate of one pound per 100 square feet. DDT spray can be applied at the rate of one

and one-half ounces of 50 percent DDT wettable powder to 10 gallons of water for 100

square feet of lawn. The lawn should be watered after the spray application.

C1HLORDMA : Chlordane has been most widely used on turf in Florida. It is very effec-

tive against chinch bugs when used correctly and at the proper time. Many people be-

lieve that chlordane is not.offective, usually because they used the wrong formulation







or did not apply it correctly. Do not use a 5 pc0oent dhiordane dust or a ferti-

lizer containing chlordane on a lawn fof chinch bug control. These formulations

are very good against webwoims, ar'iywoim, hhtd, cutworms and mole crickets but

not against chinch bugs.

Chlordane is available in other formulations, including emulsifiable concen-

trates, wettable powders and granules. Very little of the wettable powder is used

for chinch bug control, but the emulsions and granules are now used extensively and

are giving good control when properly applied. Chlordane emulsion can be purchased

in two concentrations. The formulation contaiining 70 to 80 percent chlordane should

be applied at the rate of one-half ounce to 100 square feet with sufficient water to

wet down thoroughly. The 47 percent emulsion is applied under the same conditions

but an ounce to 100 square feet should be used.

Chlordane in a 5 percent granular form is especially well adapted for small

areas and spot treatments. The label should show that the material has been prepared

from an emulsion. Apply the granules at the rnto of 1 pound to 100 square feet dur-

ing the hottest part of the day. Water the treated area thoroughly that evening or

the following morning, since chlordane is ineffective if used under dry conditions.

Chlordane is not a fast killer. It may be necessary to repeat the application in 7

to 10 days to kill hatching nymphs and insects missed at :.he firstt ppication.

DIELDRIN: Another insecticide that has received approval for use on lawns is diel-

drin. Dioldrin is slow in killing but has a long residual effect. One application

should be sufficient if properly applied, but a second application is often mado bo-

cause of its slow action. The concentration of the granular formulation should be

2.0 percent of dieldrin. This material is applied at the rate of 1 pound to 100

square feet. The 15 percent emulsion is applied at the rate of 2 ounces per 100

square feet. Add sufficient moisture to effectively wet down the lawn.

PARATHION: The question is often asked concerning the use of parathion on the lawn.

At the present time there is no recommendation for the use of parathion by the home-

owner. However, parathion is used effectively by commercial operators who know how

to use it safely and have proper equipment, sudh as face masks, protective clothing

-2-












and gloves. Wo wish to point out a few precautions to those commercial operator,:

Do not apply parathion on a windy day. Keep children and pots away while the opora-

tor is at work. Children and pots must stay off treated promises for an hour or at

least until the grass is dry.

Chinch bugs can be controlled if proper measures are used in time. No

amount of pesticide will bring back a lawn practically dead from neglect. For those

who intend to leave for the summer, either make arrangements for some competent yard

man to take care of your premises or give your lawn an overall treatment before you

leave.

Completely surround your promises with a 3 foot barrier of your preferred

insecticide to protect your lawn against the invasions of chinch bugs from untreated

or neglected areas surrounding you. This barrier is an extra treatment of the same

material. Chinch bugs are usually very weak fliers, so it is necessary for them to

crawl or be carried from one area to another.

One question frequently asked is whether to treat only the affected spots

or to treat the whole lawn area. Spot treatments are effective for homeowners who

can watch their lawns fr-m day to day. Complete coverage of the lawn with the insec-

ticide is recommended to the commercial operators and to absentee owners.
