1978 Insect Pest Management Guide

COMMERCIAL VEGETABLE CROPS
And GREENHOUSE VEGETABLES

You must be certified as a pesticide applicator to use "restricted use" pesticides.
See your county extension adviser for information.

Commercial vegetable gardeners find it impossible to pro-
duce vegetables profitably unless they control insects at
maximum efficiency and minimum cost. The housewife of
today will not accept unsightly wormy vegetables; not only
are wormy fruits and vegetables unappetizing but the
waste from trimming increases food costs. Thus the com-
mercial vegetable gardener must produce a quality product
that is acceptable and safe to the consumer. Careful use
of the right insecticides will enable him to do this.

Insect pest management programs, which include the
wise selection of cultural, mechanical, biological, and
chemical methods, are suggested for the major insect pests
of vegetable crops and greenhouses. But, insecticides are
still the most efficient means of managing most insects.

This suggested insecticide guide has been prepared for
use by Illinois commercial vegetable farmers; it is not for
home gardeners, who should use only those insecticides
that are extremely safe to handle, apply, and store. Fur-
thermore, the commercial vegetable gardener must use a
wider variety of insecticides than the home gardener in
order to obtain maximum insect control at the least cost.

In using insecticides, read the label and carefully follow
the instructions. Do not exceed maximum rates suggested;
observe carefully the interval between application and har-
vest, and apply only to crops for which use has been ap-
proved. Make a record of the product used, the trade name,
the percentage content of the insecticide, the dilution, the
rate of application per acre, and the dates of application.

Some of the insecticides suggested here can be poison-
ous to the applicator. In using them, the commercial grower
is expected to use precautions to protect himself, his work-
ers, and his family from undue or needless exposure.

In using this guide, always refer to the table on the next
page, which lists the limitations and restrictions on use.
These limitations apply to the vegetables as human food.
If you use any portion of a vegetable for livestock food
(tops, stalks, etc.) refer to the label for instructions as to
the interval required between application and feeding.

The chemical names used in these tables may be un-
familiar to you. These names are the common coined
chemical names and as such are not capitalized. Trade
names are capitalized. In the table of limitations the com-
mon names are listed first. If the trade name is more com-
monly used, it is listed in parentheses following the
common name. Throughout the tables of suggestions, how-
ever, the common name is used if there is one. In case of
question, refer to the table of limitations.

These suggestions are subject to change without notifi-
cation during the growing season.

Requested label clearances for a few uses of insecti-
cides, carriers, and solvents are uncertain for 1978, since
many requests have not been officially cleared. Anticipating
needed changes in labeling, we began modifying these sug-
gested uses a few years ago. Be sure to check with your
county extension adviser if you are in doubt about the
insecticide you plan to use. We will make announcements
of label changes through the newsletters and news media
to keep you up to date.

Insecticides are being classified for general use or re-
stricted use by the U.S. Environmental Protection Agency.
A person wishing to use an insecticide classified for re-
stricted use must be certified as a private or commercial
pesticide applicator by the Illinois Department of Agri-
culture. Contact your county extension adviser in agricul-
ture for details on this program. Only a few insecticides
have been classified at this time. More will be classified
later. Insecticides bearing a restricted-use classification are
identified by an asterisk (*) in this circular.

Suggestions for use of insecticides effective from a
practical standpoint are based on available data. Soil tex-
tures, pH of the soil, rainfall, slope of the field, wind
velocity at planting, method and accuracy of application,
and other unpredictable factors affect efficiency.

nois Natural History Survey.

1 Root crops such as radishes, turnips, carrots, horseradish,
potatoes, and sugar beets should not be grown in soil where aldrin,
dieldrin, or heptachlor was applied as a soil insecticide the pre-
ceding year.

* Use only by professional applicators or commercial gardeners.
'Trade names are Biotrol, Dipel, and Thuricide.

4 Only apply insecticide late in the day after blossoms have
closed to reduce bee kill.

A. If tops or stover is to be used as feed.

B. Not more than twice per season.

C. Soil applications at planting time only.

D. Do not use on green onion crop.

E. Do not use tops for feed or food.

F. Not more than three times per season.

G. Not after edible portions or heads begin to form.

Workers must wear protective clothing if they enter treated
fields before time intervals at right. They must also wear pro-
tective clothing for all other insecticides applied if spray has
not dried or dust has not settled.

FOR YOUR PROTECTION

Always handle insecticides with respect. The persons
most likely to suffer ill effects from insecticides are the
applicator and his family. Accidents and careless, needless
overexposure can be avoided. Here are a few easy rules
that if followed will prevent most insecticide accidents:

1. Wear rubber gloves when handling insecticide con-
centrates.

2. Do not smoke while handling or using insecticides.

3. Keep your face turned to one side when opening in-
secticide containers.

4. Leave unused insecticides in their original containers
with the labels on them.

5. Store insecticides out of reach of children, irrespon-
sible persons, or animals; store preferably in a locked
cabinet.

6. Triple-rinse and bury or burn all empty insecticide
containers or take to an approved sanitary landfill.

7. Do not put the water-supply hose directly into the
spray tank.

8. Do not blow out clogged nozzles or spray lines with
your mouth.

9. Wash with soap and water exposed parts of body
and clothes contaminated with insecticide.

10. Do not leave puddles of spray on impervious
surfaces.

11. Do not apply to fish-bearing or other water supplies.

12. Do not apply insecticides, except in an emergency,
to areas with abundant wildlife or to blossoming crops
visited by bees. Avoid drift onto blossoming crops or onto
bee hives.

13. Do not apply insecticides near dug wells or cisterns.
