AN INTRODUCTION TO THE INSECTICIDE AND FUNGICIDE SECTION 
OF THE KILGORE SEED COMPANY CATALOG 

The extremely rapid development and use of a wide 
variety of new insecticides and fungicides together 
with the complicated chemical names and the num- 
erous trade designations have often completely con- 
fused the ultimate user. Conditions have reached 
the point, where a grower has the opportunity, or 
rather the task to choose any one of a fairly large 
number of compounds, all of which may be recom- 
mended for the particular pest he happens to be 
concerned about. 
So far, there is no best insecticide for all purposes, 
as of course the efficiency of a compound, the type 
of crop, the stage of growth of the crop, the material 
application cost per acre, weather conditions, the 
possible toxicity to plants as well as human beings 
and warm-blooded animals play an important role 
when trying to judge the suitability of any com- 
pound for any particular purpose. However, thanks 
to the many new insecticidal products now availa- 
ble, it is possible to logically select an insecticide, 
which will best suit the grower’s specific problem. 
This page of the catalog is designed to indicate the 
necessary procedure for the accomplishment of this 
aim as simple as possible. 
In the foregoing, it was indicated that a number of 
factors must be considered in order to determine a 
specific recommendation. For a practical solution 
of this task, the following table showing the princi- 
pal influencing factors as well as their respective 
ratings is submitted. 

TABLE OF RATINGS OF FACTORS INVOLVED IN THE 
USE OF INSECTICIDAL COMPOUNDS 

CONTROL FACTOR: 
1—Excellent. 
2—Good. 
3—Fair. 
4—Variable* (From Excellent to Fair). 
* Depending upon weather conditions. 
Note: A + affixed to the numerical rating of a ma- 
terial indicates that it is also effective against a 
wide variety of other insects. 
SAFETY FACTOR: 
I—No toxicity or residue problem involved. 
2—Toxicity or residue problem negligible. 
3—'Toxic to humans and warm-blooded animals, but 
no residue problem involved. 
4—'Toxic to humans and warm-blooded animals and 
possible residue problem. 
5—Highly toxic to humans and warm-blooded ani- 
mals as well as probable residue problem. Appli- 
cators should observe caution as indicated. on 
labels affixed to items in this group. 
6—Toxic to cucumbers, squash and melons. 
7—May impart objectionable odor or flavor to edi- 
ble portions of crops, especially potatoes and/or 
other tuber and root crops. 
ECONOMIC FACTOR: 
1—$0.50 to $2.00 per acre. 
2—$2.00 to $3.00 per acre. 
3—$3.00 to $4.00 per acre. 
4—$4.00 to $5.00 per acre. 
5—$5.00 to $6.00 per acre. 
6—$6.00 to $7.00 per acre. 
7—$7.00 and higher per acre. 
Note: Dust costs calculated at 30 lbs. per acre (single 
application). Spray costs calculated at 125 gallons 
per acre (single application). 
The foregoing table is intended to be used in con- 
nection with the insecticidal recommendations for 
individual insects shown on pages 57 to 62. To illus- 
trate the procedure to be followed, let us assume 
that we are troubled with aphids infesting the fol- 
lowing crops: 
1—Cucumbers. 
2—Tomatoes—not bearing mature fruit. 
3—Tomatoes—bearing some fruit ready to pick. 
4—Potatoes. 
We will first refer to the Chart “Insecticide and 
Fungicide Recommendations” (pages 54 to 56) and 
look up the particular crop that we are interested 
in. We will next locate the line which lists “Aphids.” 
The second column refers us to page 57 of the cata- 
log, where we will find a description of the insect as 
well as numerous recommendations for both dust- 
ing and spraying purposes. In the case of aphids, 
seven dust and seven spray recommendations are 
listed. On the right of the listings, we find three 
columns headed up as follows: 
C.F. (Control Factor) 
S.F. (Safety Factor) 
E.F. (Economic Factor) 
In choosing the best insecticide for a particular pur- 
pose, all of the factors indicated should be scrutin- 
ized. The S.F. (Safety Factor) should be considered 
first of all. In examining this column we find that 
any products with a rating of “6” are automatically 
eliminated, as the “Table of Ratings Factors” shown 
on this page shows that materials rated as “6’’ may 
prove toxic to cucurbits (cucumbers, squash, mel- 
ons, etc.) So we would not want to use Kilhex Dust 
114%, Kilphene-10 Dust, Alltox Wettable No. 400, 
Gamtox Wettable and neither of the DDT Emulsion 
or Wettable. This leaves us with the following: 
Ce Ee S Eo 
Black Leaf 10 Dust 4 3 3 
Kilchlor Dust-5% ae a 
Kilgam Dust-114% las <4 
Nicotine Dust-4% Activated + 3 5 
Rotenone Dust-1% 2 Z 4 
Black Leaf 40 4 3 + 
Isotox-Wettable No. 250 J+ 4,7 3
