PESTICIDE SECTION 
(Insecticides, Fungicides, Fumigants, Vermicides, Weed Killers, Spreaders, Stickers, 
Emulsifiers—Pages 50 to 66.) 
The sources of information and recommendations in connection with insect pests and diseases given in this 
catalog are, the State Experiment Stations, The Kilgore Seed Company Laboratory, our technically trained 
field men, and many members of our store personnel who have had years of close contact with agricultural 
problems. 
Every attempt has been made to provide such information in a plain and simple form for the benefit of 
our growers. As, however, constant changes are taking place in the field of pesticidal problems because 
of new insect pests and diseases and the introduction of new pesticides, it is impossible to keep an annual 
catalog strictly up-to-date. We therefore invite you to remain in personal contact with our field and store 
men as much as possible. They will be glad to assist you whenever you are facing new problems.

As truck farming becomes more extensive in Florida we 
naturally are going to have more diseases and insects to com- 
bat, which have already become a major factor in producing 
a crop. Fungicides and insecticides are just as necessary in 
producing a good crop as fertilizers, etc. There are many 
factors involved in the use of fungicides and insecticides as 
to the results obtained, such as the proper fungicides and in- 
secticides for the control of different diseases and insects, the 
time and method of application. One cannot expect satisfac- 
tory control with poor or wrongly timed applications. Too 
often the grower (especially with diseases) waits until the 
disease or insect has too much of a start before spraying or 
dusting. This usually is more expensive than starting off with 
a regular spray or dust program and keeping it up to prevent 
diseases and insects. You not only have to use as much spray 
or dust to get control, you also suffer crop damage. It is much 
cheaper where insects and diseases are both to be contended 
with to use a combination spray or dust, as one application 
will do both jobs. Most fungicides and insecticides are com- 
patible and can be used together in a spray. We manufacture 
most all the combination fungicide dusts generally used. Only 
a few of the combinations are listed in this catalog. If you do 
not find the combination listed you want, write The Kilgore 
Seed Company, Plant City, Fla., or call at any of the Kilgore 
stores. Our fungicide and insecticide materials for making 
Sprays are the latest and the highest quality that can be ob- 
tained. Our dust is mixed in our own plant which insures 
you getting freshly mixed dust and in the best mechanical 
condition. 
SANITATION 
The practice of sanitation is of such vital importance, that no 
grower can afford to ignore the subject. Yet, in many cases, 
serious losses result from a complete neglect of a few simple 
rules. Diseases will spread readily from sick to healthy plants 
by various means, depending upon the nature of the disease. 
Spores of many species of fungi are air or wind borne, while 
others may be scattered over fields in water, due to rain or 
irrigation. Insects play an important part in the dissemination 
of diseases, particularly those of the sucking type, such as 
aphids, thrips, etc. Certain cultural operations, as prunning, 
picking, transplanting, etc., are greatly responsible for the 
scattering of diseases, especially those caused by bacteria and 
viruses, mosaic being a specific example of the latter. 
Considering the methods of dissemination mentioned, it be- 
comes obvious that the source of the disease should be de- 
stroyed, if at all possible. Affected plants, as well as dropped, 
decaying fruit, should be removed from the field and burned. 
Cultivation should be clean and frequent. Mechanical injury 
of plants by plowing, spraying or picking operations should 
be avoided as much as possible. Crop rotation is essential, pro- 
vided that no other crop affected by the responsible diseases 
is grown for several years. This method often proves cheaper 
than an attempt to control the disease chemically. As weeds 
serve as host plants to many insects, which may be carrier of 
fungi, viruses, etc., the necessity of their eradication certainly 
becomes evident. Whenever practical, soil moisture should be 
kept fairly constant. Corrective measure should be adopted 
where soils are either too acid or too alkaline. 
MOSAIC 
Mosaic disease is caused by organisms (virus) in the sap of the 
affected plants. The viruses, as infectious principles, may be 
transmitted from diseased to healthy plants in various ways. 
Insects undoubtedly play an important part in the trans- 
mission of the disease, although it may be spread by other 
means, such as pruning operations, bruising of plants by 
workers or mechanical equipment, picking fruit, etc. 
‘The symptoms of mosaic vary slightly in different plants, but 
in general, certain broad characteristic indications can be 
noted in most all infected plant types. There is usually a 
stunting or dwarfing of the plants, with accompanying pattern 
of light-yellowish areas merging with green patches, giving 
them a “mottled” effect. Usually there is a roughening of the 
surface, producing in some cases a warty appearance. Edges 
of leaves often cup downward. The fruit also may be mottled 
and warted. 
Mosaic has become a very costly and destructive disease on 
many crops, especially peppers, tomatoes, cucumbers and 
squash. This disease apparently does not carry over in the 
soil, provided cover crops are turned under long enough to be 
decomposed before planting. The disease is carried from 
season to season in wild host plants in and around the field, 
and is transmitted to the plants in the field by insects, par- 
ticularly aphids, thrips, etc. 
Pepper and tomato seed beds should have clean cultivation 
two or three weeks before planting the seed. The seed beds 
should not be close to ditch banks or fence rows, unless the 
weeds near the beds are destroyed by weed killers or some 
other method. Smoking or the use of tobacco should not be 
permitted while working in the seed beds or handling plants. 
Tobacco mosaic has been known to be carried on tobacco. If 
plants become affected with mosaic in the seed beds do not 
set them in the field. Once the plant gets the disease there is 
no known cure. 
The State Experiment Station is working hard on virus dis- 
eases, trying to find some method of control, or resistant var- 
ieties of vegetables. If they are successful it may take several 
years, so the only recommendation that can be offered now 
is sanitation, destroying all weeds in and around the field 
possible, and the control of insects.
