Insecticides and Fungicides 
NIAGARA BRAND 
important 
The use of DDT in spray form or in dust mixtures 
should be limited to certain specific crops and for certain 
specific insects. DDT is a poison, and, as yet, insufficient 
work has been done to permit us to recommend its use 
on a wide program. There are two crops, however, on 
which DDT seems to be safe and effective: One of these 
is potatoes, for control of flea beetle, leaf hopper, and 
certain beetles; the other crop is cabbage, for control of 
green cabbage worm and cabbage iooper. It is also effec- 
tive against many species of green aphis on these crops, 
if used at proper strengths. We definitely do not recom- 
mend the use of DDT materials on vegetable crops, such 
as cucurbits, tomatoes, celery, etc. ... unless the grower 
has been specifically advised by the local County Agri- 
culture Experiment Staff or by some other competent 
expert in crop control measures. We definitely do not 
recommend its use on farm or home gardens, as Rote- 
none will control most insects that DDT will control, and 
will do it safely and economically. DDT, in some in- 
stances, is injurious to the set of vegetable-fruits—for 
example: Tomatoes, cucumbers.
