JUST 
ONE 
PRODUCT 
.. BUT 
SO MANY 
USES 

















When diluted according to di- 
rections for spraying, Black 
Leaf 40 becomes a volatile in- 
secticide. It kills insects both 
by contact (wetting) and by 
fumes. This double-effect fur- 
nishes increased efficiency and 
quick killing power. 
The spray gradually ‘‘fumes off” 
or evaporates from the foliage 
and fruit. Efficiency, rapidity of 
action, and its many uses make 
Black Leaf 40 a logical insecti- 
cide to rely upon. 
Three Decades 
of Effective Service 
Recommended by Colleges and 
Experiment Stations for 30 
years, Black Leaf 40 has estab- 
lished a remarkable record.
