Mr. Fritz Bahr Says: 
HIGHLAND PARK GREENHOUSES 
Dec. 1, 1936. 
“We wouldn’t thin\ of replacing a bench or groundbed, 
no matter what it consists of, after the soil has been worked 
over, without applying a good dose of To'hfa'Cide and lightly 
wor\ing the same into the surface. We have found this 
insecticide by far the most efficient weapon to get rid of and 
\eep under control sowbugs and many other insect pests 
usually found in soil made use of under glass.
