Insecticides and Fungicides 
Letherman’s 


MATERIALS FOR CROP PROTECTION 
To control Insects and Plant Diseases on Vegetables—Flowers—Roses—Fruits—Ornamentals Shrubs— 
Trees and Lawns. 
Letherman’s policy is to have not only the seeds, plants and bulbs to take the first step to good crops, 
but to have for you the very best controls for any pest that might threaten those crops. 
We are members of the Ohio Pesticide Institute and adhere very closely to the recommendations and 
information given to us by the Ohio Experiment Station, the USDA and Technical Experts of the country’s 
largest and most forward looking Chemical Manufacturers.
