MATERIALS FOR CROP PROTECTION 
To control Insects and Plant Diseases on Vegetables—Flowers—Roses—Fruits—Ornamental Shrubs—

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.
