SPRAYING GUIDE FOR GARDEN AND 
LAWN PLANTS 
It is not our intention to attempt a complete list of all insects and diseases attacking plants of the garden 
and lawn. We are listing only the more common ones that every amateur gardener must combat. 
The control offered for each is the one we have found to be the most economical and effective, but we 
cannot guarantee results, for method of application, weather conditions, etc., always produce varying results.
