IPM Monitoring & Treatment for Lawn - Landscape: 
 
 
 Treatment may be needed for problems identified 
 last year or after an  inspection.  
 
 Many problems require only thinning and pruning of damaged wood. 
 
 Other problems are not serious enough to warrant treatment. 
 
 Know what you are spraying for and when to spray. 
 
 Below are listed key problems to look for now. 
 
 Check the links on our Home Page for further information on 
 least-toxic alternatives using Integrated Pest Management (IPM). 
 
 An explanation for the symbols used below is located in our 
 pamphlet entitled "IPM Index", accessible through our home page.
