Things to Do and Observe 



1. To learn to recognize the symptoms of the "various diseases oj 

 garden "vegetables. Watch for the earliest appearance of a plant 

 disease. If at any time a plant looks as if it were diseased, try 

 to learn what disease it is, either by referring to a garden book 

 or by asking an experienced gardener ; or, if you cannot find out 

 in any other way, send specimens of diseased plants to the state 

 agricultural experiment station for identification, and ask for 

 information. In this way you will get into the habit of watch- 

 ing for the appearance of disease in your plants and you will 

 know just what to do as soon as you recognize the disease. 



2. To learn how to control plant diseases. Secure bulletins 

 from your state department of agriculture on the diseases of 

 garden vegetables and their control. Consult the local dealer as 

 to the kind of sprayers and fungicides he sells. Inquire among 

 gardeners as to which of these are most effective.
