POINTS TO KEEP IN MIND. 
1. Sprays are preventives, not cures. 
2. Early spraying is the key to success in the use of fungicides. 
3. Combined fungicides and insecticides, the copper-arsenic solutions, 
are recommended whenever applicable. 
4. It is too late to begin making applications of fungicides after the dis- 
ease has made its appearance. 
5. Only with a nozzle throwing fine spray can fungicides and insecticides 
be properly applied. 
6. Agitators must be used to keep solutions thoroughly mixed if satisfac- 
tory results are to be obtained. 
7. The number of applications necessary cannot be stated. It depends 
upon the weather and the extent of the disease. 
8. Great care must be exercised to have the mixture properly made and 
applied to prevent serious injury to foliage. 
9. Diseased portions of trees affected with some fungi must be removed 
and the rubbish burned. In “canker” and “gummosis” remove the affected 
parts, wash with copper sulphate, and bind. 
10. Spraying must be done in a thorough manner, every leaf must be 
reached, vigilance in repeating the treatment must be observed, and spraying 
must not be delayed until diseases have appeared to a damaging extent.
