FIG. 8. APPLE BLOSSOM BUDS. This shows 

 the stage of development of the buds when the 

 "pink" or "cluster" application is usually made. 



FIG/ro. APPLE BLOSSOM BUDS. If the 

 i buds remain in this stage for several days 

 because of cold weather and conditions are 

 favorable for scab development, an extra 

 application will probably be profitable. It 

 should be followed by the regular cluster ap- 

 plication.
