say. the art, of sjirayiug. to become a regular and necessary 

 part of the fruit growers' farm operations. We still find an 

 occasional man who claims that he is able to grow profitable 

 crops of fancy fruit without spraying, but even such t-laim^ 

 are now few and far between. Thousands of pages have 

 been written and still more words spoken on the spraying 

 of fruit trees; yet the up-to-date fruit grower is still looking 

 for something new. You will not find anything very new 

 in my talk this morning, but perhaps it will be possible for 

 me to present some of the old points in a way that will be of 

 some practical value, or at least start a discussion. Your 

 president and secretary have both impressed upon me their 

 desire for a practical spraying tallx. It is fortunate that 

 such is the case, as it would be impossible for me to talk from 

 tlie technical viewpoint of the trained entomologist or plant 

 j'athologist. Therefore, my talk this morning will be from 

 the standpoint of the practical fruit grower. 



First let us consider the essentials for success in spray- 

 ing. Is it essential that the fruit grower have a thorough 

 knowledge of the details involved in the preparation of a 

 large number of spraj' mixtures? Is it essential that he 

 know the chemical analysis of every spray mixture that he 

 finds it necessary to use in his orchard? Is it essential that 

 he know the exact life history and habits of every insect 

 that may be fourd in orchards? Such points are quite es- 

 sential to the scientific investigator, but not absolutely 

 essential to success in practical spraying A fruit growler, 

 equipped with a clear understanding of the preparation, and 

 practical range of usefulness, of three or four standard 

 spray mixtures; with an efficient outfit, and with a deter- 

 mination to do thorough work, will be more successful than 

 the man who insists on experimenting w4th every new prep- 

 aration that comes along regardless of actual experience. 

 We might say that the essentials for successful results in 

 spraying are three: first, thoroughness of application; sec- 

 ond, proper materials; third, applications made at the right 

 time.
