.could time his spraying perfectly. l)iit this being impossible the time has 

 been put by Prof. R. E. Smith and his coworkers at from the first of 

 October till the middle of December for the first spraying, and about 

 the middle of February, or just before the buds open, for the second 

 spraying. Practice seems to have shown that the first spraying may be 

 Bordeaux mixture about 5-5-50 and the second spraying lime-sulphur 



solution. 



Methods of Prevention Vary. 



The above description of the means of prevention illustrates only a 

 few of the different methods to be used against fungous attack and 

 points out the fact that while certain general rules may be applied for 

 fighting certain classes of fungi, each tree disease, just as each human 

 disease, must be studied and experimented with until a method best 

 adapted to preventing that particular one is found. What wall be 

 highly successful in preventing one fungous disease may be an entire 

 failure when applied to a different one. 



In conclusion, the ideal line of prevention for fungous attack should 

 begin at or before the seed is planted or the bud is chosen for propaga- 

 tion, with the thought of selecting varieties of strains naturally resistant 

 to serious diseases. Then the cut surfaces or chance wounds should be 

 protected and allowed to heal smoothly and without decay, the tree 

 should be surrounded with the best conditions for growth, and therefore 

 resistance to many fungi, and when all these fail and attack comes, as in 

 case of special or new diseases, then to cover the parts with spraying 

 solution to keep the spores from germinating upon the surface or to put 

 up barriers when possible against them. The easier and less expensive 

 X-revention, rather than the more difficult and more costly cure, is what 

 we should strive for in the control of fungous diseases.
