attributed to some other factor. This again emphasizes the fact that 

 in spraying for Leaf Curl the character of the fungicide is too often 

 over-emphasized. It is the least important of all the factors involved 

 in the successful control of this disease.

Out of a total of 71 reports received in 1908, 55 (78%) report good 

 results from spraying, regardless of methods or material used. Twelve 

 of these (16%) report complete control, and 7 fairly good. This gives 

 a total of 87% of the reports ranging from good to fair, while only 9 

 (12%) reported poor results. Three of these stated that no benefit 

 whatever had been derived from the treatment. 



For 1909 a small number of reports were received: 11 report good 

 results (including 5 getting complete control), 2 poor results, and i no 

 success. 



From the above summaries of the reports of growers themselves 

 during two severe Leaf-Curl seasons, it is safe to say that spraying 

 for Peach Leaf Curl is a successful orchard practice among the peach 

 growers of this State. Of all the factors involved, the man who does 

 the spraying is the most important, and to him is to be properly laid, 

 in most cases, such failures as result. No peach grower who grows 

 varieties susceptible to Curl can afford to neglect to spray. 



It has also been clearly demonstrated that the application to be 

 effective must be given early, before the buds are too far advanced. 

 There is much discussion at present as to which is the most effective 

 spray to use. Bordeaux mixture and lime-sulfur solution have both 

 been used successfully.
