 thorough spraying with Bordeaux. 



Apple blotch is a disease that has become 

 very prominent in the last few years. It forms 

 splashy brown markings on the fruit, attacks 

 certain varieties more than others and winters 

 in the form of cinnamon brown cankers on the 

 smaller twigs. For several years I thought that 

 we had discovered a cure for this disease by 

 winter spraying. I still think so. The experi- 

 ment station workers in at least two states 

 think I am mistaken. Perhaps I am, but I do 

 know that in our own orchards we absolutely 

 exterminated this disease by an application of 

 commercial lime sulphur solution diluted at the 

 rate of one to five. Frank N. Wallace, State 

 Entomologist of Indiana, with whom I had the 

 opportunity of working out this new method, 

 has repeatedly controlled the disease in the 

 same way. A few other growers who have tried 

 it report varying success. Why the experiment 

 station workers have failed I do not know un- 

 less they failed to apply the material so that 

 every twig was covered. If that is done and 

 the material used at the dilution of one to five, 

 or perhaps one to four, I do not believe any one 

 need fear this disease. I certainly do not fear 

 it for I have repeatedly exterminated it in 

 blocks where it had secured a start. Further- 

 more, with this treatment the disease is con-
