 far as simplicity and effectiveness are concerned, I do not believe 

 anything can beat that simple outfit." 



Mr. Ives: "We use five nozzles instead of four." 

 Dr. SturgiS: "This is fitted w^ith a thirty-foot length of 

 hose, and is very convenient and handy in that respect, because 

 if the operator wishes to go ahead a little faster he can do so. 

 He does not have to vv^ait for a few^ moments while the cart is 

 coming up, but he can go right on spraying, as he has the 

 apparatus with him. That is not possible with the fixed pipe." 



THE SPRAYING OF PEACH TREES 



BY DR. W. C. STURGIS, Mycologist, Connecticut Experiment Station, New Haven 



It will not be advisable for me to attempt to give in detail a 

 full account of this subject, first, because the main feature of 

 this session is a lecture upon some diseases of fruit trees, and 

 secondly because the experiments concerning the results of 

 which I have been asked to speak briefly, are described fully in 

 the Experiment Station Report for the past season. 



What led to a careful series of experiments on spraying 

 peach trees was the general and well-founded reluctance on the 

 part of Connecticut peach -growers to submit their trees to the 

 action of a fungicide which had proved destructive to foliage. 

 Whatever were the facts regarding this matter observed else- 

 where, it had become a settled conviction that, for some 

 unexplained reason, peaches could not be sprayed with safety in 

 this state, at least, with Bordeaux mixture. 



In order to give this matter a thorough test, a number of 

 trees, comprising several varieties, were selected in two large 

 peach orchards and, beginning early in the season, they were 

 sprayed with Bordeaux mixture, in which the quantity of the 

 respective ingredients varied from one to five pounds of copper 

 sulphate, and from two to five pounds of lime, in fifty gallons of 

 water; with a Bordeaux mixture made with soda in place of 

 lime, with the ammonia solution of copper carbonate, and with 

 potassium sulphide in solution (i lb. to 50 gals.). Late in the 

 season two forms of copper acetate in solution were tried. In 

 all, eight different fungicides, made and applied in the most
