226 REpoRT OF THE HorTICULTURAL DEPARTMENT OF THE 
“Last season our apple foliage was spotted and burned and much of it 
dropped. The fruit was russeted, malformed and reduced in size. In 1904 
we sprayed with the same formula with excellent results to the fruit and 
with but slight injury to foliage. We used 6 pounds of copper sulphate to 
50 gallons of water and lime sufficient to satisfy the ferrocyanide test. For 
an arsenite, 55 ounces of acetate of lead and 20 ounces of arsenite of soda 
to 50 gallons of the bordeaux. Since we have used a power sprayer and 
‘have given the foliage a thorough drenching from above and below, we 
have had more spray injury than when we used a hand pump and only 
sprayed from above. Moisture and excessive heat closely following spray- 
ing seemed to give favoring conditions for the injury. Some years we have 
had excellent results without apparent injury, while in other seasons our 
spraying has either injured the fruit or foliage, or both, and without any 
apparent reason.”— C. E. & E. H. Munrt, Leroy. 
It is to be noted that several growers, as above, state that bor- 
deaux injury has come with the advent of power sprayers and | 
thorough spraying whereby more of the spraying mixture is used. 
“My fruit was not injured to any great extent the past season but some 
trees showed considerable injury to the foliage. I have had more or less 
trouble with this injury ever since we have followed the practice of spraying 
thoroughly. We used 4 pounds of copper sulphate and double that quantity 
of lime to so gallons of water with white arsenic and sal soda. Do not 
know which ingredient does the harm but think that spraying during wet 
time gives conditions under which the injury is liable to occur.”— W. E. 
PALMER, Brockport. 
According to Mr. Palmer, more than doubling the amount of 
lime necessary does not prevent the injury. 
“The past season my apples were badly russeted and from 15 to 25 per 
ct. of foliage dropped. On some trees 50 per ct. of the foliage dropped. 
In 1903 my fruft was badly russeted but there was no injury to the foliage. 
In 1004 the foliage was most susceptible to the injury, although the fruit 
was injured some. I suffered most damage in 1905. I use 8 pounds of 
copper sulphate and twice as much lime as the ferrocyanide test requires, to 
100 gallons of water. To bordeaux so prepared, I add two-thirds of a 
pound of arsenite of soda. I think the injury is due to the copper sulphate. 
In our orchards where the trees have been sprayed most thoroughly, the 
injury has been greatest. I have thought that the injury was due to weather 
conditions but the varying conditions of the past three years have upset my 
theories in this regard. King has suffered most after which, in order named, 
come Baldwin and Greening. Another year we shall use a smaller amount 
ef copper sulphate.”— F. A. SALispury, Phelps. 
Attention is called to the great excess of lime used by Mr. 
Salisbury in ‘spite of which the injury occurs.
