At this time the degree of injury, as noted by the eye, stood 
about as at the close of the experiment. 
In the daily observations it was noted from the start to the 
finish of the experiment that the injury was greater on the 
trees sprayed during rain than on those sprayed during dry 
weather; with both applications of the copper compound con- 
siderable injury appeared immediately on the trees sprayed in 
rain; on those not so sprayed, only traces of injury were found 
until rain had fallen. The inevitable conclusion to be drawn 
from observation, quite aside from the results to be given later, 
is, that wet weather favors the production of the imjury. 
The injury on fruit was more noticeable in July than at any 
other time. After July the fruit seemed to outgrow and throw 
off much of the russeting. This was the case in our experi- 
mental plats, but much more so in other orchards that came 
under my observation. On the fifteenth of June the writer was 
called to Albion, New York, to visit a number of orchards in 
which it was supposed some new fungus was destroying the 
fruit ;—the trouble turned out to be the bordeaux injury. About 
twenty orchards were visited, some of them showing the worst 
cases of bordeaux injury I have ever seen. Many fruits were 
covered with russet; some had gaping cracks; much of the fruit 
was malformed; and the foliage of all was badly injured. A 
later visit on the twentieth of July showed that the fruit was 
in much better condition than at the first visit. There was less 
russeting; many of the cracks had healed over and the malforma- 
tions were less pronounced. Reports from the damaged orchards 
at harvest time were to the effect that the injury was even less 
apparent than at the last visit; and that comparatively little of 
the fruit was wholly unmarketable, the loss being in the lessened 
yield through reduced size. 
Unfortunately there was comparatively little injury to foliage 
in our experiment plats; an unexplainable condition, for in the 
State at large there was much injury to foliage. For this reason 
the results given have to do chiefly with injury to the fruit. 
Manner of development of bordeaux injury on fruit.— From 
its appearance until the crop was harvested, studies were made 
of the injury as it developed. A brief summary of these studies 
is made here. | |
