Our experimental work in the fruit department the past season has 
been smal]. The apple crop was substantially a failure. The pear, 
peach, plum and cherry trees yielded a fair crop of fruit, but we found 
no opportunity for experimental work upon these. The disease known 
as ‘‘ curl-leaf” attacked the foliage of our peach trees last spring, as 
it did in the spring of 1882. We made inquiry as to the nature of 
this disease of Prof. J. Henry Comstock, the entomologist of Cornell 
University, which elicited the following letters of information: 
‘*'The peach trees are suffering from the disease known as “‘ curl- 
leaf,” a common disease, which is sometimes very destructive. This 
is especially the case in California. I have not seen so much of it in 
the Kast as I have in that State. So far as I know, nothing is known 
of the cause or nature of the disease. 
‘*When plant lice (aphidae) attack peach leaves, they cause a 
similar appearance, but ‘‘curl-leaf” strictly speaking, is independent 
of the presence of any insect.” 
This letter published in the Station Bulletin No. 48 brought out 
the foliowing letter from Dr. B. D. Halsted of New York city, who 
is especially skilled in that branch of science which includes the injuri- 
ous fungi: 
“« May I add to the information on the peach curl given in the Bul- 
letin for June 16th? ‘This injurious deformity of the peach leaves 
has been ascribed to plant lice and other insects, but it is now known 
to be caused by a minute fungus known to science as Zaphrina de- 
formans. This minute parasitic plant makes its appearance in early 
spring and causes the foliage to twist and curl out of its natural 
shape. ‘lhe fungus is not distantly related to the one which causes 
the black knot of plum and cherry trees, and, so far as 1 know, the 
same remedy is the only one used, viz., to remove and burn all of the 
affected parts as soon as they appear. It is best to cut off the young 
twigs bearing the ‘‘ curled ” leaves, and this can be done quite rapidly. 
Care should be taken to burn all the parts removed to prevent the 
ripening of spores in the infested leaves.
