SUMMARY. 
1. In these"experiments, pear scab was successfully treated by 
dilute Bordeaux mixture containing four pounds of copper sul. 
phate to forty-five gallons of the mixture. 
2. Comparing three treatments after the buds begin to open 
and before the blossoms open with two treatments during the 
same period, it is still doubtful whether enough benefit may be 
gained from the former to justify the expense of the extra treat- 
ment. 
3. In order to treat pear scab successfully, the spraying must 
be done thoroughly and at the right season. 
4, The benefits of the treatment extend to the tree as well as 
the fruit, as shown by the increased vigor of the foliage and fruit 
on the sprayed trees when compared with the unsprayed trees. 
BrispuioGRAPHY. 
A few reference to articles on pear scab and its treatment are 
given below. 
1. [Anon.] Votes of Meeting of Western N. Y. Hort. Society, 
1890. Garden and Forest, Vol. III, p. 60. States that hypo 
sulphite of soda, though not a perfect remedy for pear scab, is 
‘the best one known at present. 
| 2. [Anon.] Scabby pears. Country Gentleman, Albany, N. 
Y, 1892, Vol. LVII, p. 47. Says spraying with conpen solution 
tee been tried without definite results. 
3. Artuur, J. C. Report New York State Experiment Sta- 
- tion, Geneva, N. Y., 1884, pp. 367-368. Describes the general 
appearance of, and damage caused by pear scab. Mentions 
fungicides which have been suggested by Burrill and by Saunders. 
4. Baitey, L. H. Bull. XIX, Cornell Experiment Station, 
Ithaca, N. Y., 1890, p. 49. States that J“. pyrinum has probably 
caused much of the failure in the pear crop this year. On p. 52 
states that the scab is abundant this season on the fruits. 
5. Breaon, 8. A. Report of the proceedings of the Western 
N. Y. Hort. Soc., Rochester, N. Y., 1893, pp. 14-20. The 
report of committee on plant diseases notes the prevalence of 
the pear scab during 1892 in western New York, showing that it 
caused considerable damage to the crop.
