 In eonxinuation of this work, part Ava o4 the station report, just issued, lives tho results Of special work done in l91o and 1911 to test the relative vn1ue of the different summer sprays nov n ma This work was planned and executed with the cooperation of orch1fdist& by the station botanist and eatu1o36G1st, pr. c.

 It appears from this report that sprnying. while absolutely necessary under oome conditions and helpful un- der III. stfll has it's shady side. Some damage to fruit and foliage is to be rieties of both apple and peaches vary q good deal in their susceptibility to this spray injury and again certain sprays afe more likely to do damage than others.
 Ti1e report needs careful. readings and study to learn its full value and cannot be briefly summarized. The following general recommendations, however. are of Immediately practical value to all orehardists.
 APPLES.
 Winter treatment (spraying dormant trees) b necessary only in the case of the presence of the San Jose scale, when commercial lime-sulphur, 1-s. or miscible oils. 1-15. may be used.
 As rule. three summer treatments with . fungfcide are necessary to- con- trol the fungous diseases, and the last two of these should contain an in aectiside- These sprayings should be made as follows: First, just before the blossoms open. on the young un- folding leaves (April 27 to May 10. ac- cordtug to the season and variety): oecond, right after all the blossoms heve fallen (lday 10 to 30); third. about one month later Casually June 15 to 25) . Where fungi are not prevalent, es- pecially seab, the first treatment given above may be omitted. Occasionally peYhaps in alternate years, where fungi arc quite fnconspicuous and the trees have been thoroughly sprayed the pre- Vloup year, the fungictde may be en- tirely omitted, and only the two spray ings for insects may be given.
 For fuugtcides, we recommend Bor- deaux mixture of the 5-4-5O strength for the first spraying. and the 1-4-50 Tor the second and third sprayings; or cofnmercfd 1ime-sulphur. used at a 9trength of one and one-fourth gall lens for fifty gallons of water. for all thfoe sprayings- The former has bets lees likely to produce spray injury, specially russeting of the fruit. Where fungf are prevalent, the former might De uoed. while with varieties russet- i'm bu1ays as Baldwin, the latter Is liI ~ m nrove more satisfactor
