BROWN-ROT OF PRUNES AND CHERRIES. 9 
_ The first and fourth applications have been especially important 
_ the past season. 
BLOSSOM INFECTION OF CHERRIES. 
Observations made near Vancouver, Wash., on April 8 and in the - 
vicinity of Salem, Oreg., on April 13 showed that there had been 
a blossom infection of cherries similar to that already described 
on prunes (PI. I, figs. 1 and 2). On the latter date Monilia was 
fruiting luxuriantly on the blighted cherries. It appeared that 
most of the infection had taken place after the petals had fallen and 
before the fruit had had a chance to push through the husk. Black 
Republican cherries seemed especially badly infected. Estimates 
| made on April 13 indicated that on this variety fully 90 per cent of 
_ the blossoms were infected with Monilia, and in many orchards of 
_ other varieties at least 75 per cent were similarly infected. A grower 
. near Felida, Wash., sprayed some of his cherry trees while they were 
in full bloom, using lime-sulphur solution diluted 1 to 30. He delayed 
_ the spraying of the others until the calyx browning had begun to 
appear and then applied the same spray he had used earlier. Counts 
"made on April 8 of representative branches from each lot of trees 
_ showed 9 per cent of infected fruit in the former case and over 40 per 
cent in the latter. Spraying trees in full bloom is not to be recom- 
_ mended, but the results show the value of early spraying. 
BROWN-ROT OF CHERRIES. 
Spraying experiments for the control of brown-rot on the fruit 
_ were carried on in the orchard of L. T. Reynolds, of Salem, Oreg. 
The work was begun late in the season. The first application was 
made on May 7 and 8, when the fruit had begun to color, and a second 
on June 1, when the fruit was approaching maturity. The latter 
_ application was delayed for nearly a week on account of rain. 
Plat 1 received Bordeaux mixture, 2—4—50, plus 2 pounds of resin- 
fishoil soap; plat 2, commercial lime-sulphur, 1 to 50; plat 3, self- 
boiled lime-sulphur, 8-8-50, plus 2 pounds of resin-fishoil soap; and 
plat 4 was unsprayed. 
No injury resulted from the use of any of the fungicides. The 
Royal Ann cherries were picked on June 17 and the Black Repub- 
heans on June 24. A regular 10-pound box of sound cherries was 
packed from each plat and placed in cold storage at 40° F. until 
June 27, and the fruit was then shipped by express to Wenatchee, 
Wash. Notes on the Royal Anns were taken on July 2 and on the 
Black Republicans on July 6. The former were thus in cold storage 
at 40° F. for 10 days and at air temperature for 6 days, the latter in 
cold storage for 3 days and at air temperature for 10 days. Table 
ITT gives the results obtained.
