the
most satisfactory results, however, from applying the arsenical spray
separately, just after the blossoms fall, because of the physical
impossibility of properly applying the two sprays--the driving and the
mist spray--together. For most practical purposes on the general farm,
three sprayings are necessary in order to secure clean fruit and four,
sometimes five, are often advisable. These may be summarized as
follows:

1. With lime-sulphur, winter strength, on the dormant wood in
early spring.

2. With lime-sulphur and arsenate of lead just before the
blossoms open (may sometimes be omitted).

3. With the same (or Bordeaux for scab) just after the blossoms
fall.

4. With the same two or three weeks later.

5. With arsenate of lead eight or nine weeks later (may
sometimes be omitted).

(In the south and middle latitudes where bitter rot and apple
blotch occur two other sprayings may be necessary.)

6. With Bordeaux about eight or ten weeks after the blossoms fall.

7. Again with the same about two weeks later.
