e designated as follows:

1. When buds are still dormant.
2. When blossom buds begin to show pink.
3. When fruit is size of a pea.
4. Two weeks after third spraying.
5. When fruit begins to color.

It did not pay to apply Spray 1. In the plots on which applications 1,
2, 3 and 4 were made there was an average of 6.3 per cent. of rot, while
in those from which Spray 1 was omitted there was an average of 6.7 per
cent. rot, a difference so slight as to be negligible. Neither did Spray
4 seem to pay, there being an average of 10.9 per cent. brown rot when
it was applied and 11.4 per cent. when it was omitted.

The schedule finally adopted was therefore the application of Sprays 2,
3, and 5. Spray 2 is necessary to prevent blossom blight, although it
has not always reduced the amount of rot on the fruit. Spray 5 is the
most important in reducing the amount of rot. In all of the experiments
during three years the average amount of rot in the sprayed plots which
did not receive Spray 5, was 10.7 per cent. On the plots which received
Spray 5, with or without the other sprays, the average amount of rot was
4.6 per cent., and the average on unsprayed plots was 34.8 per cent.
Excellent results were sometimes obtained by applying only Spray 5,
although this did not, of course, have any effect on blossom blight. In
1913 the amount of brown rot in one plot which received only Spray 5 was
3.3 per cent., while in the unsprayed plots it was 33.9 per cent. In
1914 the amount of rot was reduced from 38.8 per cent. in unsprayed
plots to 6.5 per cent. in the plots to which Spray 5 was applied.
Possibly Spray 3 could be omitted without seriously interfering with
results; success in controlling the rot with Spray 5 alone seems to
indicate this. It was hoped to settle the matter during the past summer,
but spring frosts spoiled the experiment.

For the present it seems advisable to recommend the application of
Sprays 2, 3, and 5. In the first two, two and a half pounds of arsenate
of lead paste, or one and one-fourth pounds of the powder should be
added to each fifty gallons of spray mixture in order to kill the
curculio. In the plots sprayed in this way in 1911 ninety-six per cent.
of the fruit was perfect, while in the unsprayed plots only 81.6 per
cent. was perfect, and in 1913 and 1914 the amount of brown rot was
reduced from 34.8 per cent. to 4.6 per cent. Several growers have
reported excellent results from these three applications,
