In addition, a spray was applied to an older orchard composed en- 
tirely of 25-year old Ben Davis trees. These trees had been badly neg- 
lected and over half of the orchard was dead, the remaining trees being 
almost entirely incrusted and showing numerous dead branches. This 
orchard was treated in the following manner: 
Plot 1—Commercial lime-sulfur solution, 1 gal. to 8 gals. water 
2—Niagara soluble sulfur, 1214 lbs. to 50 gals. water 
3—B. T. S., 14 Ibs. to 50 gals. water 
4—Dow dry lime-sulfur, 15 lbs. to 50 gals. water 
5—Sherwin-Williams dry lime-sulfur, 15 Ibs. to 50 gals. water 
6—Martin-Senour dry lime-sulfur, 12% lbs. to 50 gals. water 
7—Check: unsprayed 
This orchard was carefully examined on June 11, and-again on 
Sept. 22. The scale was still numerous on many of the heaviest infested 
trees, as it would be impossible to clear up this orchard entirely with one 
treatment. A summary of the results obtained from this grading is as 
follows.
