114 Maine Agricultural Experiment Station. 1918. 



Plot 6. Standard dilution lime-sulphur and arsenate of lime. 



The records here were practically identical with those for 

 plots 2 and 5. 



Plot 7. Standard dilution lime-sulphur and "T. P." arsenate 

 of lead. 



The general condition of the foliage on plot 7 was decidedly 

 better than was the case on any other in the series. At the close 

 of the season only relatively small amounts of scab could be se?n 

 on the foliage and fruit and very little leaf injury was present. 

 Plot 8. Standard dilution lime-sulphur ; no arsenical added. 



The amount of scab on the leaves appeared about the same 

 as on plots 2, 5 and 6. Only a very little leaf spotting and burn- 

 ing was observed and this was not apparent at the close of the 

 season. 

 Plot 9. Unsprayed check. 



Scab was very prevalent on the unsprayed plot from the 

 time it first appeared. Injury to the margins of the leaves was 

 also noted. 



Plot 10. Sherwin-Williams Co. dry lime-sulphur, plus acid 

 arsenate of lead. 



Except for possibly slightly more leaf injury, very little 

 difference could be detected between the condition of the foli- 

 age on the trees on this plot and on plot 5 where, on the last 

 named, ordinary home-prepared lime-sulphur and a similar 

 amount of arssnate of lead were used. 



Effect of tfie Different Sprays on the Fruit in 1917. 



On account of the small crop, the sample taken for sorting 

 included the fruit produced on the inside of the two outside 

 rows as well as the middle two rows of each plot. Except on 

 plots 4, 8, 9, and 10 from which 2, 8y 2 , 5%, and $ l / 2 barrels 

 respectively were obtained the sample varied from 12 to 20 

 barrels. The following Table III gives the results obtained 

 from sorting.
