30 SPRAYING THE APPLE ORCHARD. 



trees, while only 5%, less than one fifth as much, was 

 wormy on those sprayed. Thus on the trees not sprayed 

 53% of the total crop was picked free from worms, making 

 3 1-5 barrels, worth $3.20 net, while on those sprayed 72%, 

 or nearly half as much more, was picked free from worms, 

 making 4 1-3 barrels per tree, worth $-4.33 net. Deduct- 

 ing the cost of spraying, there was, therefore, a net profit 

 of just $1.00 per tree. 



Spraying at Greenland, N. H. — Twenty-eight Baldwin 

 trees were sprayed in the orchard of William H. Weeks, 

 the records of five unsprayed trees being made. Unfortu- 

 nately the records of the number of picked fruit were acci- 

 dentally destroyed of all except four sprayed and three 

 unsprayed trees. These trees, however, were scattered 

 among those sprayed, and show a very fair average of the 

 condition of all ; indeed, they show rather less benefit than 

 many. This orchard was much worse infested with the 

 codling moth than those at Walpole or Hancock, though 

 the orchard was fully as well kept. From the unsprayed 

 trees three fourths of the fruit dropped as windfalls, while 

 on those sprayed but 15%, or one fifth as many, dropped. 

 Of the fruit left to be picked on the unsprayed trees, two- 

 thirds was wormy, leaving but 8% of the season's crop to 

 be picked free from worms, making about one-half barrel, 

 worth fifty cents net. On the sprayed trees only 1-11 of 

 the picked fruit was wormy, leaving 70% of the total crop 

 to be picked free from worms, making 4 1-5 barrels, worth 

 $4.20 net. These trees bore about 3,600 apples per tree for 

 the season. On eight other trees from which the record of the 

 picked fruit was secured, but two to four per cent, were 

 wormy. Thus these trees would show $3.70 worth more 

 fruit on the sprayed trees, which means a net profit of at 

 least $3.55 after deducting the cost of spraying, from the 

 control of the codling moth. Such would be the value of the 

 spraying were all the unwormy picked fruit of good size 

 and not otherwise injured, but in this orchard much of the 

 picked fruit free from worms was too small for No. 1 size
