REPORT OF THE STATE ENTOMOLOGIST KJl6 35 



latter, it should be noted, produced 3423 apples, a decidedly larger 

 crop than that from any of the sprayed trees. This large yield 

 explains in considerable measure the low percentage of wormy fruit 

 on the check trees. There is no question but what material benefits 

 in the control of the codling moth were obtained in this orchard 

 though the large variation in the yields of different plots, and 

 especially of the check trees, makes a fair comparison impossible. 

 It is interesting to note that the proportion of " shallow " injured 

 fruit on plots 1-3, as compared with the total wormy, does not 

 vary greatly from the proportion on the unsprayed tree. 



Newfane Orchard 



This work was conducted in cooperation with Mr G. H. Stahler 

 of Newfane, his orchard being located close to the stop known as 

 Jacques road. The trees are Baldwins, about 40 years old, set 

 approximately 38 feet apart and stand in sod. The orchard has 

 had a reputation of producing large crops of apples and is in good 

 condition. 



Plot 1 was located on the eighth and ninth rows from the west 

 side and comprised the eighth, ninth and tenth trees from the south 

 end. 



Plot 2 was located on the fourteenth and fifteenth rows from the 

 west side and comprised the ninth, tenth and eleventh trees from the 

 south. 



Plot 3 was in the same rows and comprised the fourth, fifth and 

 sixth trees from the south. 



The check trees were on the eighth and ninth rows near plot 1 

 and were the twelfth from the south end, there being only one tree 

 intervening between the northern trees of plot 1 and the check trees. 



The first application was made with the wind on the morning of 

 June 2d, the day being sunny and with light and fitful breezes. 

 One man sprayed from the top of the tank, using three nozzles 

 which delivered the spray in nearly parallel lines. The work was 

 continued until there was some dripping and the application was 

 made only with the wind. The blossoms were all off and the stamens 

 shriveled although there was no closing of the petals. The work 

 started with one spraying outfit, a pressure of 150 pounds being 

 used and the application being made to the east side of trees 1, 3 

 and 5 of plot 1, and then owing to engine troubles another spraying 

 outfit was substituted with a continuance of the same type of 

 nozzles and method of application. The pressure in this latter 

 case was 250 pounds and the application was made to the east side
