72 STATE POMOLOGICAL SOCIETY. 



thouf^ht best to prove for ourselves the effectiveness of the remedies, 

 — if they are effective. 



Unfortunately there are no large orchards in the vicinity of the 

 college, hence we have labored somewhat at a disadvantage. Much 

 credit is due to the gentlemen who gave the use o' their orchards 

 and so faithfully assisted in the work. I shall give as concisely as 

 possib'e the results of the past season's work in the line of "experi- 

 ments in spraying." 



CODLING MOTH {Carpocupsa Pomonelld). 

 A Dest which is universal in the southern portion of the State, 

 and one which in many sections is the most serious we have to meet, 

 is the larva of the codling moth. I say in the southern part of the 

 State, for I am informed by growers in northern Aroostook that 

 this pest has not yet reached them. No doubt all are familiar with 

 the larva as it appears in the fruit. The moth itself is small, 

 and very delicate. As it seldom flies during the day, it is not often 

 seen unless one is searching for it. 



IS SPRAYING WITH PARIS GREEN A PREVENTIVE? 



To answer this question, trees were sprayed in the orchards of 

 Messrs. W. P. Atherton of Hallowell, Charles S. Pope of Manchester, 

 and F. M. Woodward of Winthrop. 



In Mr. Atherton's orchard a row of Rhode Island Greenings, and 

 a row of Hubbardston Nonsuch were selected. Four of the 

 Greening trees were sprayed with Paris green in the proportion of 1 

 pound to 250 gallons of water ; an equal number in the proportion 

 of 1 pound to 300 gallons, and three trees were left unsprayed. 



Of the Hubbardston, one tree was sprayed with the mixture of 

 1 pound to 250 gallons, two in the proportion of 1 pound to 3"(0 

 gallons, and two were left unsprayed. 



Two applications were made. The first one, June 11th, just as 

 the last blossoms were falling was under my own supervision. A 

 second application was made b^^ Mr. Atherton two weeks later. 



The fruit was gathered October 3d. With the help at command 

 we were unable to gather the fruit from all of the trees. Therefore 

 in case of the Greenings, two trees of each lot were taken, reference 

 being given to the relative size and productiveness of the tree so far 

 as possible. All of the fruit was picked from the trees, and all that 

 had dropped was gathered separately. 



Table 1 indicates the comparative results.
