TWENTY-FIRST ANNUAL MEETING.

suppose that they did. They fed some upon the leaves possibly, 

 and finally coming" to the young fruit and generally working 

 their way in through the calyx end, that, of course, being the 

 small end of the fruit, and finally coming out, leaving the well- 

 known worm hole in the apple. They come down the tree and 

 make their cocoons under the rough bark of the tree, or per- 

 haps in the rubbish on the ground. 



In treating this pest I should use arsenate of lead. Of 

 course, if you have fungus troubles, it is all right to use it with 

 the fungicide. If you have other troubles, but for the codling 

 moth alone, the arsenate of lead will do the business. 



Some of you will want to know how many treatments to 

 put on. There should be two every year, one just after the 

 petals fall. Apply within a week or ten days after the blos- 

 soms fall, and then give a second application about one month 

 after the fruit. 



Now as to the arsenate of lead, we may use the dry pow- 

 der or the paste form. The advantage of the paste form is 

 that it adheres better to the foliage and remains exceptionally 

 better. It does, I think, remain in suspension better. If we 

 have a good agitator on the pump, we can get it upon the foli- 

 age in good shape. Whether it sticks better or not I am not 

 prepared to say, but last year we used over a hundred pounds 

 of one kind of paste arsenate of lead, and it stayed there a long, 

 long time. It certainly does not come off readily. I know it 

 was there long enough to control the codling moth. There 

 is no particular need of having it stick any better. On the 

 other hand, the dry form is easier to handle, and you do 

 do not have to pay for half water. You do not have 

 to pay freight on the water. I may say that the price is 

 usually twice as much as the other, so that the cost of the ar- 

 senate of lead per barrel would be about the same. We use 

 three pounds of paste to the barrel. We use one and one-half 

 pounds of the dry. The paste in the dry form is rather bad to 

 keep over because it dries out badh', while the dry will keep 

 indefinitelv. But it matters not very much which vou use. If
