Prof. Symons. One-third of a pound to 50 gallons. 



Member. What formula of Bordeaux ? 



Prof. Symons. I think it was 4-4-50 or 4-5-50. 



Member. Have you used "Pyrox"? 



Prof. Symons. — No, sir. 



Member. Did you make your own Bordeaux Mixture? 



Prof. Symons. Yes, sir ; we made our Bordeaux Mixture. 



I have shown you what we secured from one spraying. I urge

that every one of you who is trying to become an orchardist, consider 

 the fact that you have got to raise good fruit, and that you cannot 

 raise it without controlling the Codling Moth. I would therefore 

 urge one spraying, and preferably two sprayings. 



Member. When do you spray the second time? 



Prof. Symons. Two weeks after the first. Spray just after the 

 blossoms have fallen, and then ten days later. 



Member. Is that late enough to catch that second brood? 



Prof. Symons. No; the second brood does not appear until 

 July ; a third spraying is necessary to control this, but is more 

 likely to russet the fruit at that time. The second spraying is im- 

 portant, however, to take care of the late-appearing moths from 

 first brood. 



Member. The first spraying would not take care of^the later- 

 emerging moths ? 



Prof. Symons. No, sir; except that it would reduce the num- 

 ber of moths for a subsequent generation. 



Mr. Dunlap. Is there any chance of catching the moth? 



Prof. Symons. No, sir; it is very tiny. 



Mr. Dunlap. Are not bands sometimes used to catch the 

 moths ? 



Prof. Symons. Yes ; that is one means of catching' them. If 

 you have not sprayed thoroughly, reaching every calyx, the banding 

 is of value in catching the escaped larvae. These larvae emerge 

 from the calyx, crawl down the tree, and enter any available crevice. 

 If you have a band around a large limb, or around the trunk, usually 

 the larvae wilLgo in under this band, and can thus be readily cap- 

 tured and destroyed, thus preventing a second generation. \\'e have
