April, '12] CODLING MOTH DISCUSSION 165 



Taylor, I can also vouch for their accuracy. In the Grand Junction 

 district, as the result of following the one spray and the one pound 

 of poison propaganda, the nunilier of worms increased until we found 

 in one orchard as an average of a long series of counts 42 eggs to an 

 apple. Gentlemen, think of what such a condition as that means. 

 One spray with one pound of jioison or ten ]K)unds of poison would 

 not touch such a condition. 



On the other hand, if Doctor Felt's experiments were under similar 

 conditions to those shown by Sanderson's tables, and they probably 

 were, there were less worms to kill in the second brood than there were 

 in the first. Under such conditions, any spray that is fairly efficient 

 in the first brood would be sufficient. If a worm was left in the first 

 brood, it might make half a worm in the second brood — not more, 

 while, in the western results, you will notice they increased from 10 

 to 16 times between broods, and Professor Quaintance shows increases 

 up to 80 and more times between the first brood and the second. 



Now, under the conditions found in Grand Junction, eight sprayings 

 did not produce sound fruit and thousands of Ijushels of apples fell 

 to the ground wormy, for which boxes had been ordered and all prepara- 

 tions made to ship. All this as the results of a false propaganda of 

 one spray and one pound of poison without regard to conditions. We 

 do not want any of that in the West. And, yet, there were whole 

 valleys in Utah this year in which there was not a single orchard 

 sprayed more than once. But, if those orchards should get more than 

 2 or 3 per cent wormy at the end of any given year, the next year they 

 would get more than one spraying. We do not talk one spray or 

 two sprays, we talk thorough spraying and holding the worms down. 

 You must keep in mind the difference in conditions out there and the 

 conditions that Doctor Felt has been talking about. There are high 

 freight charges on our apples, and in order that they may bring a 

 profit, they must be absolutely sound. You must also keep in mind 

 that the value of the western apples is their color, and the colored 

 apples are the ones on the outside of the tree, and those are the ones 

 most affected by the worms. Our efficiency must be five times what 

 yours is to have anything like the same results, so do not understand 

 that I am talking this spray for your people, but we have a condition 

 to meet in the western country which we cannot afford to fool with. 

 It is a fight to the finish with us and we have finished the codling moth 

 where we have gone at it right. 



Just one more thing, I made two mistakes in my first bulletin. I 

 want to correct them pul)licly. I stated that I used 85 pounds pres- 

 sure, and that was because the manufacturer said the pump furnished 

 that. I had no gauge on the pump at that time. Since putting a
