very serious question with us. We now offer buds from 

 vigorous trees that we know or are reasonably sure are free 

 from "yellows, " to oUr nurserymen, trying to get them to 

 propagate, trees from these buds. I think that the common 

 practice of taking buds from the nursery trees for the prop- 

 agation of more trees is very dangerous. After the "yel- 

 lows" once starts in the nursery it is easily carried from one 

 tree to another by budding and a large number may be 

 inoculated each year. Both yellows and little-peach are 

 very serious with us, but they have been, able to control them 

 if the trees are taken out at the first indication of disease. 

 "J'bat is an important point. The average grower does not 

 notice the yellows on his trees until it is in the advanced 

 tj.tage, and by that time it may have infected a dozen sur- 

 rounding trees. It is a great temptation, if a man plants a 

 peach orchard, to plant some peach, trees and care for those 

 trees, three or four years as the case may be, up until the 

 time he sees the first crop, and about that time he sees un- 

 mistakable signs of yellows, and he says, "I am going to get 

 that .first crop. I hare taken care of the, trees. I will get 

 this crop, and then I willpun the trees put." I have heard 

 that said -many times, but in the inearitime; the. chances are 

 that the-tree has infected three or four or half a dozen trees 

 right around it. V ''' '■ /., ..^,. .- - 



ME. DICKINSON :-'l Would like to ask as to the control 

 of the a|)his on the apple, and whipther the. combined spray 

 for aphis and scale is possible. ,, 



PROP; FARLREY: I think it is possible, provided you 

 use concentrated lime-sulfur. That will help control the 

 aphis. If you see the aphis on the buds at that time, the 

 application of concentrated lime-sulfur at scale strength will 

 assist in controlling your aphis. 



THE PRESIDENT :Does it have any effect on the eggs? 



PROF. FARLEY : I doubt it. It may prevent some of 

 the eggs from hatching, but not very many. We generally 

 depend upon the tobacco decoctions, using those together 

 Avith the concentrated lime-sulfur. We have had better re-
