Then get busy. That's a sure sign of Aphis. 

 These little insects are sucking the life out of your 

 trees. Kill them unless you want a small crop of dwarfed, 

 specked fruit. You also run the risk of Aphis killing your trees.

Recommended by agricultural colleges and experiment stations. Don't 

 make the very common mistake of thinking that Lime-Sulphur, Arsenate 

 of Lead or Bordeaux kills Aphis. They don't, but if you are using 

 those sprays, simply add Black Leaf 40 properly diluted, and make one 

 spraying do double duty.. Aphis also attacks Peach, Plum, Cherry 

 as well as many vegetables and plants. Black Leaf 40 is highly 

 concentrated so that only a small amount is required. The cost 

 is small — only a few cents per tree. Free Spray Chart. Your 

 dealer has Black Leaf 40 and one of our free spray charts. If /

Pollination of Filbert 

 Varieties 



(C.o/?tinued from fage 11) 



abnormal year rather than just enough for 

 the normal year. 



The Daviana works best on Du Chilly 

 and less on the Barcelona and the White 

 Aveline does the reverse. Clackamas is 

 excellent for Du Chilly, but not for 

 Barcelona. Alpha is excellent on Du 

 Chilly. Nottingham and Cosford are both 

 excellent on Barcelona, but lighter on Du 

 Chilly. These two latter varieties gave 

 the best results on Barcelona, but are very 

 scarce. 



For some time to come it will be neces- 

 sary to plant the varieties at hand even if 

 later experiments show that these odd 

 varieties being tested are sufficiently good 

 to warrant propagation. Even with the 

 varieties at hand it will be difficult to furn- 

 ish the proper number of pollenizers and 

 mav be necessary to limit the number to the 

 minimum. 



With the development of the filbert 

 industry came the usual confusion and as a 

 result there is considerable uncertainty as 

 to the names of varieties being distributed. 

 For that reason it would seem advisable for 

 the prospective grower to purchase all his 

 nursery stock from one man and use the 

 combination of varieties that is giving the 

 seller good results in pollination. 



Experimental work has not been carried 

 on far enough to establish for a certainty 

 the best pollenizers for any one variety. 

 Future work may upset some of the data at 

 hand, but one thing seems to be certain, 

 filbert varieties are self-sterile.
