EXPERIMENT STATION BULLETINS 335 



Sterling is a comparatively old variety of American origin; a very 

 beautiful fruit, well adapted to early marketing, and specially exempt 

 from blight. 



APPLES.— (Pj/rws malus). 



Apples, while yet dormant, were on April 13th to 17th treated with the 

 strong solution of copper sulphate, in common with other fruit trees. 



Bordeaux mixture with Paris green was applied for codling moth on 

 May 11th to iHth, the treatment having been delayed by high winds. 



On May 23d to 27th the treatment was repeated, using one pound of 

 copper sulphate and three ounces of Paris green in 250 gallons of water. 

 This treatment was again applied on June 11th, and a final spray of the 

 same was given on July 3d. 



These several treatments appear to have been thoroughly effective 

 against the attacks of fungi, though, possibly consequent upon delayed 

 treatment during windy weather, they were but partially effective against 

 the codling moth. 



Tobacco decoction, made by digesting tobacco stems for several hours 

 in cold water sufficient to cover Ihem when slightly weighted, proves to be 

 a specific against aphides. These have been rather persistent this season. 

 In subduing them, this spray was first applied on July 8th to 10th, and 

 again on the 25th. 



Only such varieties as have bloomed or fruited this season are included 

 in the following table 



Crabs are compared with crabs only, so far as quality is concerned. The 

 word crab, where it appears, is not to be understood as part of the name.
