No. 6. DEPARTMENT OF AGRICULTURE. 7bD 



PROF. BUTZ: The letter in relerencc to fruit packages, from the 

 Department of ^Vasilington, wliioli was read by the Secretary, 

 should have some attention by this Association. I move that a com- 

 mittee of three be appointed by the Chair to draft resolutions and 

 submit them to the Society for approval. 



The resolution was adopted and Messrs. Butz, Hiester and Peters 

 were appointed. 



The CHAIK: Will Prof. Butz give us some information concern- 

 ing the "dust spray" recently introduced? 



PROF. BUTZ: These sprays have been upon the market several 

 years. If the proper materials are used, and results prove satis- 

 factory they ought to be adopted. They are more easily prepared 

 and much less bulky and troublesome to handle than the liquid 

 sprays, and this is a great point in their favor. In practice, how- 

 ever, they have not proven so effective as the liquid sprays. 



I was interested in some vineyard spraying that was done in Erie 

 county last summer, and in no instance was dry spray used. In two 

 adjoining vineyards one was sprayed, the other not. In the one 

 sprayed there was no rot, while in the other nearly all rotted. The 

 grapes from the one went to a good market, the other to the vine- 

 gar factory. The liquid spra}'^ dried on the leaves and kept the 

 fungus down. I doubt v.iiether dust spray will be as effective, and 

 the matter can only be decided by experience. 



PROF. SURFACE: I felt interested in this spray and, for in- 

 formation, wrote to the parties in Missouri who introduced it. It 

 is claimed to be effective as against codling moth, but not effective 

 as a preventive of plant diseases. In its preparation, a new com- 

 pound was formed which was not copper sulphate, and consequently 

 not a Bordeaux mixture. We need a dust spray in which we pre- 

 serve the copper sulphate, and which should be made according to a 

 formula which I will publish in my March or April Bulletin. I have 

 great hope for it as an efficient spray. 



A recess of 5 minutes was taken after which the Committee on 

 Legislation submitted the following report: 



"Whereas. A most destructive insect pest known as 'San Josd 

 Scale' has appeared in three-fourths of the counties of Pennsylvania, 

 and 



"^^'h(M•eas. This serious pest attacks all varieties of fruit trees and 

 many other trees and shrubs, including ornamental shrubbery and 

 hedges, killing them in from one to five years, and 



''Whereas. The habits, enemies of and remedies for this pest need 

 furtlier investigation and careful experimentation in order to give 

 us simple and effective means for its suppression, and
