Prof. Whitten — In reply to the question : I know no parasite of 

 the codling moth. The cabbage worm has a disease that keeps it in

SPRAYING IN 94. . 



* 



D .A. Robnett, Columbia — Spraying is no longer a thing to be ques- 

 tioned as to its possibilities. It has, in this age, become a necessity to 

 battle with the myriads of enemies to horticulture, and we believe that 

 -spraying, when scientifically done, will prove the boon for which we 

 seek. 



With me this work has been very unsatisfactorily carried on, but 

 in most cases it has been the fault of the operator, not of the principle. 



All spraying in our section, during the year 1894, has been done 

 by a few individuals and by our Experiment station. 



I know nothing of the results of any individual work, save my 

 own. 



Of the work done by our Experiment station I have some know- 

 ledge. I have watched this work with much interest. In my hand I 

 liold Bulletin No. 27, which has a full report of the four experiments 

 carried on by the Missouri station. I will read some extracts from 

 this work, but would advise all to order a copy to read in full. 



I have tried hard this year to get rid of the small purple ant-cows 

 or plant-lice, which were on my plum trees by the millions. I failed to 

 ■destroy them or the curculio either. I sprayed with coal-oil emulsion 

 time after time, using in connection: with it tobacco decoction, Paris 

 green and Cannon's fruit protector, all without satisfactory results. 



With my tomatoes I had wonderfuyy good results. Until I began 

 spraying all my tomatoes rotted, but after using Cannon's fruit pro- 

 tector on them I had perfect tomatoes. 



I also came near losing my cabbage from worms and lice; again I 

 resorted to spraying with the same preparation, with fine results. Some 

 of my cabbage I ruined by getting my solution too strong; but this is 

 part of our education, remembering that failures often lead to success. 



The day is now upon us when every horticulturist must be up and 

 doing to conquer our many foes; and if spraying is our safeguard, the 

 sooner we learn how to spray, when to spray and what to spray intel- 

 ligently, the sooner success is ours.
