Q. Dr. Smith: Have you ever used copper solution 

 for fungus troubles, spraying when the trees were in dor- 

 mant condition? 



A. Professor GuUey: Yes; and I have used the sul- 

 phate of copper alone and am satisfied that for ordinary 

 cases of the fungus winter spraying is unnecessary; if you 

 wait until the foliage is coming out it is ample time. I 

 like the Bordeaux Mixture better than the copper sulphate 

 because of its sticking qualities. 



Q. Do you use crude petroleum clear for exterminat- 

 ing San Jose scale? 



A. Professor GuUey: Yes. 



A. Professor Beach : The use of crude petroleum for 

 this scale has been tried in New Jersey with success, but 

 the matter is still in the experimental stage and there is 

 still a doubt as to what the effect will be on trees. 



Q. Is fumigation sure to kill the scale? 



A Professor Britton: I do not believe it will wholly 

 exterminate it, for it is like the poor — always with us. 

 Fumigation of nursery stock, however, is a good thing; it 

 is the most effectual of all treatments, yet live scale is 

 found upon stock fumigated after this method. 



A. Mr. Innis: Isn't it wise to try the petroleum 

 treatment any way, as the tree will die if left to itself and 

 if you kill it with the oil it is only a little quicker? 



A. Professor Britton : It seems wise to try the experi- 

 ments. 



Further discussion upon the use of crude petroleum 

 showed it to be in such an experimental stage that it 

 seemed best to leave it to the Experiment Stations for 

 another year. 



Mr. Merriman: Last year I had San Jose scale on 

 some Japan plums and I sprayed them with a strong solu- 

 tion of copper sulphate; it killed the majority of the scale, 

 and so saved the life of the trees. 



A. Professor Beach : I would like to ask Mr. Merri- 

 man if this spraying was done when the trees were in a 

 •dormant condition. 



A. It was. I made three applications; all when the 

 trees were in dormant condition.
