might say in regard to this leaf roller that experiments in the 

 West, and some conducted by Professor Herrick of Cornell, 

 would indicate that the spraying in the spring or during the 

 dormant season with a miscible oil or petroleum emulsion is 

 perhaps the most effective method of checking them when 

 abundant in an orchard. 



MR. MILLER, I am pretty firmly convinced that the 

 simpler we keep our spraying mixture and the more effec- 

 tive we are in the use of them, the better results we will get. 

 The average fruit grower is apt, when he gets into the realm 

 of various spraying mixtures which we have today, to be- 

 come confused. I feel that with a good thorough application 

 of the lime-sulfur compounds for the dormant spray we can 

 control most of the scale insects and the fungus troubles, 

 and then when we get into the summer season where we are 

 liable to get the codling moth and the chewing insects, at 

 that time, if we have thoroughly worked with the lime-sul- 

 fur, I believe we can thoroughly control the chewing insects 

 with the arsenate' of lead. Now, I hope that every fruit 

 grower here today, whatever else he may get from this dis- 

 cussion, will go home with the idea that if he uses these two 

 spraying mixtures thoroughly, he can practically control the 

 entire situation as relating to the production of perfect fruit. 

 I would suggest with relation to the liriie-sulfur that the 

 mixture may be made a little stronger than is ordinarily 

 recommended ; I believe about 6 gallons to 44 gallons of 

 water is the ordinary formula, but my rule has been about 

 S gallons and I have observed, as to practical results, that 

 the stronger the mixture up to that point, the better the 

 results are. I likewise believe that a little stronger mixture 

 of arsenate of lead than is ordinarily advised produces 

 better results, and I likewise believe that this spraying 

 problem should never be disassociated with the other factors 

 and the other essentials that are necessary in order to pro- 

 duce fruit. In other words, I believe that better cultural 

 treatment, more attention to pruning, is an important factor, 

 together with the thorough spraying, in order to grow the 

 fine fruit which we are trying to produce today. 



MR. IVES. I would like to ask Mr. Miller how he is 

 going to fight the pink and green lice. There is a scourge 

 of it here.
