lime-sulfur, for the early spray, say, when the bud is pink? 



DR. FELT. I don't care to take a position on that one 

 way or the other, it not being an entomological question. 



MR. STAPLES. It is claimed in good authorities that 

 the lime-sulfur is entirely equal to that work, and I wanted 

 to ascertain if it is, that's all. 



THE PRESIDENT. I will ask for an expression of 

 opinion from the audience. 



MR. IVES. I probably haven 't got percentages in com- 

 paring these things, but it is generally recognized that 

 Bordeaux has been the better and stronger. The only 

 truble is that it is too strong at certain periods and does the 

 work too well, sometimes causing rusting and injury to 

 foliage. I have never had that trouble, but on certain 

 varieties you will have more than on others. I doubt if the 

 Spy will be affected by any spray ; certainly not by Bordeaux 

 or sulfur. 



MR. MARGESON. I would like to ask if we can use 

 arsenate of lead and tobacco together as a dormant spray 

 for bud moths? 



DR. FELT. They are being used in New York State. 

 They are making an application of lime-sulfur, and leaving 

 the spraying for the San Jose scale until the leaves get out a 

 distance of a quarter of an inch and sometimes even until 

 the pink shows in the blossom, putting on a lime-sulfur wash 

 and Black Leaf 40, and arsenate of lead, and are not getting 

 material injury. They are using it in the central fruit grow- 

 ing section of the state, and there has been an insistent 

 demand in that section for an opportunity of putting on the 

 poison in connection wath jthe San Jose Scale spraying. The 

 only advantage I can see from that is that when you delay 

 treatment until you have something green to put your 

 poison on, you can get some of those early leaf feeders, and 

 in that section we have one or two which may possibly be 

 very serious, namely, the leaf roller, which has destroyed 

 fruit in several orchards in recent years, and which begins 

 feeding and works right down into the buds and ordinarily 

 escapes the usual poison spray. The only way to get at it 

 in time is by putting on the poison just as soon as the first 

 green shows, and then you have a decided advantage. I
