ORCHARD SPRAYING IN 1916. 



113 



Mr. Simmons : Generally speaking, in about two weeks. 



A Member : How about the dormant spray? 



Mr. Simmons : I never use it. 



A Member : In the spring what is it that kills the foliage, 

 the lime-sulphur or the arsenate of lead? 



Mr. Simmons: Lime-sulphur when it doesn't dry good is 

 liable to kill the foliage, but that is only occasionally. The injury 

 two years ago was very slight, but I think, ordinarily speaking, 

 where you get the spray dope to dry out fast on the trees there is 

 no danger of injury when it is used the generally advocated 

 strength, five quarts to fifty gallons. 



Mr. Simmons' orchard in full bloom. 



Mr. Baldwin : Relative to the second spraying with arsenate 

 of lead. I have used that and used it exclusively, never using a 

 bit of paris green, for twelve or fourteen years. When I spray 

 potatoes I spray them when they are half grown, and then 

 the next lot just as soon as they get new foliage. The bugs would 

 never think of touching the old foliage, they are after the new 

 foliage. We spray the first time before the leaves are half leaved 

 out, and the worms know the difference between the young leaves 

 that are succulent and the old ones. If we don't put poison in 

 the second spraying we have a lot of leaves the worms are going 

 to attack, and there is just the place we want to get them. I 

 think we ought to spray the second time to get the worms ; they 

 are not going to eat the old foliage that has the poison on. 



Mr. Bingham: I would like to ask the gentleman why he 

 sprays the second time if he does not consider the addition of 

 arsenate of lead of any particular advantage. We know that 

 lime-sulphur in all sections does not control fungous diseases. 

 Why do you spray the second time if you don't use the arsenate 

 of lead with new foliage coming on all the time?
