42 BOARD OF AGRICULTURE. [Pub. Doc. 



of the best fungicides we have ever used ; but for several years 

 it has rusted the fruit so as to hurt its attractiveness very 

 much. Then came in the commercial lime and sulphur 

 sprays, which, if not used w^ith caution, are liable to injure 

 the foliage, and sometimes do not control fungus as well as 

 the Bordeaux. I have used the self-boiled lime and sulphur 

 solution (Scott's formula; Scott of the United States Depart- 

 ment of Agriculture) on apples and peaches. On apples I 

 have used it at the rate of 10 pounds of lime and 10 ])oun(ls of 

 sul])hur to ;")0 gallons of water, and then added 2 to 3 pounds 

 of arsenate of lead, spraying just as soon as the blossoms drop. 

 In Massachusetts, where the gypsy and brown-tail moths are 

 prevalent, I would use at least 5 and even 10 pounds of arse- 

 nate of lead in cases Avhere the moths were numerous. 



The self-boiled solution is one of the cheapest and one of the 

 most effectual solutions for spraying. You take, say, 10 

 pounds of good rock lime and heat it, or apply enough water 

 so that it will begin to slake, and then sift in the powdered 

 sulphur. Cook the sulphur by the heat of the lime. Let that 

 slake until the lime is all disintegrated, and keep adding 

 water. When a slight orange precipitate is being formed, 

 stop the action by drenching with cold water ; otherwise sul- 

 phides, injurious to foliage, will develop. Possibly this is a 

 little more complicated than using the commercial solution, 

 but in spite of that I prefer it for apple spraying, and for 

 peaches would not use anything else, only I would use j\Ir. 

 Scott's formula, — 8-8-50 instead of 10-10-50. 



Mr. Reed. How many times do you spray in the summer 

 time ? 



]\rr. Drew. Some seasons vary and some apples vary. 

 The first spraying is the all-important spraying. It should 

 be applied with force, thoroughly and just as the blossoms 

 fall. It should be repeated about two or three weeks after- 

 wards. That generally will be sufficient for such varieties 

 as the Baldwin, and those not subject to fungus. For the 

 Fall Pippin or Spy or Greening, or some of those more sub- 

 ject to a fungus, three or four sprayings are not any too many. 



Mr. H. A. Parsons. Is it too late now [December 5] to 

 spray, if you did it on a warm day?
