DISCUSSION 



What is the formula for the Cordley mixture? 

 125 pounds of sulfur 

 60 pounds of lime 

 50 gallons of water 



This should be boiled for two hours and then diluted 

 to 50 gallons. When ready to use 10 parts of water should 

 be added to one part of the mixture, and it may be applied 

 either hot or cold. If kept warm it can frequently be car- 

 ried over and used another time. 



Scalecide is a very good form of oil of good service in 

 controlling many sucking insects. Can be applied to trees 

 in summer when in foliage. Nine times get as good results 

 in controlling the San Jose scale with lime-sulfur wash as 

 with oils. Three-fourths of the practical fruit growers 

 use some form of lime-sulfur wash. I should not advise the 

 use of either the Cordley wash or commercial washes on 

 leaves. These are used for the San Jose scale but should 

 never be used on foliage. Some have done this and not had 

 much injury result, but I should prefer to use it earlier. 

 About seven or eight years ago I tried using miscible oils 

 later in the season, because I wished to destroy the young 

 scale. Gave it a thorough trial and we found that so far 

 as controlling- or killing the San Jose scale it was not a 

 success. 



Question. Is the lime-sulfur-wash used as a fungicide* 



Answer. Yes, and it is claimed to be quite efficient, 

 but the spraying properties depend upon the amount of 

 soluble sulfides in the wash, and that depends upon the lime 

 and the way it is slacked. It may be done. I don't want 

 to recommend it.. 



Question. What kind of a boiler should be used? 



Ans. You can use most any kind that will boil. If 

 you boil ,boil, don't simmer. We found that we could pre- 

 pare this wash in the minimum time by heating the water 

 first, then dumping in the lime and put in the sulfur right 

 on top. The only trouble in doing this is that the sulfur is 

 apt to collect in little balls, but a vigorous stirring will 

 break these up. 



Question. Would you not get greater heat by using 

 less water? 



Ans. If you use warm water and are simply slacking
