Mix the two materials and apply in the form of a powder. 

 The mixture was formerly supposed to possess strong f ungicidal 

 properties, but it is now little used. It is of some value in 

 treating surface mildews, the sulphur probably then being the 

 active principle.

SULPHATINE POWDER. 



Anhydrous copper sulphate 2 pounds. 



Flowers of sulphur 20 "

The ingredients should be thoroughly mixed, when they may 

 be applied. The powder is supposed to be of value as a fungi- 

 cide, but is very little used.

SULPHOSTEATITE J CuPRIC-STEATITE ; FOSTITE. Sul- 



phosteatite is an exceedingly fine blue powder consisting of 

 steatite or talc, and containing also from 2 to 10 per cent of 

 copper sulphate. It is obtained in Europe, and was first intro- 

 duced into America by C. H. Joosten, of New York, in 1893 ; 

 he changed the name to "Fostite" the following year. The 

 copper contained in the powder is largely soluble, and in con- 

 sequence foliage is frequently injured by the use of the fungi- 

 cide. It has been recommended as an insecticide, but I have 

 failed to derive any benefits from its use for this purpose. It 

 is not so valuable as other copper compounds, yet it has the 

 desirable quality of being remarkably adherent to foliage. 



SULPHUR; FLOWERS OF SULPHUR; S. Sulphur is valuable 

 both as an insecticide and as a fungicide. Its use for the first
