FUNGOID PESTS OF CULTIVATED PLANTS. 255 



Sulphatine. Mix two and a half pounds of anhydrous sulphate of 

 copper with fifteen pounds of finely powdered sulphur and ten pounds of 

 air- slaked lime. Apply in powder. 



Sulphur. This is used as a dry powder in the condition known as 

 " flowers of sulphur." It is most effective against the fungi which are 

 epiphytic, in which the mycelium is entirely superficial, forming a dense 

 white felt on the surface of the leaves, as in the Hop mildew, Rose mildew, 

 and Pea mildew. Sometimes finely powdered quicklime may be mixed 

 with the sulphur.
