EXPERIMENTS ON THE APPLE WITH SOME NEW FUNGICIDES. 19 



Arsenate of lead, 2 pounds to the barrel, can be used in any of the 

 mixtures tested. When used alone this insecticide seemed to possess 

 considerable fungicidal value, though probably not enough to be de- 

 pended upon for general use.
