 Arsenate of lead is to be found on the market both as a 

 powder and as a putty-like paste, which latter must be 

 worked free in water before it is added to the lime-sulfur 

 mixture or to Bordeaux mixture. The paste form of the 

 poison is largely used at the rate of 2 or 3 pounds to each 

 50 gallons of the liquid and is added to it after it has been well 

 worked free in water. As there are numerous brands of 

 arsenate of lead upoji the market, the grower should be 

 careful to purchase from reliable firms.
