 INSECTICIDES AND FUNGICIDES. 



FOR BITING INSECTS Poisons. 



1. Arsenate of Lead 



Arsenate of lead 2 to 3 pounds 



Water, or Bordeaux, or lime-sulfur 50 gallons 



Many experiments have shown that well-made arsenate 

 of lead is much the safest of all available arsenical poisons. 

 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 upon the market, the grower should be 

 careful to purchase from reliable firms. 



2. Wet Paris Green- 

 Paris green J pound 



Lime pound 



Water 50 gallons 



If the above amount of Paris green is to be used with 50 

 gallons of Bordeaux mixture the half pound of lime would 

 be omitted.
