INSECTICIDES 

 Direct Poisons for Chewing or Biting Insects 



1. Arsenite of Copper, Green Arsenoid or Green Arsenite 



(a) Strong Mixture: i ounce to 6 gallons of 



water. Use this only on very strong and 

 hardy vegetation such as potato plants, 

 or for insects very hard to kill, such as 

 the cankerworm. 



(b) Medium Mixture: i ounce to 9 gallons of 



water. Use this for all general spraying; 

 do not use on extremely delicate and ten- 

 der plants. 



(c) Dilute Mixture: i ounce to 15 gallons of 



water. Use this on peach, apricot, 

 tender plums and all tender vegetation. 



Mix the poison into a thin paste and add 

 twice as much quicklime as poison — more 

 will do no harm, even up to three times as 

 much. The lime takes up the * ' free arsenic ' ' 

 which is the substance that scalds the plants. 

 After mixing, strain into the spray tank, 

 rinsing and pulverizing all of the solid 

 matter through the strainer thoroughly; 

 then add the necessary amount of water. 

 This is advised instead of Paris Green.
