2. Paris Green (Wet). 



Parts. Per Barrel. 



Paris green, .... 1 pound f pound. 



Quick lime, .... 2 pounds. | pound. 

 Water, 150 gallons. 50 gallons. 



Slake the lime, sprinkling in the Paris green gradually, then 

 add the rest of the water. Do not let it stand long before 

 using. For the peach and other plants with tender leaves use 

 23^ ounces Paris green and 5 ounces of quick lime to 50 gallons 

 of water, instead of the amounts given above. Keep the mix- 

 ture well stirred while spraying. 



Paris green is coming into disfavor, being much more likely 

 to burn the leaves than arsenate of lead. 



3. Arsenate of Lead. 



Arsenate of lead can be made by the user, but with many 

 good brands on the market, and difficulty in getting the ma- 

 terials from which to make it, it is usually better to buy it. 

 It can be obtained either as a paste or dry, but as a general 

 rule the paste seems to have thus far given slightly better 

 satisfaction. It must be thoroughly mixed with the amount of 

 water called for by the directions sent with it, but can be used 

 stronger if necessary. In general, 3 pounds to 50 gallons of 

 water is the best strength. 



Contact Insecticides (for Sucking Insects — Plant Lice, 



Scales, etc.). 



4. Kerosene Emulsion. 



Any good hard soap, shaved fine, ^ pound. 

 Soft water, 1 gallon. 

 Kerosene, 2 gallons. 



Dissolve the soap in the water, which should be hot; then 

 remove from the fire, add the kerosene and churn with a hand 

 spray pump, turning the nozzle into the container, continuing 

 the churning until the material gets thick and goes hard through 

 the pump. This is the stock material. For use against plant 

 lice, mix 1 part of this stock with 9 parts of water, and spray.
