TWO KINDS OF REMEDIES

(1) Arsenate of lead, if in the paste form, is mixed 

 with water in the proportion of 3 pounds of the poison to 

 50 gallons of water. In its dry form 1 pounds of the 

 poison is enough for 50 gallons of water. The materials 

 should be well mixed and strained before spraying. 

 Arsenate of lead by the hundred- 

 weight costs from eight to twelve 



cents a pound. 



(2) Paris green is used with 

 quicklime and water in the follow- 

 ing proportions : 



Paris green \ pound 



Quicklime 1 pound 



Water 50 gallons 



The Paris green is first made into 

 a paste with a little water ; and 

 about a pint of water is addecl to 

 the lime to slake it. The two sub- 

 stances are then put together, some 

 more water added, and the mixture 

 is strained and made up to 50 

 gallons. If quicklime is not readily 

 secured, one fourth pound of the 

 Paris green may be mixed with 50 

 gallons of water. The purpose of the quicklime is to 

 prevent the Paris green from burning the foliage. 



Both insecticides are applied in a fine spray. It is impor- 

 tant that the spray mist touch every part of the plant 

 where the pest is likely to feed. Arsenate of lead is very 

 adhesive, and not easily washed off a plant by rain. It is 

 rapidly taking the place of Paris green for spraying. 

 Farmers often use either one or the other of these insecti- 

 cides in combination with some fungicide (poison for
