The object of this preparation is to obtain an adhesive material 

 which will cause the poison to adhere to smooth leaves. It has been 

 highly recommended by the New York State (Geneva) Experiment 

 Station. 



The stock solution No. 15 can also be used in making the resin- 

 Bordeaux mixture by taking two gallons and adding it to 10 gallons 

 of water. This is mixed with 40 gallons of Bordeaux. 



16 LIME-SULFUR WASH. 



Fresh stone lime, 20 to 22 pounds. 



Flowers of sulfur or sulfur flour, 18 to 20 pounds. 



Water, 45 to 50 gallons. 

 Slake the lime with some of the water in a large iron kettle, 

 sprinkling in the sulfur gradually. Start a fire under the kettle to 

 continue the heat begun by the slaking lime, and boil till the mixture 

 becomes dark orange in color, adding water till 35 or 40 gallons are 

 in the kettle. Boiling should probably take from 40 minutes to an 

 hour. Stir frequently and a successfully prepared lot should have 

 little sediment on the bottom when the boiling is finished. Strain 

 through a fine meshed strainer into the spray pump, adding the rest of 

 the water, and spray while warm. It is generally better to use only 

 the freshly prepared wash, though good results have sometimes been 

 obtained with it when it has stood over night. This should not be 

 applied to trees after the leaves have opened. 



17 CARBOLIC ACID i:MULSION. 



Hard soap shaved fine, i pound. 



Water, i gallon. 



Crude carbolic acid, i pint. 

 Dissolve the soap in boiling water ; add the carbolic acid and churn

 water. 



18 HELLEBORE. 

 Hellebore, i ounce. 

 Water, i to 2 gallons. 



Steep the hellebore in a pint of water and gradually add the rest 

 of the water. Hellebore may also be dusted over the plants, either 

 pure or mixed with flour or plaster.
