 LIME-SULPHUR SPRAY SOLUTION 



Object: To make lime-sulphur solution. 



Material : 36 pounds of lump lime; 80 pounds of sulphur; 

 iron kettle; and water. 



Method: Slack the lime in the iron kettle and add 

 enough water to make 50 gallons. Put a stick in the kettle 

 and cut a notch in the stick to mark the height of the water. 

 When the water begins to boil add the sulphur and stir until 

 all the sulphur goes into solution, which is usually in about 

 three quarters of an hour. Pour water in the kettle until 

 it reaches the notch on the stick. This is the stock solution. 



As a dormant spray, use 1 gallon of the stock solution 

 to 8 gallons of water. As a summer spray, use 1 gallon of 

 the stock solution to 30 gallons of water.
