270 APPENDIX. 



LIME-SULPHUR WASH 

 The following formula may be used : 



Unslaked lime 20 pounds 



Flowers of sulphur 15 pounds 



Water to make 45 to 50 gallons 



The lime should be slaked in a small quantity of water. The 

 sulphur should be mixed into a stiff paste and added to the lime 

 which has been slaked. The mixture should then be boiled for 

 an hour, after which the full amount of cold water can be added, 

 The mixture should be strained and used at once. This mixture, 

 which is much used for scale insects, should be applied just be- 

 fore the buds open. 



SELF-BOILED LIME-SULPHUR MIXTURE 



Sulphur 10 pounds 



Lime 10 pounds 



Water 50 gallons 



Place the lime in a barrel and add enough water to start it 

 slaking and to keep the sulphur off the bottom of the barrel. 

 Add the sulphur, which should first be worked through a sieve 

 to break up the lumps, and finally add enough water to slake 

 the lime into a paste. Considerable stirring is necessary to pre- 

 vent caking at the bottom. After the violent boiling which ac- 

 companies the slaking of the lime is over, the mixture should be 

 diluted ready for spraying, or at least enough cold water added to 

 stop the cooking. The mixture should then be strained to remove 

 the coarse particles of lime, but all of the sulphur should be 

 worked through the sieve. 



This mixture is not injurious to peach foliage. 



SULPHUR AND RESIN SOLUTION. 



Sulphur (flowers or flour) 16 pounds 



Resin (finely powdered) Yz pound 



Caustic soda (powdered) 10 pounds 



Water to make 6 gallons 



(1) Place the sulphur and the resin, thoroughly mixed, in a 

 barrel and make a thick paste by adding about 3 quarts 

 of water. 



(2) Stir in the caustic soda. After several minutes the mass 

 will boil, turning a reddish brown, and should be stirred 

 thoroughly. 



(3) After boiling has ceased add about 2 gallons of water and 



pour off the liquid into another vessel. Then add water 

 to make 6 gallons. This form of stock solution should be 

 used at the rate of 1 gallon to 50 of water for spraying 

 most plants and for soaking seeds.
