REMEDIES. 108 



Sulphate of copper i lb. 



Ammonia 2 qts. 



Soft Water 6 qts. 



To one pint of this mixture add two quarts of Ammonia, 

 stirred in a barrel of water and the plants should be well syringed 

 every two weeks on a clear day. 



The following formulas have been experimented with, giving 

 substantially the same beneficial results: 



The liquid Bordeaux mixture consists of 



Copper Sulphate 6 lbs. 



Quick Lime 5 lbs. 



Water 22 gals. 



Chloride Copper 3 oz. 



Water 22 gals. 



Sulphide of Potassium 2 oz. 



Water 22 gals. 



Arsenical formula for Rust: 



Arsenous Acid 616 grains. 



Carbonate of Potash 1236 ounces. 



Water 5 ounces. 



Heat to make the solution. One ounce to a gallon of water, 

 used as a spray. It is asserted this will not only check but 

 exterminate Rust. 



Mr. C. W. Ward's treatment is prophylactic and effective, I 

 quote his own language: 



Dipping. — All young plants are immersed in the liquid 

 Bordeaux mixture when set in the open ground. x\ll mature 

 plants are immersed (tops on]y, not the roots) in the same mix- 

 ture when benched in. 



Spraying. — All young plants are sprayed with either the 

 liquid Bordeaux or ammonia solution once in two weeks while 

 under glass, and all field plants are sprayed the same in field. 



FosTiTE — Under glass all plant houses are blown full of 

 Fostite in a fine cloud, every dark, cloudy day.
