USEFUL FUNGICIDES. 



The most useful liquids for spraying trees which are in- 

 fected, or threatened with infection, by fungoid diseases, 

 are: — 



Bordeaux Mixture. — Dissolve, separately, in wooden tubs, 

 two pounds of copper sulphate in five gallons of water and 

 five pounds of fresh lime, previously slaked, in the same 

 amount of. water. Mix the two, and keep stirred while 

 spraying. 



Lime-Sulphup Wash. — Quicklime, four pounds; flowers 

 of sulphur, four pounds; water, twenty-five gallons. Slake 

 the lime in a barrel by pouring on it one gallon of water, stir 

 in the sulphur, adding enough water to make a paste; when 

 the boiling ceases, pour in the rest of the water, and strain 

 through a fine sieve before using. Excellent for plants whose 

 foliage is likely to be damaged by Bordeaux mixture. 



Liver of Sulphor. — Dissolve half an ounce in one gallon 

 of water. The addition of a little soft soap will make it more 

 adhesive. It blackens paint. Like the next, a simple, cheap, 

 and easily-made fungicide, excellent for mild forms of dis- 

 ease. 



Potash Permanganate. — Dissolve just sufficient to make 

 the water a pale rose colour. 



Wisley Lacto-Burgundy Mixture. — The ingredients are: — 

 Copper sulphate, nine and three-quart cm- ounces; sodium 

 carbonate, eleven ounces; milk, three-quarters of a pint; and 

 water, three gallons. Dissolve the copper sulphate in half 

 the water in a wooden tub; treat the sodium carbonate in the 

 Kaine way; mix the two and add the milk.

It is impossible to arrange fungoid diseases in the same 

 uay as injurious insects, Ixnause the parts wliich show the 

 effects may not be those which are attacked. I'or instance,
