CONFERENCE ON SPRAYING OF FRUIT TREES. 



351 



Uses. — This wash cleanses trees of moss and lichens : it also is 

 fungicidal, and is of value where apple scab occurs on the wood. The 

 mussel scale ova are destroyed, as well as oyster-shell bark lice. The 

 copper sulphate is not necessary except where apple scab occurs on wood, 

 and thus should have its place taken by the cheaper iron sulphate if the 

 scab is not present. 



Time of Application. — Any time between November and February. 



Lime and Salt Wash. 



This wash has come into use mainly on account of its tending more 

 than anything else to prevent the damage dona by the apple-sucker.

Preparation. — Get fresh lime of the best possible quality (flare lime 

 is found to be the best) and let it slake gradually, and then mix it with 

 the water in which the salt has been dissolved, and strain through a 

 fine sieve or sacking into another receptacle. Waterglass has been 

 added to make the wash hold better on the trees, but it is not essential, 

 and does not always seem to have sufificent effect to make the extra cost 

 worth while. 



If it or the soda is added it should be put in the strained wash, having 

 been previously dissolved in water. 



Uses. — For the prevention of hatching of the eggs of apple- sucker, 

 plum aphis, and mussel scale, and for cleansing the trees of moss, 

 lichens, &c. 



Time of Application. — The end of February until the beginning of 

 April. Spraying should cease as soon as the buds open.
