SLEEPING DISEASE OF TOMATO 265 



depth of a foot. This should be done about six weeks 

 in advance of planting or the application may be made 

 in autumn. In the case of soil for potting, air-slaked 

 lime mixed with an equal proportion of soot by 

 measure may be used at the rate of one per cent. 

 Where pots are to be placed the ground should be 

 well dressed with quick lime. 



The use of basic cinder phosphate has also been tried 

 advantageously, especially with kainit : two pounds of 

 basic cinder phosphate and three quarters of a pound of 

 kainit per square yard, digging on in the autumn and 

 forking over again before planting. In the case of 

 soil for potting, the mixture may be added to about 

 nine cubic feet, or spread the compost about a foot in 

 depth and sprinkle on it the two and three quarter 

 pounds of mixture per square yard and mix well. 



Though the disease has not been traced to the seed, 

 it is not wise to use that obtained from diseased plants, 

 and even that from a neighbourhood where the disease 

 prevails cannot be safely used, for apart from germs 

 there is greater susceptibility to disease. 



It is needless to insist that the plants should be 

 removed and burned on the appearance of the first 

 symptoms of the disease, and the soil dressed and 

 thoroughly mixed with quick lime.
