 re-planted in a new grove. 



4. .\\oid highly nitrogenous fertilisers in diseased groves, 

 using preferably nitrate of soda or sulphate of ammonia as a 

 >f nitrogen. 



All tools used in infected groves should be cleaned and 

 \vashed with crude carbolic acid before they are used in healthy 

 es. 



Tn setting new groves dead trees should be replaced 

 with trees budded on resistant stock. 



7. Avoid excessive and deep cultivation in diseased groves. 

 Injuries to the roots, such as are often caused by deep plough- 

 ing, seem to greatly favour the spread of the disease.
