the best preventives. Destroy all infested plants, 

 being sure to get the maggots when pulling them 

 up. The remaining plants should be treated with a 

 gill of strong caustic lime water, or solution of - 

 muriate of potash poured about the root of each 

 plant, first removing an inch or so of earth. In place 

 of these solutions carbolic acid emxulsion is some- 

 times used; or eight to ten drops of bisulphide of 

 carbon are dropped into a hole made near the roots 

 with the dibber and then covered in. Extra stimu- 

 lation, as directed for Club-root, will help carry the 

 plants through.

 be trapped under boards and by early vines. The 

 young bugs, or "sap-sucking nymphs," are the ones

 or kerosene emulsion will kill them. 



White-fuy: — This is the most troublesome under
