CABBAGE 

 I^ICE 



The lice which become so abundant on cab- 

 bage, cauliflower, mustard and like plants are 

 quite difficult to combat. Kerosene emulsion 

 does not effect them, because they are covered 

 with powder which keeps the spray from wetting 

 them. To be of use a spray must be applied 

 with such force that it will knock the lice off the 

 plants. A spray of hot water is sometimes ef- 

 fectual and the user can become so expert that he 

 can use water hot enough to kill the lice without 

 injuring the plants. A very fine forced spray 

 of pure coal oil may do the work. The prob- 

 lems of dealing with such lice will have to be 

 worked out by each grower.

CHINCH 



BUGS 



The true chinch bug has never been destruc- 

 tive to crops under irrigation. There are places, 

 however, where the false chinch bug, which looks 

 very much like the ordinary form, becomes quite 

 destructive. In places they destroy crops of beets 

 and may attack many other crops. The kerosene 

 emulsion spray is the only thing which has been 

 suggested outside of crop management, and it 

 may be said that there is no effective remedy.
