eradication 

 The failure of many farmers to make use of this vahiable 

 legume has been largely on account of the fear that sweet clover 

 cannot be eradicated from their farms when once started. The 

 biennial nature of the plant makes the problem of eradication very 

 easy. The plant does not give trouble in clean-cultivated or inter- 

 tilled crops, as the cultivation readily kills young plants. Its 

 appearance in meadows or grain fields should give no alarm, as 

 mowing will serve to kill the sweet clover. This crop is seeded 

 annually on thousands of acres of land in many sections of the 

 country, and not a single case has been noted where it has become 

 aggressive, with the possible exception of irrigated land in the 

 West. In this region it becomes a pest at times along irrigation 

 ditches.
