Means of control 



Sow clean seed. Cleanse the Daisy-cursed 

 meadow with a short rotation of other 

 crops. Though perennial, the roots are 

 shallow and are turned out and killed by the 

 plow. Mow infested meadows as soon as 

 the first flowers appear, in order that the 

 seeds may not have time to ripen. Fre- 

 quently cut and salt the plants of the 

 pasture, which will induce the stock to 

 feed on the leaf-tufts and aid in their de- 

 struction. Roadside and waste-land plants 

 should be cut before seed development, or 

 should even be hoed out, for the benefit of 

 adjacent ground.

 spoil the flavor of milk and butter.
