These will ripen sufficiently to germinate 
in ten days after the opening of the flowers.

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.
