It is iulrocluced as an impurity in seed of clover, grasses, etc. 



A well developed plant may produce 200,000 seeds in one season. 



Mowing will not control the pest. 



A short rotation with at least two seasons in hoed or cultivated crops 

 will keep the number down. 



The best practice is to spud out every plant the first season they ap- 

 pear and every j^ear thereafter, not allowing them to produce seed. 



If very abundant, plow under before they seed and spud out every 

 plant that appears in succeeding years.
