CONTROL 



This pest is rapidly gaining ground 

 in Xorth Carolina. Imported some 

 years ago in clover and other seeds 

 from Europe, it has now taken such 

 hold in some sections of the State that 

 its eradication will require rather he- 

 roic measures. Like chickweed, it ac- 

 quires its principal growth in early 

 spring when other plants are dormant, 

 and, its seeds being inconspicuous, re- 

 seeds the land profusely before one is 

 aware of it. 



Methods of eradication are about the 

 same for this plant as for chickweed. 

 Keep it from seeding, and sow only 

 good, clean seed.
