The Bulletin- 



Yellow Nut Grass. Cyperus escuhntus L. 



A member of the Sedo:G Family. Perennial. Yerv similar to a grass 

 in appearance, but the leaves are arranged in ranks of three at the base, 

 of the flowering stem. Flowers reddish brown, in slender spikelets, which 

 are arranged in a cluster of loose spikes, subtended by an involucre of 



three to six leaves. Xo 

 seeds are produced, and 

 the plant is propagated 

 by small edible tubers 

 ;^v ^ Avhich occur at short in- 



i?^^ ^^if^ tervals along the root- 



stock, and which render 

 the plant so difficult of 

 eradication. Occurs 

 throughout the State in 

 moist ground. August to 

 October. Very abundant 

 eastward. 



CONTROL 



It is rather difficult to 

 control this pest, as it 

 does not need to make 

 seed in order to spread 

 its growtli. The small, 

 brown edible tubers mul- 

 tiply on thei roots and 

 from these tubers new 

 plants come each year. 

 Hogs like the tubers and 

 help keep the plant in 

 check in fields that can 

 be pastured by hogs. 

 "While there is no very 

 effective remedy for this 

 pest known, about the 

 best is thorough drain- 

 age, where the land is in 

 need of drainage, follow- 

 ed by clean and thorough 

 cultivation. Smothering 

 crops will liclp. and an 

 alternation of hay and 

 hoed crops is likely to be 

 found satisfactory.
