5p6 SPECIAL PLANT PATHOLOGY 



The disease may be controlled by removing the smutted plants 

 from the field and destroying them and also by a rotation of crops. 



Fig. i8o. — Corn smut on tassels of sweet corn. {After Jackson, F. S., Bull. 83, Del. 

 Coll. Agric. Exper. Slat., December, 1908.) 



As the fungus may infect the adult plant, the treatment of the seed 

 corn with fungicides has been unsuccessful. Rotation of crops also 

 assists in keeping smut in check.
