CORN SMUT 



1. In your neighborhood, is Corn Smut more injurious to sweet corn 

 than to field corn ? Is it more destructive in gardens where sweet corn 

 is planted in the same place year after year than in gardens where the 

 sweet corn is rotated with other crops? 



2. At what time do the first black spores develop on the smutted 

 ears ? 



3. Do the people of your locality take pains to cut out and burn the 

 diseased plants ? 



4. Make a drawing of a diseased ear of corn. If there is a com- 

 pound microscope in school, make sketches of the spores as seen with a 

 high-power objective.
