Experiments with Onion "Smut" (Urocystis cepulae Frost). 



Six four foot rows were treated with 4, 5, 6, 7, 8, 9 and 12 

 grams S. of I. respectively, applied directly in the row. The 12 

 grams did not hinder germination perceptibly, and appeared to 

 decrease the number of smutted plants decidedly. In another 

 place in the same Bulletin, the Author says Sulphate of Iron 

 may be discarded.

Experiments made with Triticum vulgare, Zea Mais, Avena 

 elatior and orientalis, Pisum sativum, Medicago sativa, Trifol- 

 inm pratense. 



The germination is injuriously affected and seed did not germi- 

 nate in a 2 per cent solution. Oats most resistant. 



Young plants are injured by S. of I. (by long action). The 

 roots die in a 0.005 P er cent solution. 



Grown, strong plants die on the fourth day when in 1-2 per 

 cent solution. Grew, but with signs of distress in 0.1-05 per 

 cent solution. 



Raygrass lived for eleven days in a 0.1 per cent solution.
