PLANT DISEASES. 



The Loose Smut of Oats. 



The loose smut of oats is found wherever oats are cultivated, and 

 annually causes a great deal of damage. Like most of the loose smuts 

 of grain, the smut fungus matures at about the time the grain is in 

 flower, and is widely distributed during the ripening season, so that the 

 grain, when harvested, is well covered with the spores. Before the seed 

 IS planted, if the grain is sprinkled thoroughly with formalin, 1 pint to 

 30 gallons of water, then allowed to dry, the damage done will be slight. 



The Loose Smut of Wheat. 



Another smut, which attacks wheat, is similar to that of oats. Some- 

 times infection may occur at the time of blossoming. Unlike that of 

 loose smut of oats, means of prevention will consist of treatment of the 

 seed, together with seed selection. Select seed from a field free from 

 smut, and treat the seed by soaking five hours in cold water, and then in 

 water at 129.2° Fahrenheit.
