In the treatment of onion smut only enough liquid need fall to 

 cover the seed and moisten a little of the surrounding soil. 



Very satisfactory results have been noted from the use of the for- 

 malin drip in this state. Some land so infested with the smut as to 

 make it impossible to grow profitable crops of onions has produced 

 clean crops after treatment by this method. In one case the smut 

 was so severe that the land had to be abandoned, but it now rents 

 for $50.00 an acre as onion land. The apparatus can easily be made 

 up by any local plumber, and on the whole the formalin treatment 

 constitutes one of the most effective methods for the control of onion 

 smut, and has resulted in saving many thousands of dollars each year 

 to onion growers.
