The second report was the result of a practical field experiment based 

 on the facts discovered by the earlier investigations. The conditions of 

 this field experiment were not as trying or severe as might be desired, 

 and although the results were highly gratifying, yet they did not seem 

 as conclusive as we could wish. Accordingly, the past summer, another 

 field experiment, on a somewhat larger scale, was tried in a part of the- 

 State where the smut of oats has been very destructive. 



The trial was conducted on the farm of Chas. Baker, Noble County. 



The last week in April three acres of oats were sown in three plats, 

 the seed being ti'eated respectively 40, GO and 90 minutes in a solution of 

 one part of commercial formalin to 200 parts of water. The seed was 

 scattered broadcast without drying. Alongside of these areas was sown 

 a field of untreated seeds. All of the seed used was from a previous crop 

 of smutty oats that was very much infested. 



No difference was noted in the time of germination of the several lots, 

 but the treated seeds produced plants that were more uniform and better 

 developed than those from the untreated ones. 



At the time of cutting the difference between the two fields was very 

 .striking. Fully 15 per cent, of the heads of the untreated seeds were 

 smutty, while not one stalk of the plants from the treated seeds showed 

 any signs of smut. The whole experiment was conducted by the owner 

 of the place from directions and material furnished by the department 

 and the results were examined by one of our students. Of the three 

 separate lots of treated seeds the ones soaked for 60 minutes seemed to 

 be the best, and that time is recommended as safe and efl[icient for 

 treatment. Comment on this experiment is unnecessary, and it is hoped 

 that these facts may increase the use of this fungicide to the improvement 

 of our production of oats.
