FORMALIN TREATMENT FOR OAT SMUT 61c 



ever, as was previously menti d, the yields are 



not a reliable criterion in such short terra experi- 

 ments. 



E. Solution — One pint formalin to thirty gallons of water. 



1. From the germination tests all treatments are safe. 



2. In the field work the low yield assigned to a pari 



of the pints was due Largely to Lodging prior to 

 ripening. Otherwise, no particular difference was 

 observed between these plots and the checks. 



F. Si 1 ut ii ii — One pint formalin to forty gallons of water. 



1. The vitality of the oats was not injured by any of 



the treatments. 



2. The field records show that the crop yielded some- 



what better than the cheeks. This is partly ac- 

 counted for in that the soil in a portion of the 

 series had received a heavier dressing of manure 

 two years previous. No increased yields should 

 l»e ascribed to the treatments. 



Notes on Amount of Solution per Bushel. 



1. When one pint per bushel was used, considerable hand- 

 ling made the oats damp but not wet. They were ready to plant 

 after the treatment. Oats were practically dry at the end of 



twelve hours. 



2. Two pints per bushel moistened the oats, but did not 

 wet them to any marked degree. The oats were ready to 

 after the treatment and were dry at the end of twelve hours. 



3. With four pints per bushel the oats seemed to be covered 

 with a film of solution, but there was no excess solution left 

 after a thorough shovelling. The oats swelled considerably. At 

 the end of twelve hours the pile was only slightly damp. 



4. Six pints made the oats very wet. only a comparatively 



small amount of solution was left over after a thorough mix- 

 ing. 



5. Eight pints caused the oats to drip, a small amount of 

 solution remaining after the oats were well mixed: evidently 

 being more than could he taken up by the oats.
