PIRATE 8 
The control of the rosette disease by the use of resistant varieties and by very late 
fall planting. J 
A—a. Healthy wheat plants grown from specially selected seed from resistant 
plants of Harvest Queen (Salzer s Prizetaker) grown on infested land; 6, diseased 
wheat of same age and of same variety grown from unselected seed. Plot b showed 
90 to 95 per cent of rosette disease. 
_B.—a, Good stand obtained on uniformly infested soil by very late fall sowing 
This plot was sown November 18,1919, and plants did not emerge until the following 
spnng; b , thin stand of dwarfed wheat, heavily infected with the rosette disease 
This plot was sown October 16, 1919, and the plants emerged in the fall. The thin 
stand is due in part to winter injury, but the dwarfing is caused by the rosette 
disease.
