COMBATING APPLE SCAB 



Spraying and Dusting Experiments 



IN 1922 



By WEBSTER S. KROUT 



The scab fungus of the apple affects seriously the Mcintosh Red, par- 

 ticularly as it is grown in the eastern apple region of the State. Nowhere 

 in the State has scab yielded completely to the protective spraying and 

 dusting methods commonly followed by apple growers. The Experiment 

 Station started work on disease control in the fall of 1920. The outstanding 

 fact to date is that of a high degree of control even in spite of adverse 

 weather conditions. This bulletin gives the record of the 1922 operations, 

 together with concise recommendations for protective treatment against 

 the disease.
