COMBATING APPLL SCAB 



Spraying and Dusting Experiments 

 IN 1922 



By WEBSTER S. KROUT 



The scab fungus of the apple affects seriously the Mcintosh 

 Red, particularly as it is grown in the eastern apple region 

 of the State. Nowhere in the State has scab yielded com- 

 pletely 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.
