THE APPI^ SCAB SITUATION TO DATE 



This has no doubt been one of the most favorable seasons in many 

 years for scab infections. Up to the present (May 21), there have been eight 

 general infection periods in the State since apple trees v/ere in the late de- 

 layed dormant stage of fruit bud development. Not only have rainy periods 

 been niomerous, but the total precipitation has been excessive. For example, 

 the total rainfall in Amherst during April v;as 5.43 inches, or 2.08 inches 

 above normal; and for May (up to the 21st), 5,97 inches, which represents 2.37 

 inches above normal for the entire month. The following are the dates of apple 

 scab infection periods for unsprayed Mcintosh trees at Amherst and the dates 

 when the scab spots appeared on the new leaves j
