SCAB SPORES A BNORl,iAL LY EARLY 



At this date (ilarch 27), with apple buds still dormant, the 

 development of scab ascospores in i!assachusetts is as far advanced 

 as it ordinarily is at the ^^reen-tip fruit bud stage. In the oldest 

 perithecia mature spores are abundant. This situation emphasizes (1) 

 'ihe need to reduce the heavj'" scab carryover with a floor spray of 

 dinitro and (2) the need for extra care in keeping susceptible varieties 

 protected against scab, from early Pre-Pink onv/ard.
