Pomological Paragraphs 



Pentachl orophenol -treated posts . Dr. David C. Ferree, Ohio Agricul- 

 tural Research and Development Center Wooster, Ohio, suggests that 

 pentachlorophenol -treated posts should be wel 1 -weathered before be- 

 ing used to support apple trees. When pentachlorophenol was applied 

 2-4 weeks before setting the posts beside trees, injury and growth 

 retardation occurred, and in some instances, death of the trees. 

 Varieties appeared to differ in their susceptibility to pentachloro- 

 phenol. He suggests that treated posts be allowed to weather out- 

 doors for a year before being used to support apple trees. - Fruit

A disorder of Quinte ?: In two orchards this past summer, numerous 

 Quinte fruits had purplish blotches on the skin on both the calyx 

 and stem ends of the apple. The nature of the blotches suggested 

 that low calcium was involved with the disorders. However, analy- 

 ses of a limited number of blotched and non-blotched apples by Dr. 

 Mack Drake showed that the peel calcium was low in both normal and 

 blotched fruit. We would appreciate knowing if blotching of Quinte 

 has been observed by other growers. Also, we have observed that 

 cracking at the stem-end of the fruit appears to be a weakness of 

 Quinte.
