hope to be armed with more information to handle the next one, whenever it may 

 occur. We are involved currently with assessing injury levels in heavily- 

 infested blocks in order to determine whether PLH injury affects premature 

 drop, fruit size or color, or fruit set the following spring.

ERRATUH 



A Report of the 1986 Massachusetts Apple IPM Program 



William M. Coli, Daniel R. Cooley, Kathleen Leahy, and Ronald J. Prokopy 



University of Massachusetts 



In the article on the Apple IPM Program results published in the Spring 

 issue of Fruit Notes [52( 2) : 1 1-16] , we neglected to acknowledge the 

 contribution of the Regional Fruit Specialists, Jim Williams in particular, to 

 the IPM program. In addition to being responsible for sending the twice-weekly 

 Pest Alert Messages, the Regional Specialists have shared information gathered 

 from their orchard visits with us. Jim also has done regular, weekly IPM 

 scouting in at least one orchard for the past 4 seasons, and his assistance has 

 been of great value to the IPM Program, allowing us to extend our monitoring to 

 parts of the state which University-based scouts are unable to visit regularly. 

 We regret having omitted Jim's name, as well as Dom Marini and Karen Hauschild, 

 from the list of credits for all who have helped the program.

Early season apples are often thought of as second-rate fruit, stop-gaps 

 until the real show begins with Mcintosh. Redfree may not change the attitude 

 we have about Mcintosh, but it may offer an excellent opportunity for high- 

 quality, early-season fruit. The disease resistant planting at the 

 Horticultural Research Center, Belchertown, MA, has two Redfree trees, both of 

 which fruited heavily this year. The fruit were ready to pick August 10, making 

 it harvestable at about the same time as Jersey Mac and approximately 1 week 

 earlier than Paulared. When the fruit were harvested, most had approximately
