RESULTS OF A TELEPHONE SURVEY OF EXTENSION IPM PROGRAM IMPACTS 

 ON COMMERCIAL APPLE GROWERS IN MASSACHUSETTS: PART II

Introduction 



In an earlier volume of Fru i t Notes (Spring, 1986, Vol. 51, No. 2), we 

 reported our initial analysis of a telephone survey administered to a sample 

 of Massachusetts apple growers which was performed earlier in 1986. That 

 article explained that the survey attempted to determine what impacts the 

 University of Massachusetts Extension IPM Program has had on apple grower 

 attitudes and pest management practices. Persons interested in details of 

 the methods used to design the questionnaire, select a sample, or administer 

 and analyze the data are referred to this earlier article. 



A complete analysis of survey results will be published at a later date 

 as part of a national impact survey of IPM programs being conducted by 

 various states under the leadership of Virginia Polytechnic Institute and 

 State University (VPI). We wish to acknowledge the substantial assistance 

 provided us by Drs. E. Rajotte and R. Kazmierczak of VPI.
