A Report on the 1983 Apple IPM Program 

 W.M. Coli-^, R.J. Prokopy-^, and W.J. Manning' 



1983 was a year of transition for Apple IPM in Massachusetts, during 

 which program emphasis shifted from providing scouting and pest management 

 advisory services for a limited number of growers toward a stronger 

 educational and information transfer effort for all the state's growers as 

 well as support of private sector IPM implementation. 



Grower interest in and support of IPM continued to be excellent, with 

 informal surveys indicating that over 2/3 of the state's total apple 

 acreage is presently under some form of integrated management (e.g. private 

 sector scout/consultants, grower scouting, careful attention to proper 

 timing of pesticide application, or selection and use of IPM-compatible 

 pesticides). In FY 1983, growers contributed $3200 toward the continuation 

 of the program and apple IPM specialist position — a substantial 

 committment when one considers that many of these same growers also paid 

 @$20/acre for private scout/consultant services. Further, a mechanism was 

 established to lease to private parties 9 hygrothermograph units. 



Extension faculty and professional staff conducted or participated in 



12 IPM training sessions (usable for pesticide certification credits) (4 in 



each of the three major fruit-growing regions of the state.)
