Total grower contribution to the IPM program was $9,500 in 



1982, up from $8,500 in 1981. This money was placed in an Extension 



Activity Account earmarked for Apple IPM program uses (scout sala- 

 ries , etc . ) . 



We would like to extend special thanks to Mr. David Chandler, 

 Meadowbrook Orchards for his generous donation of a 1975 Buick sta- 

 tion wagon for IPM use. The addition of this fine vehicle should 

 enable us to extend the useful life of other IPM vehicles previously 

 donated by the Massachusetts Fruit Growers Association. 



The extent of grower financial support of the Apple IPM pro- 

 gram has been commendable and will serve as a standard by which to 

 gauge levels of support of new IPM projects serving other commodity 

 groups in the state. 



On behalf of all IPM program staff past and present, we wish to 

 express our sincere appreciation for the support and cooperation our 

 pilot program has received. 



Sampling methods . 



We have discussed our monitoring techniques in previous issues 

 of Fruit Notes . One major addition to these techniques was continued 

 field testing of a visual trap for Tentiform leafminer. As we report- 

 ed in 1981, preliminary results are encouraging. These results will 

 be discussed in a later issue of Fruit Notes . 



Degree of cooperation with IPM specialist advising . 



The extent of grower cooperation with specialist spray recommend- 

 ations was excellent in 1982, averaging 831 cooperation (range 43 - 

 100%). While this is somewhat lower than last year when cooperation 

 averaged 891, in 1981 only 11% of IPM blocks (4 36 blocks) com- 

 pletely followed specialist advising, but in 1982, 42% of IPM blocks 

 (15 out of 36) completely implemented specialist recommendations. 



Such blocks had substantially lower harvest injury in spite of 

 fewer insecticide spray applications when compared to all partial co- 

 operator IPM blocks (Table 1).
