Summary of Res ul ts . 



Intensive weekly scouting and grower advisement 

 in 18 good-cooperator IPM blocks, resulted in a 

 savings in insecticide, aphicide, and miticide 

 spray use (dosage equivalents) of 40%, 97% and 

 56% respectively. Permanent type fruit injury 

 was 8% lower in IPM than Check blocks. Cost 

 benefit analysis indicated an average net savings 

 from IPM of $93.37 per acre. 



Compared with previous years, 1980, the third year of 

 operation for the Massachusetts apple IPM program, was char- 

 acterized by significant changes in number o£ orchards scouted, 

 grower financial support, grower participation in orchard 

 scouting and sampling methodology ^. 



Program objectives continue to be: 1) to aid in the pro- 

 duction of high yields of high quality fruit while reducing the 

 amount of pesticide usage; and 2) to encourage the use of spray 

 materials which allow for survival of beneficial predators and 

 parasites .

Reduced spray programs on apples have been discussed in previous 



issues of Fruit Notes [41(1), 41(2), 41(3) and 43(3)1], and our 



1978 and 1979 results were summarized in Fruit Notes 44(1) and 



44(6).]
