We conclude from this first year of experimentation that an 

 alternate middle row spray program in Massachusetts shows promise 

 of effectively controlling the major pests that attack the fruit, 

 even in the face of potentially damaging pest pressure. This 

 effectiveness may stem in part from the adults of these pests 

 moving around the trees with sufficient regularity to contact the 

 sprayed portion. On the other hand, this program seems to be 

 less effective (though still possibly adequately so) against mites 

 and aphids, whose mobility is very limited. Keeping the tree well 

 pruned and the center open should enhance the effectiveness of 

 this program against all pests, particularly mites and aphids. 



In summary, at least 2 more years of field research are 

 necessary before we will be in a position to make any firm recom- 

 mendations as to the cost-benefit value of alternate middle row 

 spray programs in Massachusetts. But the results of this first 

 year of research are encouraging.
