Strawberries resistant to tarnished plant 

 bug? Although it may sound too good to be true, 

 research at the University of Maine suggests 

 that some strawberry cultivars may be consid- 

 erably less susceptible to tarnished plant bug 

 injury than others. Twenty strawberry culti- 

 vars, all currently available from commercial 



nurseries, were grown in small, replicated plots 

 which received reduced insecticide applications 

 for two seasons. While some cultivars had more 

 than half of their crop ruined by tarnished plant 

 bug (seedy ends or "buttoning"), others showed 

 very little damage and high marketable yields.
