soils. Enhancement of the fungitoxicity of cu- 

 pric ions by SA may permit large reductions 

 in the total amount of Cu applied for plant 

 disease management, thereby reducing or 

 eliminating problems from Cu accumulation. 

 Evaluation of these possibilities requires fur- 

 ther testing of the effects of SA and other ma- 

 terials on the outcomes of plant-pathogen in- 

 teractions in controlled and field environ- 

 ments. 



ACKNOWLEDGMENTS 



We gratefully acknowledge the financial 

 support of two mini-grants from the Bluegrass 

 Community and Technical College, 470 Coo- 

 per Drive, Lexington, KY 40506-0235, without 

 which our research would not have been pos- 

 sible. We also give thanks to Dr. William Witt, 

 Department of Agronomy, University of Ken- 

 tucky, Lexington, KY 40506, for his gift of 

 Gramoxone (PQ), and to Dr. Lisa Vaillancourt, 

 Department of Plant Pathology, University of 

 Kentucky, Lexington, Kentucky 40506, who 

 provided us with a culture of CoUetotrichum 

 graimnicola (CG).
