inoculum available for infection in the spring. This 

 information is being incorporated into research efforts 

 to be conducted in the future. 



Applied Studies 



The strawberry IPM program has secured 2 acres 

 of land at the University research farm in South Deer- 

 field for applied studies of pest management practices. 

 Currently, studies of fumigation materials at different 

 rates and non-fumigant cultural practices are in prog- 

 ress. There is little doubt that fumigation provides 

 tremendous production benefits. However, its eco- 

 nomic and ecological costs are generally high. Alterna- 

 tively, certain cover corps have allelopathic qualities 

 which reduce pathogens, nematodes, and the viability 

 of weed seeds. They might also have some direct 

 economic value to the grower, as with Sude.x (a Sudan 

 X sorghum hybrid which is now used by some growers 

 as winter mulch) or pumpkins (which have been stud- 

 ied for their allelopathic qualities related to black root 

 rot control in strawberries). This work illustrates the 

 value of cultural practices in IPM systems. Additional 

 studies for improved and innovative management of 

 Botiytis gray mold, tarnished plant bug, and two- 

 spotted spider mites are planned for 1989.
