Twenty‐five wound dressing compounds were screened for control ofChondrostereum purpureuminfection of pruning wounds on willows (Salixspp.), apples (Malus domestica), and golden queen peaches (Prunus persica). None were completely effective but products giving best control were: Garrison; Shell pruning grease; and cyproconazole + iodocarb.C. purpureuminfection with Nectec Liquid and copper oxychloride treatments was significantly (P >0.05) greater than the control indicating a reduced host resistance either directly or by elimination of antagonists. Application of the biocontrol fungusTrichoderma virideto wounds failed to give significant (P >0.05) control ofC. purpureuminfection in willows and peaches. Scanning electron microscopy of field exposed wound dressings revealed considerable differences in film integrity with fissures, pores, and fungal hyphae evident.
