Local repair of bonded structure damage from mechanical sources (bird-strike, equipment impact, etc.) can either be bonded or mechanically fastened patches. In general it is more likely that sandwich structure is repaired using bonded patches because of the limited compression capability of sandwich structure and the risk of introducing water into the honeycomb from penetrating fasteners. 

May require removal and destruction of infected plants. Incineration of impacted fields may be required. Consult local/state agricultural assistance office. Many fungi are easily spread by mechanical vectors (e.g., farm implements, track out, running water) and extreme care must be taken to avoid further contamination. Wear disposable protective coverall, disposable boot covers, and disposable gloves. Insects may also act as mechanical vectors for some plant fungi and, if appropriate, response activities must also include efforts to contain and eliminate these vectors.
