- Figure 1.
Differences in degradation of sapwood by decay in cross-sectional disk samples removed from the untreated bole section (AC2) and one treated with permethrin insecticide (AT2). The untreated control shows well-defined edges of decay (solid line—decay is clearly recognizable and loss of wood structure evident). In the treated section, most of the stained wood appears sound but its color differs. The dashed line delineates affected from unaffected sound heartwood.
- Figure 2.
Detail showing coast live oak bark surface differences in Monothrum scutellare activity at the borderline between sprayed and unsprayed bark surface. The insets represent 2 m (6.6 ft) long sections: A = unsprayed control stem; B = sprayed stem.
- Figure 3.
The extent of decay in the two 12 m (39.6 ft) long downed boles of Quercus agrifolia, each divided into six equal sections of which the bark surfaces of three sections were treated with permethrin insecticide and the remaining three sections were untreated controls.
