Abstract:

Fungicide-treated shoeboard and leatherboard footwear counter materials with suitable controls were evaluated for rot-resistance in the soil burial test. Copper 8-quinolinolate, sodium pentachlorophenate and zinc dimethyldithiocarbamate were the fungicides evaluated for use in shoeboard. Paranitrophenol was evaluated for use in leatherboard. Copper 8-quinolinolate 0.5 to 1.0 percent and sodium pentachlorophenate 1 to 2 percent effectively inhibited microbiological degradation of shoeboard which is basically a susceptible composite material. However, the effectiveness of sodium pentachlorophenate is not relevant because of toxicity considerations and because it was incompatible with the shoeboard matrix, showing a tendency to tender the cellulosic portion of the shoeboard and migrate to the surface. Leatherboard, because of its inherent resistance to microbiological deterioration, is a more desirable counter material from the biological point of view than fungicide-treated shoeboard which will eventually deteriorate after a suitable induction period.
