Effective phosphine fumigation depends on the maintenance of sufficiently gas‐tight conditions. The German Agency for Technical Cooperation (GTZ) has started a programme to ensure that suitable gas‐tight, mechanically resistant foils are available for developing countries. Six foils were tested for gas‐tightness under laboratory conditions before and after repeated twisting in a special apparatus. Much the best was Waloplast Combi, which was completely impermeable and not damaged by twisting, though its thinness makes it liable to splitting by sharp edges and it would be better combined with mechanically resistant materials. The other foils mostly gave similar moderately good gas‐tightness, but varied considerably in their susceptibility to damage.
