Ascospores of 4 species of Eurotiales were tested and showed clear variations in sensitivity. The most resilient species, T. macrosporus and Pae. variotii (=B. spectabilis) survive 75, but not 200 ppm chlorine dioxide solution treatments. These species were able to survive 75 ppm iodine solution treatments, but relatively low amounts of ascospores (100-1000 spores) could be inactivated after 16 h of treatment. Inactivated spores did not show any sign of germination after 7 days following treatment on growth medium. As judged by microscopy, iodine inactivation resulted in visibly distorted ascospores. For the interpretation of results, the state of dormancy or activation of ascospores is highly important.",
