“…Statistical analysis showed that this difference is significant. A similar curve, although less pronounced, was obtained by Bollen(1971) for a benomyl-tolerant strain of Penicillium brevicompactum. Because the fungus had a strong tendency to grow superficially on agar supplied with high concentrations of benomyl, it could be argued that the tolerance found in vitro might be due at least partially to a poor diffusion of MBC in the agar.…”

Isolates of Fusarium oxysporum f. sp. tulipae were tested for tolerance to benomyl. Although all isolates were relatively insensitive to benomyl, no tolerance was found. Some isolates, however, became tolerant to benomyl in vitro after prolonged contact with increasingly high concentrations of the compound in the medium. The properties of one of these tolerant strains are described and possible implications with regard to occurrence of tolerance under practical conditions are discussed.

“…Compared with other pathogenic fungi, e.g. Botrytis cinerea (Bollen and Scholten, 1971), Cercospora arachidicola (Littrell, 1974), and Penicillium species (Bollen, 1971), this maximum tolerated dose is rather high, although not exceptionally so. This tolerance was repeatedly found in about 40 isolates over a period of four years.…”

“…These isolates were not cross-resistant to benomyl. In P. brevicompaetum and P. eorymbiferum both benomyl-resistant isolates of each species tested were resistant at the same level (Bollen, 1971). Jarvis and Hargreaves (1973) reported that all isolates of Botrytis cinerea obtained from raspberry and strawberry, where standard benomyl sprays did not control grey mold, grew immediately on 1000 ~g/ml benomyl agar.…”

Effectivertess of benzimidazole fungicides in controlling Vertieillium disease of the commercial mushroom, Agarietts bisporus, was closely correlated with the differential in vitro activity. Thiophanatemethyl was an exception as greater disease control was achieved than expected from its in vitro activity.About one year after clearance for use of benzimidazole fungicides in mushroom growing, resistance in V. fungieola (Preuss) Hassebr. (syn. V. malthousei Ware) appeared on Dutch farms. In vitro, tests were made to determine the degree of resistance of two isolates, R1 and R2, obtained from diseased sporocarps from benomyl-sprayed crops. Mycelial growth of R2 was considerably less inhibited by MBC-fungicides than that of R1. In vivo, R1 was more pathogenic to mushrooms than a freshly made benomyl-sensitive isolate. Both benomyl-resistant isolates were cross-resistant to other MBC-fungicides and to thiabendazole and cypendazole. Likewise, two new experimental fungicides, imazalil and vinchlozolin, did not provide promising alternatives. When appearance of resistance in V. fungicola is suspected on mushroom farms, additional emphasis should be laid on farm hygiene to achieve disease control.

“…She found that amounts of 0.15 to 0.60 kg ha-1 left most rhizosphere and root-colonizing fungi unaffected, but that the Penicillium population was markedly increased in treated plots. The increase in these sensitive fungi might have been due to development of resistance, as has been reported for some species of this genus (Bollen, 1971;Kuramoto, 1976). In contrast to their frequent occurrence on wheat roots in Weber-Czerwifiska's plots, penicillia were rare on roots of rye in our plots.…”

The mycoflora of culm bases and roots of rye was assessed in field trials, where benomyl was applied at dose rates ranging from 0.24 to 4.80 kg ha-2. Samples of culm bases were taken three times during the growing season, those of roots only at the harvest date. On culms with various symptoms from untreated plots, Pseudocercosporella herpotrichoides, AIternaria spp. and Gerlachia nivalis were prevalent and on those from benomyl-treated plots Alternaria spp. and Fusarium culmorum. In later stages of growth, G. nivalis sharply declined and Alternaria spp. and F. culmorum increased. At the end of the season, Periconia macrospinosa and Typhula incarnata appeared in treated plots.In samples of roots taken more than two months after the last spray, porosporous dematiaceous species (Alternaria, Ulocladium and Dendryphion), Mortierella spp. and other resistant fungi were prevalent in plots treated with 1.20 kg ha-a or more, but not in those that received 0.24 kg ha-1, which is recommended for disease control. Lower counts were recorded only for species that are highly sensitive in vitro, e.g. Microdochium bolleyi and Trichoderma spp. Some fusaria were either not affected or tended to be slightly stimulated by the treatment. An attempt was made to attribute the incidence of these moderately sensitive fungi to the effect of the fungicide on non-pathogens.
