Interesting dematiaceous Hyphomycetes on Lodoiceamaldivica dead fragments
No full textTwo new species, Virgariella lodoicea and Cacumisporium oceanicum and a new record of Diplocladiella scalaroides from Seychelles islands are proposed. A species of Helicosporium which could not be determined is also described

Dematiaceous Hyphomycetes from Bosco Isola (S Italy) Mediterranean maquis litter
Full text linkThis is the fifth contribution to the knowledge of Dematiaceous Hyphomycetes colonizing the litter in Mediterranean maquis. Twelve species are described and notes on the morphological characters are pointed out. Three of them are reported as genus, they need an examination of more materia
Effects of soil applications of Benomyl and Captan on the growth of onions and the occurrence of endophytic mycorrhizas and rhizosphere microbes.
No full textWhen grown for 6 months in the absence of pathogens, repeated soil applications of benomyl or captan significantly and similarly decreased growth of onion seedlings by 22–25% (diameter) and 31–34% (dry weight). The losses were associated with differing effects on soil microbes. Whereas captan had no effect on the occurrence of vesicular-arbuscular mycorrhizas it appreciably decreased populations of rhizosphere fungi. In contrast benomyl inhibited mycorrhiza formation but had a relatively small effect on rhizosphere fungi
Effects of Benomyl anf Captan on rhizosphere fungi and the growth of Allium cepa.
No full textThe effects of soil treatment with Benomyl or Captan on the rhizosphere fungi of Allium cepa were investigated. The mycoflora of the rhizosphere was considerably inhibited by both fungicides. Captan was more inhibiting than Benomyl, but the latter seemed to be more persistent. The fungi isolated from the rhizosphere of control plants, plants treated with Benomyl or with Captan are listed and differences between treatments are discussed. The total number of species isolated from the rhizosphere of control plants was 65, Benomyl 44 and Captan 29. The growth of onions receiving fungicide treatment was greatly reduced: differences in dry weight were 31% (Captan) and 36% (Benomyl) less than control plants
