Cytospora eucalypticola has been frequently associated with twig and stem cankers and as endophyte of Eucalyptus globulus and E. grandis in Uruguay. Mycelium discs of two C. eucalypticola isolates obtained from actively growing colonies were inoculated, both superficially and on experimentally wounded stems of E. globulus and E. grandis. No inoculated and control plants have shown any discolora...

Sixteen novel pyrazole acyl thiourea derivatives 6 were synthesized from monomethylhydrazine (phenylhydrazine) and ethyl acetoacetate. The key 5-chloro-3-methyl-1-substituted-1H-pyrazole-4-carbonyl chloride intermediates 4 were first generated in four steps through cyclization, formylation, oxidation and acylation. Thess were then reacted with ammonium thiocyanate in the presence of PEG-400 to ...

The producing organism, strain FH-A 6607, was isolated from a soil sample collected near Rantepao, Sulawesi Island (Indonesia) and exhibited a characteristic brown to yellow colored mycelium. The typical conidiophores were found to be in close morphological analogy to gliocladium and are arranged in self-contained long rows (Fig. 1). Combined with further taxonomical investigations the strain F...

The main goal of this work was to detect whether Cytospora chrysosperma and Fusicoccum eucalypti are present as endophytes of symptomless hypocotyls, cotyledons, flowers, capsules, peduncles of flowers in order to interpret an earlier finding of their presence in seeds, seedling stems and twigs of E. globulus. Segments from these organs as well as from bark and the xylem from flower peduncles w...
