ABSTRACT Ulocladium atrum (strain 385) consistently reduced Botrytis cinerea sporulation on necrotic fragments of strawberry leaves. On these tissues, two strains of U. atrum (isolates 18558 and 18559) showed lower antagonistic activities than the reference strain 385. Colonization of strawberry leaflets by the three U. atrum strains appeared similar in the absence of B. cinerea, whether quanti...
The effectiveness of biological control agent, Ulocladium atrum (isolates U13 and U16) in protecting Vitis vinifera L. cv. Chardonnay against gray mold disease caused by Botrytis cinerea, and simulation of the foliar defense responses was investigated. A degraded mycelium structure during cultural assay on potato dextrose agar revealed that U. atrum isolates U13 and U16 were both antagonistic t...
A fractions obtained from the culture fluids of a seven fungal species identified as Verticillium albo-atrum; V. lecanii; V. bulbillosum; V. dahliae; Fusarium solani; F. oxysporum, and Aspergillus sclerociarum were shown to contain a compounds with a biological activity against twenty two clinical bacterial strains including eleven isolates of gram positive and other were gram negative. Among t...
Vascular wilt diseases caused by soil-borne pathogens are among the most devastating plant diseases worldwide. The Verticillium genus includes vascular wilt pathogens with a wide host range. Although V. longisporum infects various hosts belonging to the Cruciferaceae, V. dahliae and V. albo-atrum cause vascular wilt diseases in over 200 dicotyledonous species, including economically important c...
Verticillium wilt is a major threat to alfalfa (Medicago sativa) and many other crops. The model legume Medicago truncatula was used as a host for studying resistance and susceptibility to Verticillium albo-atrum. In addition to presenting well-established genetic resources, this wild plant species enables to investigate biodiversity of the response to the pathogen and putative crosstalk betwee...
A key to the genera of Eumeninae occurring in Oceania is presented. Hitherto there has been no published these genera, making routine identification difficult. New combinations are Pararrhynchium atrum emifasciatum (Giordani Soika), simillimum Parodynerus mariannensis (Bequaert and Yasumatsu), Phimenes solomonis malaitensis (van der Vecht).
