| dc.description | Endophytes from wheat cultivars isolated in Buenos Aires province, Argentina, were assessed for their potential as biocontrol agents against<em>Pyrenophora tritici-repentis</em>(Died.) Drechsler (anamorph<em>Drechslera tritici-repentis</em>) (Died.) Shoem (<em>Dtr</em>), the causal agent of tan spot of wheat. Endophytes were screened using dual culture techniques and examining the effect on growth, sporulation and the antifungal activity in greenhouse assays. The most of endophytes tested significantly reduced<em>Dtr</em>growth compared to the control except<em>Rhodotorula rubra</em>from 11 to 15days post inoculation.<em>Trichoderma hamatum</em>,<em>Penicillium</em>sp.,<em>Bacillus</em>sp. and<em>Paecilomyces lilacinus</em>significantly reduced the colony diameter of the pathogen. Most of the endophytes evaluated showed morphological changes in the conidia and/or the mycelia of<em>D. tritici-repentis</em>. In addition, two endophytes,<em>Bacillus</em>sp. and<em>Fusarium</em>sp., reduced significantly the percent spore germination of<em>Dtr</em>compared to the control by 82% and 52% respectively. In greenhouse experiment<em>T. hamatum</em>,<em>Chaetomium globosum</em>and<em>Fusarium</em>sp. significantly (<em>P</em>⩽0.05) reduced the average disease severity on all three leaves compared to the control. However, the best antagonistic effect was shown with<em>T. hamatum</em>as it resulted in the greatest suppression in the greenhouse and in the dual-plate assays. Likewise,<em>Bacillus</em>sp. was other highlighted microorganism that antagonized the pathogen in<em>in vitro</em>assays. From our promising results, we conclude that endophytes have potential in the biological control of tan spot of wheat caused by<em>D. tritici-repentis</em>, particularly<em>T. hamatum</em>and<em>Bacillus</em>sp. | - |
