lentil wilt, caused by fusarium oxysporum f. sp. lentis is one of the main limiting factors to successful lentil cultivation. effect of four antagonistic fungi, namely: piriformospora indica, sebacina vermifera, trichoderma viride and trichoderma harzianum as well as combinations among them were evaluated against fusarium wilt of lentil. in in vitro experiments, the effect of the antagonistic f...

Microbes have evolved ways of interference competition to gain advantage over their ecological competitors. The use of secreted antagonistic compounds by yeast cells is one of the prominent examples. Although this killer behavior has been thoroughly studied in laboratory yeast strains, our knowledge of the antagonistic specificity of killer effects in nature remains limited. In this study, yeas...

background and objectives: to find antagonistic bacteria with potential antifungal activity against some pathogenic fungi, including aspergillus niger , a. flavus, fusarium moniliforme and penicillium marneffei , a total of 148 agricultural soil samples from different sites of tehran were examined.  materials and methods: antagonistic soils were selected by screening against a. niger on glucose...

We studied the possibility that the antagonistic saprobe fungi Coriolopsis rigida, Trametes versicolor, Fusarium lateritium, Penicillium chrysogenum and Verticillium dahliae-2379 may control V. dahliae disease through the inhibition of the activity of hydrolytic enzymes produced by the pathogen. These saprobe fungi were able to decrease the growth in vitro of V. dahliae. The exudates produced b...

Four Lentinula edodes strains (Le10, 46, K2, Assai) were assessed for their antagonistic effect on four filamentous fungus species of agricultural importance (Helminthosporium euphorbiae, Helminthosporium sp, Fusarium solani and Phomopsis sojae) and on Alagoas serotype of Vesicular Stomatitis Virus (VSA). The L. edodes strains studied had variable effects on the filamentous fungi and on VSA. Th...

considering the deleterious effects of chemical pesticides used in agriculture including cotton cultivation, the search about integrated control strategies for important cotton diseases, verticillium wilt and rhizoctonia seedling damping-off is clearly obvious. in this present study, the researcher investigated the effectiveness of the integration of two strategies, biological control (using an...
