Growth of alfalfa (Medicago sativa cv. Vernal) seedlings was compared after inoculation with combinations of either Pratylenchus penetrans and Fusarium soloni or P. penetrans and F. oxysporum f. sp. medicaginis. A synergistic disease interaction occurred in alfalfa when F. oxysporum and P. penetrans were added simultaneously to the soil. Alfalfa growth was suppressed at all inoculum levels of P...

Abstract Background Plant disease administration is difficult due to the soil-borne nature of phytopathogens. Biological control plant a safe mode avoid problems related fungal diseases that affect crops productivity. Results Twenty-three Trichoderma isolates were isolated from soil, surrounding healthy tomato roots different regions in Egyptian Governorate Menoufia. Using dual culture method t...

The studies on the biocontrol potential of pink pigmented facultative methylotrophic (PPFM) bacteria other than the genus Methylobacterium are scarce. In the present study, we report three facultative methylotrophic isolates; PPO-1, PPT-1, and PPB-1, respectively, identified as Delftia lacustris, Bacillus subtilis, and Bacillus cereus by 16S rRNA gene sequence analysis. Hemolytic activity was t...

Although the vascular pathogen Fusarium oxysporum is notorious for being causal agent of wilt disease, vast majority F. strains are harmless soil and root colonizers. The latter oxysporum’s often endophytes colonizing roots intracellularly without negatively affecting plant fitness. Actually, most them, like Fo47, beneficial providing biological control to various pathogens. Interestingly, also...

The effectiveness of biochar application to promote plant growth and suppress diseases is usually dependent on the dose biochar. Here, we evaluated effects supplied at 0%, 1%, 2%, 3% (w/w) tomato growth, Fusarium wilt disease severity, rhizosphere microbial community diversity. We found that applied 1% 2% promoted decreased severity disease. High-throughput amplicon sequencing indicated alpha d...

Fusarium oxysporum is the causal agent for wilt diseases of many major ornamental and horticultural crops. In this study, we plated a local cut flower grower’s soil, with a persistent history of Fusarium wilt of scented stock, Matthiola incana but not the lettuce rotational crop. This yielded culture plates with characteristic pink to carmine red fungi, together with a mixed bacterial populatio...

BACKGROUND Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris, a main threat to global chickpea production, is managed mainly by resistant cultivars whose efficiency is curtailed by Fusarium oxysporum f. sp. ciceris races. METHODOLOGY We characterized compatible and incompatible interactions by assessing the spatial-temporal pattern of infection and colonization of chickpea cvs. P-2245...

Trichoderma fungi are promising candidates for biocontrol agents and plant growth promoters. atrobrunneum T. simmonsii were evaluated the control of soil-borne phytopathogenic fungi, in present study. Dual culture tests with Rhizoctonia solani Fusarium oxysporum f. sp. lycopersici used to conduct vitro evaluation. In presence Trichoderma, phytopathogen’s rate was inhibited up 59.70% R. 42.57% F...

Tomato Fusarium wilt caused by oxysporum f.sp. lycopersici (Fol) constrains tomato production worldwide. Three hundred forty accessions were evaluated for resistance and single nucleotide polymorphisms (SNPs) associated with resistance. The disease evaluation revealed that 15, 13, 15 identified as resistant in Test 1, 2, Mean data, respectively, the severity index (DSI) ranging from 0-16.7%. A ...
