Studies on red crown rot of soybean: incidence in Illinois, fungicide seed treatments, and host resistance
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-14 without embargo terms

Evaluation of Host Resistance and the Utilization of Organic Amendments to Manage Macrophomina Crown Rot of Strawberry in California
… production inciting the disease Macrophomina crown rot. When established, the pathogen can cause extensive plant decline and mortality. Host resistance will be a critical tool for managing this disease and guiding breeding programs in the post methyl bromide era. Evaluation of host resistance …

Evaluating populations derived from complex crosses involving both bread wheat and durum wheat parentage for partial resistance to crown rot
Crown rot in durum, caused by Fusarium pseudograminearum and Fusarium culmorum, can reduce yields up to 90% in seasons characterised by limited spring rainfall. To decrease this potential loss, breeding of partially resistant cultivars could complement agronomic approaches. However, the limited …

Quantitative analysis of active compounds found in Arnica montana and Arnica chamissonis in relation to varied provenance, environmental and agronomic factors.
… had high quality extract but was prone to crown rot and was less robust than initial trials suggested. Conversely, while A. chamissonis grew vigorously, the extract contained approximately a third of the sesquiterpene lactone content.

IDENTIFICATIN AND CHARACTERIZATION OF PATHOGENICITY GENES IN FUSARIUM VIRGULIFORME, THE CAUSAL AGENET OF SUDDEN DEATH SYNDROME (SDS) IN SOYBEAN
… States. Fungal infection results in root and crown rot as well as SDS typical foliar symptoms including chlorosis, necrosis and complete defoliation. The use of soybean cultivars tolerant to SDS is still the most effective way to overcome the disease. On the other hand, the fungal isolates are …

Root Rot Pathogens of Wheat in South Dakota and Their Affect on Seed Germination and Seedling Blight in Spring Wheat Cultivars
<p>Crown rot and common root rot are the important root diseases in wheat (<em>Triticum aestivum</em> L.) and other cereals causing significant germination and yield losses in the Northern Great Plains and other parts of the world. <em>Bipolaris sorokiniana</em> (Bs) and <em>Fusarium …

FUSARIUM MUSAE AND FUSARIUM VERTICILLIOIDES CROSS-KINGDOM PATHOGENS: GENOMICS AND DIAGNOSTIC INNOVATION
… acting as the causal agent of postharvest banana crown rot while increasingly being reported in human infections. Despite its growing relevance, the biology, genomic diversity, and mechanisms underlying host adaptation in F. musae remain insufficiently characterized, and available genomic …

Fusarium in winter wheat: mycotoxin accumulation in straw and a survey of roots
… for many diseases including Fusarium root rot (FRR), Fusarium crown rot (FCR), and Fusarium head blight (FHB). In recent years, Fusarium mycotoxins, primarily deoxynivalenol (DON), 3-acetyldeoxynivalenol (3ADON), and 15-acetyldeoxynivaleol (15ADON), have been detected in conjunction with …

FUSARIUM MUSAE, A NEW POTENTIAL TRANSKINGDOM PATHOGEN.
… identified is F. musae, a causative agent of crown rot disease in bananas that has also been implicated in superficial infections in immunocompromised human patients. This thesis aims to investigate F. musae as a model organism for studying transkingdom pathogens, integrating methodologies …

Investigating Novel Approaches for the Integrated Control of the Soilborne Strawberry Pathogens Macrophomina phaseolina and Fusarium oxysporum f. sp. fragariae
… are emerging soilborne pathogens causing crown rot and Fusarium wilt, respectively, in commercial strawberry production in California. Fungicides representing eight active ingredients from four different mode of action groups (FRAC groups 1, 3, 7 and 12) were evaluated for their efficacy …

FUNCTIONAL DIVERSITY OF FUNGI ASSOCIATED WITH DURUM WHEAT ROOTS IN DIFFERENT CROPPING SYSTEMS
… in cereals is based on the examination of the subcrown internode. I evaluated the method by comparing the fungal communities associated with different subterranean organs of durum wheat. The fungal community of the subcrown internode was different from that of roots and crown, suggesting cautious …
