Abstract:

Rhizoctonia solani inoculum can be present either as soil- or tuber-borne sclerotia or hyphae. Although both inoculum sources play a role in disease development, it is not clear which of the two is more important. Successive cultivation of potato crops increases R. solani soil inoculum load resulting in an escalation in disease incidence and severity. The use of tolerant cultivars, however, can effectively reduce inoculum levels thereby decreasing disease intensity. Four pot trials were conducted; the objective of the first two pot trials was to determine the effect of tuber and soil-borne ino

Thesis (MScAgric)--University of Stellenbosch, 2005.<br>ENGLISH ABSTRACT: Grey mould, caused by Botrytis cinerea, is the most important foliar disease of rooibos seedlings. Although the disease is primarily controlled with applications of fungicides, the improvement of cultural methods of disease management should lessen this dependence on chemical control. Such improvements would, however, not be possible without knowledge of the inoculum sources and dispersal of the pathogen. The aim of this study was to investigate the inoculum ecology of B. cinerea in rooibos nurseries in order to ide

Abstract:

Quantification of soilborne pathogen inoculum loads is important in both agricultural and wildland settings. Quantitative Polymerase Chain Reaction (qPCR) methods using SYBR Green chemistry have been shown to be useful for quantifying fungal inoculum loads in environmental samples. The purpose of this study was to develop a method to quantify fungal pathogen inoculum loads in soil seed banks using a qPCR method with SYBR Green chemistry. The invasive annual grass Bromus tectorum was chosen for this seed bank study. There were three objectives: 1) to design target-specific primers for three fun

Abstract:

The use of a biofungicide on the perfect stage of V. inaequalis on leaf litter is one potential way to reduce the number of fungicides used to control apple scab. The previous in vitro screenings of Quebec mycoflora have shown that several isolates are able to significantly reduce the primary inoculum of the pathogen. Among the screened fungi, P176A and P130A, reduced over 98% of the ascospore production and were as effective as Athelia bombacina. However, because in vitro tests are generally poor predictors of in vivo assays a re-evaluation of the antagonists was done under field conditions.

Abstract:

Thermophilic anaerobic digestion offers certain advantages over mesophilic anaerobic digestion such as a higher rate of biogas production and significant pathogen reduction. Despite such advantages, there remain some key hurdles preventing the wider adoption of thermophilic digestion, one of them being that of a difficult start up procedure. To overcome this limitation, this thesis aims to determine suitable start-up conditions and inoculum sources suitable for thermophilic anaerobic digestion. Cow manure, a well-known source of methanogens, was compared to municipal solid waste (MSW) as seeds

Abstract:

This study was aimed to assess the effect of fecal inocula from horses fed on concentrate (restricted amount daily) and oat straw (ad libitum) supplemented with fibrolytic enzymes on in vitro hindgut activity. Cellulase (CE), xylanase (XY) and CE+XY (1:1 v/v; CX) were tested at three levels (μL/g DM): 0, 1 and 3, in addition to control without enzyme addition (EP0). Fecal inocula were collected from 16 Quarter Horse mares supplemented with enzyme at 0 (FCOwithout enzyme), or fed 10 ml enzyme/mare/day of CE (FCE), XY (FXY) or CE+XY (1:1 v/v; FCX) for 15 days.

Abstract:

Gibberella zeae (anamorph: Fusarium graminearum) is the causal agent of fusarium head blight (FHB) and maize ear rot, two major diseases of wheat and corn in Eastern Canada.<br>In Quebec, Microsphaeropsis sp., an antagonist of Venturia inaequalis, the causal agent of apple scab, was isolated from the apple leaf litter. This fungus, well adapted to Quebec climate, can reduce the initial inoculum of V. inaequalis. FHB and Gibberella ear rot are similar to apple scab because the major inoculum source comes from melanized structures produced on crop residues. Consequently, we evaluated the potenti

Abstract:

Septoria blight of celery (Apium graveolens var. dulce), induced by Septoria apiicola Speg., is a destructive disease that requires fungicide applications for its management. A reliable method of inoculum production was established. Best sporulation was obtained on celery agar (CA) at a predicted optimum temperature of 22.4$ sp circ$C. A moderate inoculum density within a range of 17-35 conidia/cm$ sp2$ of leaf surface provided non-coalescing lesions necessary for rapid enumeration. Initial blight incidence thresholds of about 0.6 and 0.5% to time the first fungicide application were establish

Abstract:

Fusarium head blight (FHB) is one of the most economically important diseases of small grains and continues to impact crops when environmental conditions are favorable to Gibberella zeae (Fusarium graminearum), the causal agent of the disease. Corn residues are considered to be primary sources of inoculum for epidemics of FHB. Therefore, knowledge of the movement of Gibberella zeae from a local source of infested corn residue is critical to the management of FHB in wheat and barley. Previous research made significant progress in defining the spatial dissemination of inoculum sources of G. z

Abstract:

Field experiments were conducted at Live Oak, Florida, and Rhodesdale, Maryland, to evaluate the effect of variable seed-borne inoculum load of Dickeya dianthicola on potato plant emergence, plant growth throughout the growing season, disease prevalence in the field throughout the growing season, yield and grade, and transmission of D. dianthicola to progeny tubers. No statistically significant differences in emergence, plant height, or disease incidence were observed at either location. Statistically significant differences were observed in yield at the Florida location; all inoculated treatm

Dans un contexte d'usage raisonné des antibiotiques lié au développement des résistances bactériennes, il est pertinent de chercher à optimiser les profils d'exposition plasmatique qui conduiraient à la meilleure efficacité de l'antibiotique sur les bactéries pathogènes. La charge bactérienne n'est pas stationnaire tout au long du développement d'une infection, mais elle augmente spontanément ou diminue avec un traitement antibactérien efficace. L'objectif de cette thèse était d'évaluer l'influence de la variation de la charge bactérienne sur l'efficacité des antibiotiques et du système immuni
