Book excerpt: "Venturia inaequalis, the causal agent of apple scab, overwinters in apple leaves on the orchard floor. To develop a control strategy based on the prevention of the maturation of overwintering pseudothecia, a sampling of fungi colonizing dead apple leaves was conducted from different orchard floors in Quebec during the spring and fall of 1993. A total of 345 different isolates were obtained, from which fifteen genera have never been previously recorded as colonizers of apple leaves in North America. Small differences were detected in genera richness among orchards but the fungal composition of each orchard was fairly unique. Different tests on growth on amended media and leaf decomposition demonstrated that leaf degradation is not a reliable parameter alone to screen antagonist against V. inaequalis. No significant relation between growth on amended media, leaf rheology and ascospore inhibition was detected. However, 40 fungi reduced significantly ascospore production more than 87% compared to the control (V. inaequalis only). Of these antagonists, 30% decomposed apple leaves, suggesting that competition for the substrate is involved in the mode of action of at least one third of the antagonits detected. Other possible modes of antagonism are discussed." --

Book excerpt: Using stunning computer animation blended with real-life in-field footage, this educational video impressively illustrates the life cycle of the apple scab fungus Venturia inaequalis. Students and extension audiences will gain a clear understanding of the development and epidemiological spread of this disease and how it can be controlled using integrated pest management (IPM) practices. Apple Scab Venturia inaequalis is an authoritative presentation of a disease that is found in most of the world's apple-growing regions.This video is dedicated to Professor Dr. Dr. h.c. Günter Martin Hoffmann (1923-2013), one of the fathers of Integrated Pest Management. He was a full professor of plant pathology at the Technical University of Munich-Weihenstephan, Germany. His research and teaching focused on the epidemiology of fungal pathogens of major crops and their integrated control by developing several IPM prognosis models. Professor Hoffmann was an enthusiastic apple grower.PowerPoint Lets You Add Specific Video Segments to Your Lectures and Talks from the Video Using: Video TrimFull length videos can be trimmed for use in PowerPoint presentations.

Download or read book Biological Control written by Heikki M. T. Hokkanen and published by Cambridge University Press. This book was released on 2003-10-30 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control of insect pests, plant pathogens, and weeds is the only major alternative to the use of chemical pesticides in agriculture and forestry. This book is the first comprehensive attempt at a balanced benefit/risk assessment of biological control. It covers classical biological control of pests and weeds, augmentation of natural enemies, and the use of biopesticides. Unique sections deal with genetic engineering of biocontrol agents and crop plants, economic analysis of biocontrol, and the ecological consequences of the introduction of organisms. The book will be of interest to researchers and postgraduate students in biotechnology, agriculture, forestry, and environmental sciences.

This book was released on 2016 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apple scab, caused by the fungal pathogen Venturia inaequalis is among the most prevalent and economically important diseases in commercial apple orchards in regions with temperate climates worldwide. The absence of durable apple scab resistance in the majority of commercially desired cultivars often mandates numerous fungicide applications each season to successfully manage the disease. Highly effective single-site fungicides have enhanced the ability to manage a number of phytopathogenic fungi, including V. inaequalis. Unfortunately the highly specific nature and repetitive use of these fungicides has led to their diminished efficacy and widespread resistance in V. inaequalis. The identification of the prevalence of single-site resistance in populations of V. inaequalis and an understanding of molecular mechanisms of resistance to these fungicides can aid in the rapid detection of fungicide resistance, the deployment of fungicide anti-resistance management strategies, and the development of efficient and effective chemical management programs for apple scab control. In this dissertation, a combination of applied and basic research was implemented to gain further understanding of the molecular mechanisms associated with practical resistance to DMI and QoI fungicides in isolates and/or populations of V. inaequalis. Microscopy-aided mycelial growth assays were used to determine sensitivity phenotypes to the DMI fungicides myclobutanil and difenoconazole and to the QoI fungicide trifloxystrobin. The majority of populations of V. inaequalis collected throughout the Northeastern, Mid-Atlantic, and Mid-Western United States were found to have reduced sensitivity or practical resistance to myclobutanil, but not difenoconazole. Illumina sequencing and reverse-transcriptase quantitative PCR were used to identify the contribution of target gene overexpression and the presence of upstream repeated elements in myclobutanil and difenoconazole resistance. Another molecular technique, allelespecific quantitative PCR was used to evaluate the role of target gene heteroplasmy in the quantitative resistance response and practical resistance to trifloxystrobin in isolates and populations of V. inaequalis. Additionally, baseline sensitivity of V. inaequalis to three SDHI fungicides was determined, and the sdhB gene, a target for SDHI fungicides, was identified and characterized. In summary, the results of this dissertation contribute to the identification and understanding of mechanisms associated with single-site fungicide resistance in V. inaequalis.

This book was released on 1994 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1992, a research program was initiated to select suitable antagonists against the saprophytic (or winter) phase of the apple scab pathogen, Venturia inaequalis. An improved method for the mass screening of a vast collection of fungi was developed for this purpose. Some of the previously reported criteria such as leaf rheology and overwintering structure production proved unreliable or fastidious and cannot be used for in vitro antagonist selection. The main antagonism selection criterium retained was the in vitro inhibition of ascospore formation. To measure ascospore production, a simplified method of in vitro pseudothecia production was devised. This new method eliminates the need for prior conidia production by using a mycelial suspension and greatly reduces the risks of sterile mating by using a cocktail of Venturia inaequalis strains of different origins. Finally, the production cycle duration was reduced by varying the incubation temperature during the simulated winter. Moreover, a quick and efficient method of ascospore collection was developed. Ascospores were forcibly ejected in a large scale bubbler type apparatus in only one hour. This bubbler can be used for other studies including axenically produced ascospores. This new method compared favourably to the previously reported method and was used to screen a collection of about forty-two fungi. Six proved to significantly reduce the ascospore production of Venturia inaequalis. Two were as effective as Athelia bombacina, a previously reported antagonist of pseudothecia formation and inhibited over 98% of the ascospore production. These new organisms are now available for future field tests. Future selections from a large collection of saprophytes can now be based on a reliable and simple in vitro screening methodology." --
