This book was released on 2022-01-07 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gray mold or Botryotinia fuckeliana (de Bary) Whetzel (syn. Sclero-tinia fuckeliana (de Bary) Fuckel) (anamorph B. cinerea Pers.), ac-cording to taxonomic characteristics, belongs to the genus Botry-otinia (family Sclerotiniaceae) is a plant disease that is widespread wherever the vine is grown as an agricultural crop. This cosmopolitan fungus is a pathogen attacking over 200 plant species, including the grapevine (Jarvis, 1980). Members of Botrytis genus are generally necrotrophic pathogens they induce host cell death and lysis to access cellular nutrients.

Download or read book Ecology and Population Biology of Botrytis Cinerea on Red Raspberry and Other Small Fruit Hosts in the Pacific Northwest written by Olga Kozhar and published by . This book was released on 2019 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Botrytis cinerea is the causal agent of gray mold of more than 1,400 plant host species. The disease can lead to substantial yield losses, especially of red raspberry and other small fruit crops in the US Pacific Northwest (PNW) and worldwide. Effectiveness of gray mold management in red raspberry remains limited due to incomplete understanding of the disease cycle. The bloom period of red raspberry is considered a critical window for B. cinerea colonization of this host, but the role of flowers in this disease remains unclear. The first objective of this research was to determine the infection pathways of B. cinerea on red raspberry under field conditions. Colonization incidence of red raspberry at bloom was limited, but significantly increased with fruit development and peaked on mature fruit. As fruit developed, different morphological parts became colonized by the fungus, suggesting multiple infection events throughout the season.In the PNW, gray mold management programs on raspberry are based on protecting plants with fungicides throughout the production season, starting at bloom. It is, however, unknown if full-season fungicide programs are required to control B. cinerea effectively on raspberry. The second objective of this research was to study the effect of fungicide applications on B. cinerea colonization of raspberry in relation to plant development and test the floral infection hypothesis with genetic markers. Fungicide applications did not prevent or reduce flower colonization but significantly decreased fruit colonization. Pathogen genotypic diversity increased throughout the season and different genotypes colonized flowers, green and ripe fruit within raspberry inflorescence, suggesting that multiple fungal strains can colonize fruit at different developmental stages.In the PNW, several small fruit hosts are grown in close proximity, but nothing is known about B. cinerea population biology on these hosts in this region. The third objective of this research was to investigate how evolutionary forces shape pathogen population structure on small fruit in the PNW. No association of B. cinerea with host was found, but populations were geographically differentiated at regional and farm scales, suggesting restricted gene flow. Evidence for local adaptation due to selection was detected with fungicide resistance markers.

Download or read book Role of Inoculum Sources of Botrytis Cinerea in the Epidemiology of Gray Mold of Snap Beans written by Kenneth Bjorn Johnson and published by . This book was released on 1982 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spore dispersal gradients and pod disease gradients from point inoculum sources of Botrytis cinerea were measured over time in two snap bean field experiments. Laboratory grown inoculum was placed at ground level in a 30 x 30 cm square at bloom initiation and removed at full bloom. Dispersal of inoculum, assessed by quantifying spores washed from bean foliage, was limited to within 3 m from the inoculum source during bloom. At harvest, the spore populations on plants were 20 to 30 times higher than populations at full bloom due to secondary production of inoculum. At two sampling times during bloom, incidence of B. cinerea on senescing blossoms averaged 70 percent at a distance of 0.9 m from the inoculum source but less than 25 percent at distances greater than 4 m. In one experiment, the incidence of pod rot at harvest averaged 7.2 percent at 0.9 m from the inoculum source but only 1.3 percent at a distance of 4.5 m. Spore dispersal gradients analyzed by regression of the form log Y = a + b log X showed significant flattening at harvest compared to full bloom, whereas gradients for pod rot incidence at harvest did not flatten when compared to incidence of B. cinerea on blossoms at full bloom. Blossom infections early in the bloom period from point inoculum sources were important in pod rot development. To determine if within-field inoculum sources are important in pod rot development in commercial snap bean production, an observational study was conducted in five bean fields in Oregon's Willamette Valley. Senescing cotyledons were the initial plant tissue colonized by Botrytis cinerea. Young stem tissues and leaf tissues also became diseased and served as within-field inoculum sources. The number of these inoculum sources before bloom varied between fields and ranged from 14.8 to 0.2 per 5 m row. The number of spores per plant at bloom initiation and the incidence of B. cinerea on blossoms at full bloom was positively correlated with the number of prebloom inoculum sources within a field. Using the number of inoculum sources prior to bloom as a predictive variable, 50 percent of the variation in the incidence of pod rot among fields could be explained. A multiple regression model, which included the number of inoculum sources before bloom, frequency of irrigation, duration of leaf wetness due to irrigation and rain, and canopy size explained 82 percent of the variation in percent pod rot among fields.

Download or read book Sustainable Agriculture Reviews 51 written by Praveen Guleria and published by Springer Nature. This book was released on 2021-04-12 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of climate change, pollution and food safety, the current challenge is to enhance legumes production to sustain the growing population needs by 2050. This is a daunting task because abiotic and biotic stresses are threatening the growth, survival and productivity of legumes. For instance, the productivity of legumes is documented to be reduced by 14-88% by abiotic stresses. The co-occurrence of abiotic and biotic stresses under field conditions leads to interactive stress types, thus yielding positive or negative outcomes. Legumes react using antioxidant defense, osmoregulatory adjustments, hormonal regulations and molecular mechanisms to tolerate stress. Hence, improving legume productivity requires knowledge on the sensitivity, mechanisms and approaches of stress tolerance in legumes, in order to design new crops and alternative management systems. This book presents advances on bioactive compounds, applications, effect of various stresses and biotechnology-based stress tolerance mechanisms of legumes. This is our second volume on Legume Agriculture and Biotechnology, published in the series Sustainable Agriculture Reviews.

Download or read book Biology of Microfungi written by De-Wei Li and published by Springer. This book was released on 2016-03-18 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book includes 24 chapters written by a group of experts in the different fields of microfungi and cover a broad range of topics on microfungi. It provides the most updated information on the latest development in systematics and taxonomy of microfungi, new techniques which were developed in the last ten years and their application in microfungal research. After the International Code of Nomenclature for algae, fungi, and plants (Melbourne Code) was adopted by the Eighteenth International Botanical Congress Melbourne, Australia, July 2011, it has had a profound impact on mycology and its research. Fungal nomenclature changes and its significance to fungal taxonomy and naming of microfungi in the future is discussed in detail. Since dual names system for fungi developing both sexual and asexual states, and fungi developing only asexual state is no longer available, the first five chapters will clarify some confusion and provides perspective views on the direction for future research. The next nine chapters cover microfungi and their ecological roles or functions in the different habitats (air, indoor, aquatic, marine, plants, soils, etc). The remaining 13 chapters cover the relationship of microfungi and humans (good and bad) and usage or application microfungi in different industries, such as food, agriculture, forestry, green technology, pharmaceutics, and medicine, as well as in our daily life. The book bridges the gap between basic mycological research and applied mycology and provide readers a unique set of information and knowledge of microfungi generated from multiple angles in different fields of mycology.

This book was released on 2013-06-28 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological disease management tactics have emerged as potential alternative to chemical application for containing crop diseases. Biotic and abiotic biological control agents (BCAs) have been demonstrated to be effective against diseases caused by microbial plant pathogens. Combination of biotic and abiotic agents leads to synergism and consequent improvement in the effectiveness of disease control. It is essential to assay the biocontrol potential of all isolates/species of fungal, bacterial and viral biocontrol agents by different techniques in vitro and under greenhouse and field conditions and to precisely identify and differentiate the most effective isolates from less effective ones by employing biological, immunological and nucleic acid-based assays.
