incorporation of brassica seed meal Soil amendment and wheat cultivation for control of macrophomina phaseolina in strawberry
European Journal of Plant Pathology, 2017Co-Authors: Mark Mazzola, Aaron Agostini, Michael CohenAbstract:Macrophomina. phaseolina is the cause of charcoal rot, a disease of emerging importance in strawberry production systems. Brassicaceae seed meals (SM) and prior cultivation of Soils with wheat were evaluated for the capacity to suppress charcoal rot of strawberry and to determine the relative contribution of seed meal derived chemistry and Soil Biology in disease control. Brassicaceae seed meal amendments suppressed the abundance of M. phaseolina detected in Soil systems, but optimal SM-induced pathogen suppression required a functional Soil Biology. Suppression of M. phaseolina was obtained with SM sourced from various Brassicaceae species and was not associated with a biologically active chemistry such as that generated by Brassica juncea SM amendment (e.g. allyl isothiocyanate). Disease control observed in natural Soil was abolished when SM amended Soils were pasteurized prior to infestation with M. phaseolina, suggesting a functional role of Soil Biology in disease suppression that was observed. Cultivation of Soils with wheat prior to pathogen infestation resulted in a level of disease control superior to SM amendment, however no additive effect on disease suppression was observed with integration of the two treatments. In small scale field trials, SM amendment induced phytotoxicity was observed and may have contributed to a lack of apparent control of charcoal rot. In the same trials, significant weed control was achieved in response to SM amendment. Across trials conducted in controlled and field environments there has been a lack of consistent association between the effect of SM amendment or wheat cultivation on M. phaseolina Soil density and resulting level of root infection. This suggests that the observed disease control may have a greater dependence upon microbial interactions that transpire in the rhizosphere than that which occurs in the bulk Soil environment.

Apple Replant Disease: Role of Microbial Ecology in Cause and Control
Annual Review of Phytopathology, 2012Co-Authors: Mark Mazzola, Luisa M. ManiciAbstract:Replant disease of apple is common to all major apple growing regions of the world. Difficulties in defining disease etiology, which can be exacerbated by abiotic factors, have limited progress toward developing alternatives to Soil fumigation for disease control. However, the preponderance of data derived from studies of orchard Soil Biology employing multidisciplinary approaches has defined a complex of pathogens/parasites as causal agents of the disease. Approaches to manipulate microbial resources endemic to the orchard Soil system have been proposed to induce a state of general Soil suppressiveness to replant disease. Such a long-term strategy may benefit the existing orchard through extending the period of economic viability and reduce overall disease pressure to which young trees are exposed during establishment of successive plantings on the site. Alternatively, more near-term methods have been devised to achieve specific quantitative and qualitative changes in Soil Biology during the period of or...

role of native Soil Biology in brassicaceous seed meal induced weed suppression
Soil Biology & Biochemistry, 2008Co-Authors: Lori Hoagland, John P. Reganold, Lynne Carpenterboggs, Mark MazzolaAbstract:Abstract Biologically based weed control strategies are needed in organic and low-input systems. One promising practice is the application of Brassicaceous seed meal (BSM) residue, a byproduct of biodiesel production. When applied as a Soil amendment, BSM residue has exhibited potential bioherbicide activity. In this study, tree fruit orchard Soils were treated with various BSMs and the impact of Pythium on weed suppression was examined in field and greenhouse studies. Although weed control obtained in response to Brassicaceous residue amendments has been repeatedly attributed solely to release of allelopathic phytochemicals, multiple lines of evidence acquired in these studies indicate the involvement of a microbiological component. Reduced weed emergence and increased weed seedling mortality were not related to BSM glucosinolate content but were correlated with significant increases in resident populations of Pythium spp. in three different orchard Soils. Seed meal of Brassica juncea did not amplify resident Pythium populations and did not suppress weed emergence. Application of Glycine max SM did stimulate Pythium spp. populations and likewise suppressed weed emergence. Application of a mefenoxam drench to Pythium -enriched Soil significantly reduced weed suppression. These studies indicate that a microbial mechanism is involved in SM-induced weed suppression and that selective enhancement of resident pathogenic Pythium spp. can be utilized for the purpose of weed control.

Soil Health, Soil Biology, Soilborne Diseases and Sustainable Agriculture: A Guide
2016Co-Authors: Graham Stirling, Helen L. Hayden, Tony Pattison, Marcelle StirlingAbstract:Our capacity to maintain world food production depends heavily on the thin layer of Soil covering the Earth's surface. The health of this Soil determines whether crops can grow successfully, whether a farm business is profitable and whether an enterprise is sustainable in the long term. Farmers are generally aware of the physical and chemical factors that limit the productivity of their Soils but often do not recognise that Soil microbes and the Soil fauna play a major role in achieving healthy Soils and healthy crops. Soil Health, Soil Biology, Soilborne Diseases and Sustainable Agriculture provides readily understandable information about the bacteria, fungi, nematodes and other Soil organisms that not only harm food crops but also help them take up water and nutrients and protect them from root diseases. Complete with illustrations and practical case studies, it provides growers and their consultants with holistic solutions for building an active and diverse Soil biological community capable of improving Soil structure, enhancing plant nutrient uptake and suppressing root pests and pathogens. The book is written by scientists with many years' experience developing sustainable crop production practices in the grains, vegetable, sugarcane, grazing and horticultural industries. This book will be useful for: growers, consultants, agronomists and Soil chemists, extension personnel working in the grains, livestock, sugarcane and horticultural industries, professionals running courses in Soil health/biological farming, and students taking university courses in Soil science, ecology, microBiology, plant pathology and other biological sciences.

highlights and perspectives of Soil Biology and ecology research in china
Soil Biology & Biochemistry, 2009Co-Authors: Shenglei Fu, David C. ColemanAbstract:As seen for the publications in several distinguished Soil related journals, Soil Biology and ecology is booming in China in recent years. This review highlights the major findings of the Soil Biology and ecology projects conducted in China during the past two decades. Special attention is paid on the responses of Soil biota to environmental change, and the roles of Soil functional groups in C transformation, nutrient cycling and pollution remediation. We also point out the future challenges facing the Chinese Soil biologists and Soil ecologists. In the future, more systematic studies rather than scattered case studies are needed, more controlled field experiments rather than short-term laboratory studies should be encouraged. Besides, we need to focus more on the linkage between aboveground and belowground organisms, the interactions between different groups of Soil food web, and the coupling of observation with modeling. It is essential to employ the state-of-the-art technology in research of Soil Biology and ecology because to answer the emerging scientific questions relies heavily on the development of new technology. Our ultimate goals are to push forward the research on Soil Biology and ecology in China and to encourage the interaction and collaboration between the international community and research groups in China.

Soil Biology, Soil ecology, and global change
Biology and Fertility of Soils, 1992Co-Authors: David C. Coleman, Eugene P. Odum, D A CrossleyAbstract:This overview paper addresses aspects of scaling in space and time, and scaling in relation to micro-and macrohabitats. Ecological processes in Soils are examined for possible generalizations about processes and organisms, across a wide range of different habitats. Problems of scaling in space and time that have an important impact on processes associated with global change are outlined.
