Available in PDF, EPUB and Kindle. Book excerpt: Rhizosphere biology is approaching a century of investigations wherein growth-promoting rhizomicroorganisms (PGPR) have attracted special attention for their ability to enhance productivity, profitability and sustainability at a time when food security and rural livelihood are a key priority. Bio-inputs - either directly in the form of microbes or their by-products - are gaining tremendous momentum and harnessing the potential of agriculturally important microorganisms could help in providing low-cost and environmentally safe technologies to farmers. One approach to such biologically-based strategies is the use of naturally occurring products such as PGPR. Written by an international team of experts, this book considers new concepts and global issues in biopesticide research and evaluates the implications for sustainable productivity. It is an invaluable resource for researchers in applied agricultural biotechnology, microbiology and soil science, and also for industry personnel in these areas.

Download or read book Influence of Soils Nutrition and Water Relations Upon Charcoal Rot Disease Processes in Kansas written by David Ricardo Jimenez Cruz and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Charcoal rot, caused by Macrophomina phaseolina, is the most important soybean disease in Kansas. Several strategies have been recommended to control this disease including crop rotation, lower plant densities, biological control, plant resistance and tolerance, and fungicide application. However, those techniques have not been completely effective and the information concerning soil texture, irrigation and micronutrient fertility (particularly manganese) upon charcoal rot disease severity and the pathogen population is limited. The objective of this study was to determine key factors that affect the biology of M. phaseolina and charcoal rot processes under laboratory, greenhouse and field conditions. M. phaseolina microsclerotia were produced from PDA pure isolate and infested Japanese millet in the laboratory and characterized by different techniques such as serial dilutions in semi selective media with the aim to produce quality inoculum to reliably infect soybean seedling roots under greenhouse conditions; production of inoculum by infesting Japanese millet was the most efficient method. Root colonization and root infection of soybean seedlings was assessed through the use of M. phaseolina inoculum under controlled conditions in the greenhouse. Root infection by M. phaseolina and microsclerotia longevity in soil is determined by environmental factors such as soil moisture content, soil texture and source of inoculum. The objective of the greenhouse study was to determine the impact of these variables on seedling root infection at the V1 and V2 development stages. Artificial soils with different textures were infested; M. phaseolina microsclerotia and soybean seedlings were exposed to different soil moisture contents including pot saturation, pot (field) capacity, and permanent wilting point. Soil populations and levels of root colonization for the stages were assessed by estimating CFUs and root length. Results indicate that soil texture has a significant impact upon root morphology and root length. Root populations of M. phaseolina were significantly higher in sandy soil textures and lower in the fine-textured soils, suggesting an impact of soil water holding capacity in the root infection process. The effect of water stress on seedling root colonization by M. phaseolina indicates that early infection may be more important than previously thought. A field study was also conducted to determine the effect of the aforementioned variables in a 2-year field experiment conducted at two Kansas locations. Pathogen colonization was iii assessed by measuring colony-forming units (CFUs) from ground root tissue at R2-R4 (post-flowering/early pod development) and R8 (maturity) stages. Soil populations (pre-planting and post-harvest) of M. phaseolina, yield parameters, and plant characteristics were obtained. Results indicated that there are complex relationships between soil physiochemical properties (pH, NPK content, exchangeable cations, and organic matter) and soil texture (sand, soil, and clay composition), which may mitigate disease severity and pathogen levels in host tissue. Results also indicated that in natural M. phaseolina-infested soils, cropping history and soil texture play an important role in charcoal rot processes and influence the levels of pathogen soil populations, root colonization at maturity and, more importantly, soybean yield.

Download or read book Effects of Environment and Genotype on Charcoal Rot Development on Soybeans written by Micah Diane Doubledee and published by . This book was released on 2012 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charcoal rot of soybean, caused by the soilborne fungus Macrophomina phaseolina (Tassi) Goid, is a disease associated with high soil temperature and low soil moisture. Above-ground symptoms, which can be difficult to distinguish from drought symptoms, include low vigor, dead leaves that remain attached to the plant, early senescence and yield loss. Irrigation limits damage, but does not prevent colonization of the tissue by the pathogen. No soybean line is immune to M. phaseolina, but a few lines may have moderate resistance. The objectives of this research were to 1) determine the effects of genotype and drought on the development of charcoal rot and 2) determine the efficacy of non-destructive techniques to measure disease development during the season. In 2008 and 2009, soybean genotypes, DT97-4290 and Delta Pineland 4546 (moderately resistant), LS980358 (susceptible), and R01-581F (drought tolerant) were grown in microplots. Treatments included presence or absence of M. phaseolina and water-stressed and non-stressed in a factorial randomized complete block design experiment with five replications. Soil moisture and temperature, and rainfall were monitored. Root colonization and plant growth were assessed at growth stages V2/V3 and V4/V5. Stomatal conductance was measured with a porometer. Canopy temperature was measured with an infrared thermometer and used to calculate Crop Water Stress Index (CWSI). Canopy reflectance was measured with a spectroradiometer and used to calculate ten vegetative indices. Yield, root/stem disease severity, plant height, stem discoloration and microsclerotial densities of M. phaseolina were determined at harvest. When differences between treatments occurred, plants in infested plots had lower stomatal conductance and higher CWSI than those in non-infested plots. Differences between treatments in canopy reflectance were not consistent. In 2008, there was only a genotype effect on yield. In 2009, LS980358 and R01-581F plants had 38 % and 49 % lower yields, respectively, in infested than non-infested plots, whereas yields for DT97-4290 and Delta Pineland 4546 did not differ between infestation treatments. The results from this study show that M. phaseolina affects soybeans at all growth stages and that some genotypes are very sensitive to colonization.

Download or read book Biotic Stress Resistance in Millets written by I. K. Das and published by Academic Press. This book was released on 2016-08-03 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic Stress Resistance in Millets presents an important guide to the disease and pest-related challenges of this vital food crop. Biotic stresses are one of the major constraints for millet production, but newly emerging and forward-thinking problems with disease and insect pests are likely to increase as a result of changing weather, making this an imperative book on best practices. Current strategies are mainly through the development of resistant cultivars, as the use of chemicals is cost-prohibitive to many of those producing millet in developing countries where it is of most value as a food source. This book explores non-chemical focused options for improving plant resistance and protecting crop yield. This single-volume reference will be important for researchers, teachers and students in the disciplines of Agricultural Entomology, Plant protection, Resistance Plant Breeding and Biotechnological pest management. Establishes basic concepts of host resistance providing foundational insight Synthesizes past biotic stress resistance research with the latest findings to orient research for future strategies for plant protection Focuses exclusively on host plant resistance on all major diseases and pests of millets Presents data and strategies that are globally applicable as millets gain importance as a health food
