Book Synopsis Effect of Fungicide Seed Treatments on Fusarium Virguliforme and Development of Sudden Death Syndrome in Soybean by : Japheth D. Weems

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sudden death syndrome (SDS) is a soilborne disease responsible for causing significant yield reductions across soybean-producing states. Recent research indicates that infection of the soybean radicle early in the season by Fusarium virguliforme (Fv), the SDS pathogen, is critical for disease development. This suggests fungicide seed treatments could be effective in limiting early infection possibly resulting in disease control. Field, greenhouse, and laboratory studies were conducted to evaluate eight fungicides in multiple seed treatment combinations for effects on Fv infection and SDS development. Seed treatments were applied to cultivars that were moderately resistant and moderately susceptible to SDS. Field studies were conducted at two locations: in 2008, the Valmeyer, IL location was naturally infested with Fv, and in 2008 and 2009 the Urbana, IL location had a natural Fv infestation and soil was augmented with sterilized grain sorghum colonized by Fv. Similarly, the greenhouse study was inoculated with sterilized, Fv infested grain sorghum to evaluate the same seed treatments on moderately resistant and moderately susceptible cultivars. The rolled-paper towel laboratory assay tested the individual fungicides in the growth chamber using a Fv macroconidial suspension to inoculate treated seed and assess effects on seed germination, plant length, lesion size, and disease severity. Fv DNA concentrations in soybean roots were measured using quantitative polymerase chain reaction (qPCR) in early vegetative stage roots. Soybean roots from the field were collected at three timings for digital scanning and analysis with root analysis software to measure root disease symptoms. Roots were scanned and analyzed at the completion of the greenhouse trial. SDS foliar symptoms were rated several times throughout plant growth and the area under disease progress curve (AUDPC) was calculated. Harvest data were collected for the field study. In the field, seed treatments had no effect on Fv DNA concentrations in roots. Seed treatments had very little effect on roots analyzed from the field. Most seed treatments did significantly decrease SDS foliar symptoms at the Valmeyer field study compared to the control, but no differences in foliar symptoms were observed for the Urbana field studies. Yield was unaffected by seed treatments. In the greenhouse, Fv DNA concentrations were reduced by a treatment combining mefenoxam + thiophanate-methyl + azoxystrobin + B. pumilus + prothioconazole + fludioxonil compared to the non-treated control; however, the reduction in Fv DNA did not improve root growth or decrease SDS foliar symptoms compared to the non-treated control. The Fv DNA concentrations in roots did not significantly correlate to SDS foliar symptoms in the field; however, a significant positive correlation was found in the greenhouse between Fv DNA and SDS foliar symptoms. Several seed treatments decreased lesion length and disease severity compared to the non-treated inoculated control in the rolled-towel laboratory assay, but the biological seed treatment, B. pumilus, significantly decreased seed germination and plant length while increasing lesion length and SDS severity compared to the non-treated inoculated control. In conclusion, none of the seed treatments evaluated proved to have consistent effects on Fv or SDS.

Book Synopsis Effect of Soybean Seed Treatments on Oomycete Evolution and Diversity for Improved Seedling Disease Management by : Zachary Albert Noel

This book was released on 2019 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean (Glycine max L.) is the second most important crop in the United States. Soil conservation efforts combined with earlier planting dates has led to increased crop residue and cooler soil at planting. This exposes seeds and developing seedlings to adverse conditions for extended periods of time, which can increase disease pressure from many oomycete pathogens causing pre- or post-emergence damping-off. In North America, at least 84 oomycete species within the genera Pythium, Phytophthora, Phytopythium, and Aphanomyces are associated with soybean seedlings. The number of oomycete species makes management decisions difficult and seed applied anti-oomycete chemicals (oomicides) are the primary management tool against the majority of these species. Therefore, the overall theme of this dissertation was to determine the effect of soybean seed treatments on oomycete evolution and diversity to improve management recommendations. First, in chapter 1, I provide a review of current literature and background information on soybean seedling disease management, fungicide (including oomicide) resistance theory, Peronosporalean taxonomy and evolution, and review current methods to study oomycete diversity. Secondly, since an essential step in monitoring for oomicide resistance is in vitro testing, I provide clarification of terms and models involved in the analysis of in vitro dose-response data for improved reproducibility (chapter 2). Next, in chapter 3, the level of interspecific variation in mefenoxam and ethaboxam sensitivity was determined using a newly developed high-throughput assay for oomycetes that utilized growth curves and Z'-factor for quality control. This revealed that that interspecific variation in sensitivity to ethaboxam was greater than mefenoxam. Therefore, in chapter 4, the genetic and evolutionary mechanism of ethaboxam insensitivity was investigated. This revealed for the first time that inherent insensitivity to ethaboxam was linked to the convergent evolution of a specific substitution in the target gene, which resulted in lineage-specific insensitivity to ethaboxam. In chapter 5, the effect of location, and seed treatments containing either mefenoxam or ethaboxam and metalaxyl on the recovery of oomycetes from soybean taproot or lateral root tissue. This study demonstrated that oomycete communities were largely structured by location and that the recovery oomycetes from soybeans were dependent on the unique combination of location, tissue, and seed treatment. Finally, in chapter 6, an oomycete metabarcoding approach (amplicon sequencing) was used to study the influence of soybean seed treatment and genotype on oomycete rhizosphere diversity from a location with or without a history of seedling disease. This indicated that oomycete community diversity was driven by location and that an imbalance of oomycete taxa rather than simply the presence-absence of certain taxa might be responsible for differences in disease pressure. Additionally, there was no substantial evidence that genotype or seed treatment influenced oomycete diversity in soybean rhizosphere samples. Finally, in chapter 7, I discuss the overall conclusions and impacts of the studies presented herein. Overall, data from these studies provide essential new information for the management of oomycete communities with soybean seed treatments. Importantly, these studies advance our knowledge about the effect of soybean seed treatments on the evolution and diversity of oomycetes in a soybean agroecosystem.
