Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user's needs and established successful practice. In 2013, Fusarium community voiced near unanimous support for concept of represented clade comprising all agriculturally clinically important species, including F. solani species complex (FSSC). Subsequently, this was challenged in 2015 one research group who proposed dividing genus into seven genera, FSSC described as members...

Seedling (caused various pathogens), Sclerotinia stem rot (white...
Sudden death syndrome (SDS) is a serious threat to soybean production that can be managed with host plant resistance. To dissect the genetic architecture of quantitative resistance disease in soybean, two independent association panels elite cultivars, consisting 392 and 300 unique accessions, respectively, were evaluated for SDS multiple environments years. The genotyped 52,041 5,361 single nucleotide polymorphisms (SNPs), respectively. Genome-wide mapping was carried out using mixed linear...
Sclerotinia stem rot (also known as white mold) of soybean is a significant yield-limiting problem in the North Central production region. This disease, caused by fungus sclerotiorum (Lib.) de Bary, varies incidence and severity from year to because its sensitivity weather conditions. Losses can be substantial when environmental conditions management practices favor high yield potential. Employing disease plan based on knowledge field history best help reduce losses rot. An effective...
Annual reductions in corn (Zea mays L.) yield caused by diseases were estimated university Extension-affiliated plant pathologists 26 corn-producing states the United States and Ontario, Canada, from 2016 through 2019. Estimated loss each disease varied greatly state or province year. Gray leaf spot (caused Cercospora zeae-maydis Tehon & E.Y. Daniels) greatest parts of northern Ontario all years except 2019, Fusarium stalk rot spp.) also reduced yield. Tar Phyllachora maydis Maubl.), a...
Oomycete pathogens are commonly associated with soybean root rot and have been estimated to reduce yields in the United States by 1.5 million tons on an annual basis. Limited information exists regarding frequency diversity of oomycete species across major soybean-producing regions North America. A survey was conducted 11 states province Ontario, Canada. In 2011, 2,378 cultures were isolated from seedling roots a semiselective medium (CMA-PARPB) identified sequencing internal transcribed...
Soybean (Glycine max (L.) Merr.) is produced across a vast swath of North America, with the greatest concentration in Midwest. Root rot diseases and damping-off are major concern for production, primary causal agents include oomycetes fungi. In this study, we focused on examination oomycete species distribution soybean production system how environmental soil (edaphic) factors correlate community composition at early plant growth stages. Using culture-based approach, 3,418 isolates were...
Neonicotinoids are the most widely used insecticides worldwide and typically deployed as seed treatments (hereafter NST) in many grain oilseed crops, including soybeans. However, there is a surprising dearth of information regarding NST effectiveness increasing soybean yield, published data suggest weak, or inconsistent yield benefit. The US key soybean-producing nation this work includes from 194 randomized replicated field studies conducted specifically to evaluate effect NSTs on at sites...
Abstract Soybean (Glycine max L.) is a major crop grown in the United States but susceptible to many diseases that cause significant yield losses each year. Consistent threats exist across both northern and southern production regions include soybean cyst nematode, charcoal rot, seedling diseases. In contrast, like Phytophthora stem root sudden death syndrome, Sclerotinia rot (white mold) are intermittent can be heavily influenced by environmental factors. Additional have emerged recent...
Soil biota have important effects on crop productivity, but can be difficult to study in situ. Laser ablation tomography (LAT) is a novel method that allows for rapid, three-dimensional quantitative and qualitative analysis of root anatomy, providing new opportunities investigate interactions between roots edaphic organisms.
