“…Previous reports (9,21) and our findings suggest that soybean planting date decisions should be based on soil conditions and not the planting date itself. Commercially available fungicide seed treatments are not currently effective against SDS (3,29), so there is not the option of applying treatments to protect seedlings when planting early. Since the cool wet soil conditions that increase root infection are more likely to occur in April than May in Iowa, farmers may choose to plant soybean fields with a history of SDS last in their planting sequence to minimize risk of SDS.…”

Soybean yield losses due to sudden death syndrome (SDS) have varied from year to year in Iowa since the disease was first reported in 1993. An SDS epidemic in 2010 resulted in significant yield losses and raised numerous concerns by farmers and agronomists regarding the potential for future outbreaks. Since infection and SDS development is highly dependent on temperature and soil moisture, our hypothesis was that SDS epidemics occur in years with above-average rainfall and below-average temperatures. To test this hypothesis, environmental conditions in southeast and central Iowa were compared among epidemic and non-epidemic years. Mean total precipitation and number of days with precipitation during each month of the growing season (April through August) tended to be greater in epidemic years (10.4 to 26.3 inches, 10 to 15 days) than non-epidemic years (8.9 to 15.4 inches, 9 to 12 days). Soil temperatures in April through July averaged less in epidemic years (9.0 to 24.7°C) than non-epidemic years (10.4 to 26.6°C). The widespread 2010 SDS epidemic in Iowa likely resulted from the concurrence of several weather conditions that were particularly favorable for disease. To reduce risk of yield losses in future years, soybean farmers should use an integrated disease management for SDS, focusing on using resistant varieties, avoiding soil compaction, and avoiding planting in cool wet soils.

BACKGROUND: Soybean seed treatment with fungicides is a well-established disease management strategy. However, the movement of these fungicides within seedlings is not always well characterized. Thus, the objectives of this study were to determine the pattern of translocation of three fungicides with different modes of action applied as a seed treatment, and the effect of soil type on translocation.RESULTS: Most of the absorbed radioactivity was concentrated in the cotyledons and the maximum sum of the rates of absorption by roots, stems, and leaves of the plants was 15%. In most cases, absorption by roots, stems, and leaves were lower than 5% for 14 C-pyraclostrobin and 14 C-metalaxyl, and 1.6% for 14 C-carbendazim. Fungicides absorbed by the roots and the whole seedlings were higher when plants were grown in soil with lower organic matter content. Fungicides in the cotyledons are unlikely to be redistributed and are lost when cotyledons fall off the plants.CONCLUSION: Cotyledons are the part of the plant where fungicides are most absorbed, regardless of the fungicide. Soil type affects the absorption of fungicides, and in this study it was most likely caused by soil organic matter. These data improve knowledge of the movement of seed treatment fungicides in soybean seedlings and may help the development of seed treatment chemistry to manage seed and soilborne pathogens.

“…Management options of SDS to break the life cycle of the pathogen (Fig. 5) include delayed planting [39,123,135], planting SDS tolerant varieties [102,108], fall tillage [135,137], crop rotation [1,104,137,142], modifying agronomic practices like row spacing and seeding rate [123], fungicide seed treatments [52,72,82,130,131,155], seed treatments with a combination of fungicides, systemic insecticides and biological(s) [2,155], seed treatment with bacteria and fungi based biocontrol agents [43,75,87,129], preplant or foliar applied potassium chloride with fungicides [88], cultural and biological control [4], exploring potential untapped resistance sources in perennial Glycine spp. to improve resistance in soybean [33] and recovering SDS infected plants [79] similar to sorghum and pearl millet [120,121], plant resistance, variety selection, adjusting planting dates, crop rotation, seed treatment with bio-fungicide [149], identification of quantitative trait loci [145], genomic approaches to molecular breeding of resistance [46], integrated approaches [34], clean harvest of corn and soybean [84,151] and genetic engineering along with other traditional management options may be needed as integrated approaches to manage SDS [32].…”

Sudden death syndrome (SDS) caused by Fusarium virguliforme is one of the major yield-limiting soil borne diseases of soybean (Glycine max). The SDS has been reported from 21 U.S. states and is known to occur in Africa, North America, and South America. In the U.S. the losses due to SDS was estimated at $3.06 billion for a period from 1988 to 2010. Since 1983, several management approaches have been investigated to reduce SDS and yet, continued efforts are necessary to develop long term disease management programs and to sustain disease below economic threshold levels. Integrating available control measures is an option, but adaptability and real-world assessments are equally important. Support of several funding agencies to better understand the disease in identifying suitable control measures to reduce yield losses in commercial cultivations has been indispensable in accomplishing these goals. In spite of sustained efforts, SDS continued to spread within the U.S. and reported in seven other countries since its first report in 1971.Comprehensive reviews have previously been published on this disease by Roy et al. [98], Leandro et al. [58], and Hartman et al. [32]. In this review, updated information on geographic distribution and economic significance of SDS, epidemiology, factors affecting SDS, and management options for SDS including screening techniques have been compiled. Also, discussed significant gaps in use of plant, fungi and bacteria based biocontrol agents in addressing management of SDS.Keywords: Soybean sudden death syndrome, SDS, Fusarium virguliforme, biocontrol, global reports, yield losses due to SDS, epidemiological factors, greenhouse and field screening. ______________________________________________________________________________This is a manuscript of an article from CAB Reviews 11 (2016): 039, doi: 10.1079/PAVSNNR201611039. Navi, S. S.; Yang, X. B. 2016. Sudden death syndrome -a growing threat of losses in soybeans. CAB International, Wallingford, UK. Aoki et al., and F. virguliforme,90] is an economically significant soil-borne disease, and a risk to many soybean production areas worldwide. The disease was first observed by H.J. Walters in Arkansas, United States in 1971[100], but it was only in 1983 that the disease was named as sudden death syndrome (SDS) of unknown etiology [40]. As of this review, the disease has been reported in three continents, North America (Canada and United States), South America (Argentina, Bolivia, Brazil, Paraguay, and Uruguay), and Africa (South Africa), and within the United States 21 states (Fig. 1) Whether the pathogens causing SDS have been introduced in to new regions or if they have been present in the soil in production fields of these countries for some time without being detected is unknown. After the SDS was detected in Iowa [150], Scherm and Yang [114] developed a risk assessment model to determine potential geographic range of development of this disease, which was considered a southern disease by then, in North America. They predi...
