“…Yield loss attributed to F. oxysporum has been briefly studied in soybean but results have been mixed. Leath and Carroll (1985) found 48 and 56% yield loss in two soybean cultivars susceptible to Fusarium root rot after inoculation with F. oxysporum , but Díaz Arias et al (2013b) found no difference in yield from inoculated field microplots. Although our results suggested the potential for small yield loss from increasing populations of F. oxysporum , none of the management strategies employed in this study significantly reduced F. oxysporum populations in a way that would potentially mitigate the loss.…”

Fusarium spp. are common fungal pathogens that infect a number of field and vegetable crops. Crop rotation, genetic resistance, and fungicides are the primary methods used for managing these pathogens; however, there is a lack of information regarding the interactions between these management strategies and how they impact Fusarium spp. population dynamics. Therefore, the objective of this research was to quantify the effect of crop rotation and management (i.e., variety selection and fungicide use) on F. graminearum, F. oxysporum, and F. virguliforme populations in the soil using real‐time quantitative polymerase chain reaction (qPCR). Soil samples were collected in 2011 and 2012 from a long‐term corn (Zea mays L.)–soybean [Glycine max (L.) Merr.]–wheat (Triticum aestivum L.) rotation study near Arlington, WI, and populations for each species (spores g−1 of soil) were quantified from extracted soil DNA. Fusarium oxysporum was the most prevalent Fusarium sp. found. Crop rotation and management did not impact F. oxysporum populations nor F. virguliforme presence. A crop rotation by fungicide interaction was found for F. graminearum (P < 0.001), but this interaction was primarily affected by crop rotation. As expected, F. graminearum was found more often in plots with wheat as part of the rotation. This study found few interactions among crop rotation, variety selection, and fungicide use for controlling populations of three Fusarium spp. in the soil, and significant interactions or individual control methods were dependent on the species being examined.

“…Soils (a) and (c) were collected from virgin sites, whereas soils (b) and (d) were from sites that had been in Fusarium wilt-soybean ex-periments for 3 and 10 yr, respectively. Results from previous studies with these soils indicated that the Matapeake-Newark soil was suppressive to Fusarium wilt whereas the Sassafras soil was wilt-conducive (Leath andCarroll, 1982, 1985). Soil (e) came from a site that had been planted with soybean for four consecutive years and had a history of Fusarium wilt occurrence.…”

“…With more than 99 225 ha of soybean cultivated in Delaware in 1983 (Smith, 1985), the necessity for adequate control of this fungal pathogen is imperative. The use of resistant cultivars is an important method 9 of disease control but requires extensive screening of lines, which may be time consuming (Leath andCarroll, 1982, 1985). In the past, application of fungicides to the soil has provided only limited control of soilborne pathogens such as Fusarium.…”

Effect of Biocidal Treatments on Cation Exchange Capacity and Fusarium Blight of Soybean in Delaware Soils

1988

View full text Add to dashboard Cite

Fusarium wilt has caused significant losses in soybean [Glycine max (L.) Merr.] production and is very difficult to control because it is caused by the soil-borne fungus Fusarium oxysporum. A better understanding of the relationship between soil characteristics and the pathogen and between biocidal treatments and physiochemical properties is needed, especially for soils that appear to be suppressive. The effects of autoclaving and Vapam fumigation on cation exchange capacity, organic matter content. clay content, pH, and Fusarium wilt of soybean were determined for several different Delaware soil types (Typic Hapludults, Typic Quartzipsamments, and Typic Umbraqtnults). 'Essex' soybean was grown in the treated soils that had been infested, prior to planting, with 6.3 x 10 4 viable spores per gram of dry soil of a pathogenic Fusarium oxysporum isolate. Treatments were arranged on the greenhouse bench in a randomized completeblock design with five replications. Cation exchange capacity gene•·ally increased with fumigation and decreased with autoclaving, but differences were not significant for all soils. Organic matter content increased following fumigation in three soils, and pH values were lowered by both biocidal treatments in all soils except a Matapeake silt loam. Disease incidence and severity were affected differently for each soil type.Additional index words: Glycine max (L.) Merr., Fusarium oxysporum, Autoclaving, Vapam fumigation, Suppressive soil.

“…Fusarium root and crown rot (FRCR) impact a wide range of economically important crops by causing significant a decrease in crop quality and yield [ 1 , 2 ]. Fusarium resting structures are known to survive harsh winter conditions in soil and crop residues, potentially increasing the susceptibility of subsequently planted crops to FRCR, especially under no-till cropping systems [ 3 , 4 , 5 ].…”

Fusarium root and crown rot (FRCR) negatively impact several economically important plant species. Cover crops host different soil and residue microbiomes, thereby potentially influencing pathogen load and disease severity. The carryover effect of cover crops on FRCR in barley and soybean was investigated. Field trials were conducted in Prince Edward Island, Canada. Two cover crops from each plant group, including forbs, brassicas, legumes, and grasses, were grown in a randomized complete block design with barley and soybean planted in split plots the following year. Barley and soybean roots were assessed for FRCR through visual disease rating and Fusarium spp. were isolated from diseased tissue. Fungal and bacterial communities in cover crop residues were quantified using amplicon sequencing. The disease-suppressive effects of soil were tested in greenhouse studies. The results indicated that sorghum-sudangrass-associated microbiomes suppress Fusarium spp., leading to reduced FRCR in both barley and soybean. The oilseed radish microbiome had the opposite effect, consequently increasing FRCR incidence in barley and soybean. The results from this study indicate that cover crop residue and the associated soil microbiome influence the incidence and severity of FRCR in subsequent crops. This information can be used to determine cover cropping strategies in barley and soybean production systems.
