Soybean Cultivar Responses to Sclerotinia sclerotiorum in Field and Controlled Environment Studies.
The results from this study suggest that determination of levels of soluble pigments in stems, measurement of lesion lengths on stems discolored by oxalic acid, and the detached leaf assay may be better than mycelial inoculation of stems or foliage in evaluating soybean cultivars for field resistance to S. sclerotiorum.

  • 1 November 2012
Examination of factors that influence DON accumulation in small grain cereals from an agricultural perspective can be used to develop strategies that reduce Don accumulation in grain before harvest and to mitigate the human and animal health risks associated with DON contamination of food and feed.

An Eriophyid Mite-Transmitted Plant Virus Contains Eight Genomic RNA Segments with Unusual Heterogeneity in the Nucleocapsid Protein
It is the first report to demonstrate that emaraviruses produce subgenomic-length mRNAs that are most likely utilized for genome expression and the examination of gene functions and virus diversity and the development of effective diagnostic methods and management strategies for an economically important but poorly understood virus. Expand
Effects of Integrating Cultivar Resistance and Fungicide Application on Fusarium Head Blight and Deoxynivalenol in Winter Wheat.
Fusarium head blight or scab, incited by Fusarium graminearum, can cause significant economic losses in small grain production and fungicide efficacy in reducing FHB and DON was greater in moderately resistant cultivars than in susceptible ones. Expand
Germination and Sporulation of Colletotrichum acutatum on Symptomless Strawberry Leaves.
It is suggested that appressoria and secondary conidia of C. acutatum produced on symptomless strawberry foliage may be significant sources of inoculum for fruit infections. Expand
Management of Fusarium head blight of wheat and barley
This review examines these techniques individually and emphasizes the integration of two or more of them to optimize the effectiveness of managing FHB and DON during the growing season. Expand
Influence of Temperature and Wetness Duration on Conidia and Appressoria of Colletotrichum acutatum on Symptomless Strawberry Leaves.
Production of secondary conidia and appressoria of C. acutatum on symptomless strawberry leaves under a range of environmental conditions suggests that these processes also occur under field conditions and contribute to inoculum availability during the growing season. Expand
Efficacy and Stability of Integrating Fungicide and Cultivar Resistance to Manage Fusarium Head Blight and Deoxynivalenol in Wheat.
Although the magnitude of percent control will likely vary among environments, integrating a single tebuconazole + prothioconazole application at anthesis with cultivar resistance will be a more effective and stable management practice for both index and DON than either approach used alone. Expand
Wheat cultivar-specific disease synergism and alteration of virus accumulation during co-infection with Wheat streak mosaic virus and Triticum mosaic virus.
It is suggested that WSMV and TriMV induced cultivar-specific disease synergism in Arapahoe, Tomahawk, and Mace, and these findings could have several implications for management of wheat viruses in the Great Plains. Expand
Strawberry Plant Extracts Stimulate Secondary Conidiation by Colletotrichum acutatum on Symptomless Leaves.
The results suggest that inoculum levels of C. acutatum on foliage may increase during flowering of strawberry plants, and application of flower extracts resulted in up to 10- and 16-fold increases in conidia on leaves and coverslips, respectively. Expand
