Fusarium spp. Causing Dry Rot of Seed Potato Tubers in Michigan and Their Sensitivity to Fungicides.
A survey of seed potato tubers in Michigan seed production storage facilities was carried out during 2009 and 2010. Fusarium spp. associated with tuber dry rot symptoms were identified to species and…

First Report Of Strobilurin Resistance In Cercospora Beticola In Sugar Beet (Beta Vulgaris) In Michigan And Nebraska, USA
Cercospora leaf spot (CLS) caused by Cercospora beticola Sacc. is the most important foliar disease of sugar beet ( Beta vulgaris ) worldwide (Jacobsen & Franc, 2009). CLS is controlled mainly with…

To the authors' knowledge, this is the first report of resistance to fludioxonil in isolates of F. sambucinum and F. oxysporum in Michigan, and the occurrence of such isolated strains necessitates the development of partner chemistries that can preempt any future concerns on lack of performance of products in use.
First Report of Fusarium torulosum Causing Dry Rot of Seed Potato Tubers in the United States.
This is the first report of F. torulosum causing potato dry rot in the United States and the closest match (99%) to previously sequenced materials was obtained to the NCBI database.
Tuber Blight Development in Potato Cultivars in Response to Different Genotypes of Phytophthora infestans
Management of late blight caused by isolates of P. infestans designated US-22 through host resistance may be feasible but imposes a different set of criteria for consideration from those that US-8 imposed.
Effect of Different Genotypes of Phytophthora infestans (Mont. de Bary) and Temperature on Tuber Disease Development
The US-8 genotype isolates were the most aggressive in tubers in most years causing rapid and significantly more tuber damage than any other genotype of P. infestans and similar to the US-6, US-10 and US-14 isolates used in 2006.
