Fig. 1. Principal components analysis (PCA) of Cercospora janseana isolates collected from Louisiana and Texas. Principal component (PC) 1 is shown on the x axis, and PC2 is shown on the y axis. Each circle represents a single isolate and is color-coded based on the respective sampling population. The PCA was conducted with 50,000 random variants.
Jacob Searight et al. used whole-genome sequencing of 136 #Cercospora janseana isolates collected from Louisiana and Texas to investigate genetic diversity, population structure, and possible reproductive strategies: https://doi.org/10.1094/MPMI-03-25-0031-R

IGURE 1 Michigan counties sampled for sugarbeet leaves symptomatic with Cercospora leaf spot in 2021 to 2022 (highlighted in gray): Arenac, Bay, Clinton, Gratiot, Huron, Midland, Saginaw, Sanilac, and Tuscola. Field locations indicated with open circles for 2021 and filled triangles for 2022. Map generated using the ‘ggplot’ package (Wickham 2016) in R Statistical Software (v.4.1.1; R Core Team 2021) using methods from McCoy (2021).
Sugarbeets produce over half of domestic sugar in the United States, and Michigan is the fourth-highest U.S. producer. Alexandra P. Hernandez et al. characterized fungicide resistance in #Cercospora beticola populations from #sugarbeet in MI: https://doi.org/10.1094/PHYTOFR-03-25-0028-R

Fig. 1. A, Whole table beet seeds. B, A table beet seed dissected into the pericarp, operculum, true seed, and testa. C, Parts of the dissected table beet seed placed on a plate of clarified V8 juice agar medium.
Editor’s Pick: Cercospora leaf spot (CLS) is a key determinant of table beet foliar health. Pratibha Sharma et al. evaluated localization of #Cercospora beticola in table beet seeds and how infested seeds drive CLS outbreaks in field studies: https://doi.org/10.1094/PDIS-12-24-2624-RE

Bieteninstituut IRS waarschuwt voor hoge infectiewaarden van cercospora in gesloten bietenpercelen in meerdere regio's. De eerste vlekjes worden over tien tot achttien dagen verwacht. Telers kunnen dus tijdig maatregelen nemen. #cercospora
