“…Although ZEA occurrence in pasture forage in Europe can also be expected (Summerell et al, 2010;Szécsi et al, 2013) (Engels and Krämer, 1996;Golinski et al, 2003;Skládanka et al, 2011). Furthermore, above mentioned studies has been performed on pastures intended for intensive pasture-based systems or on experimental swards composed of high-producing grasses belonging to genus Lolium, Festuca or Poa and/ or their hybrids or mixtures.…”

The aim of the study was to estimate the forage quality and mycotoxin contamination in the locality of Švýcárna (1304 m a.s.l.), where the cattle grazing a er the long-term management cessation was introduced on the pasture area of 3.6 ha in 2012. The pasture was divided into two grazing plots: P1 (Nar) (dominance of Nardus stricta) and P2 (Des) (dominance of Deschampsia cespitosa). Samples of forage were taken in June, July, August and September 2014 and 2015 from fi ve permanent plots situated in diff erent places of locality. Samples were analysed on the content of basic nutrients and macroand micro-elements. Further, the content of deoxynivalenol (DON), zearalenone (ZEA) and T-2/ HT-2 toxin was determined using ELISA method. From June to September the mean content of crude fi bre signifi cantly (P < 0.05) increased (from 243.9 g.kg −1 DM to 331.7 g.kg −1 DM, respectively) and the content of crude protein signifi cantly (P < 0.05) decreased (from 166.9 g.kg −1 DM to 89.2 g.kg −1 DM, respectively). Mean concentration of DON in P1 (Nar) was numerically higher than in P2 (Des), being 715 and 620.63 μg.kg −1 , respectively (P < 0.05). Mean concentration of T-2/HT-2 toxin was 44.88 and 55.04 μg.kg −1 in P1 (Nar) and P2 (Des), respectively. The content of ZEA in P1 (Nar) of 54.65 μg.kg −1 was lower than in P2 (Des) being 78.72 μg.kg −1 (P < 0.05).

“…In the last decade, some studies have used this approach to reveal patterns of genetic diversity in the plant pathogens Phakopsora pachyrhizi (Freire and Oliveira, 2008), Erysiphe necator (Brewer and Milgroom, 2010), and Fusarium sp (Summerell et al, 2010), but for L. theobromae, still now, there is a lack around phylogeographic studies.…”

ABSTRACT. Lasiodiplodia theobromae is a plant pathogen with a worldwide distribution, with low host specificity, causing stem cankers, dieback diseases, and fruit rot in several species of plants. In coconut, this pathogen is reported as the etiological agent of "coconut leaf blight" (CLB) disease, causing several losses in fruit production. The CLB is an important disease for this crop in Brazil. In our study, we used a phylogeographic approach through the molecular characterization of the translation elongation factor 1-α (TEF1-α) to elucidate the pathogen distribution in Brazil and other countries, besides, search information about diversity sources of this pathogen in coconut palm tree at Brazilian northern, northeast, and southeast. We found that L. theobromae diversity is within populations (locations), and populations that are located closest to the center of the tropical zone have more variability as Central Africa, Brazilian Southeast, and Northeast. The widespread distribution could be in part related with long-distance dispersal via global trade of plants and plant products. The entrance route of L. theobromae in Brazil probably occurred from Africa route and not occurred once. In Brazil, the diversity of this pathogen in coconut tree could be linked to two agents of selection: high host diversity (in Northeast) and distinct management measures adopted in Southeast. These different sources of selection, mainly the mutations, could be one of the reasons that we found distinct reactions to "coconut leaf blight" chemical control in these regions.

Dry rot is a serious potato disease and causes significant losses in China. Research efforts on potato dry rot have been very limited as well as the attempts to characterize the pathogen in the major potato production regions of China. A total of 260 Fusarium isolates were identified in 698 potato tubers collected in six important potato production regions of northern China, out of which five different Fusarium species, Fusarium sambucinum, F. avenaceum, F. oxysporum, F. equiseti, and F. acuminatum, were isolated. The identification of each species was confirmed by sequencing analysis of ∼700 bp DNA fragment derived from the translation elongation factor-1 alpha gene. F. sambucinum was found to be the predominant species accounting for 56% of the isolates. Different pathogenicity was found to be associated with five most common Fusarium species. Sixty-seven clones used in China were identified as susceptible to F. sambucinum, indicating little scope for developing resistant cultivars using the currently available potato germplasm.
