| trichothecenes and mycoflora in wheat harvested in nine locations in buenos aires province, argentina. | a total of 120 freshly harvested wheat samples from the 2004 season in nine locations from northern buenos aires province, argentina, were analysed for trichothecene natural occurrence and associated mycoflora, and for determining the influence of commonly used fungicide field treatment and the cultivar type on trichothecene contamination. the trichothecenes t-2 tetraol, t-2 triol, ht-2 and t-2 toxin (ht-2, t-2), diacetoxyscirpenol (das), nivalenol (niv), deoxynivalenol (don), 3-acetyldeoxynival ... | 2008 | 18266077 |
| fusarium graminearum and deoxynivalenol contamination in the durum wheat area of argentina. | fusarium graminearum head blight of wheat is a destructive disease of the world's wheat-growing areas. this work was performed to analyze the distribution and contamination of deoxynivalenol (don) and its relationship with f. graminearum kernel invasion in argentina durum wheat area during two consecutive harvests. a total of 147 samples (cultivars and lines) of durum wheat from 5 locations of the major cropping area (southern buenos aires province) were analyzed. percentage of f. graminearum ke ... | 2003 | 12608577 |
| [identification of the mycotoxin zearalenone in argentina]. | zearalenone, an estrogenic toxin produced by several fusarium sp., was detected by two chromatographic methods in grain and food samples from several farms of th buenos aires province. suspected zearalenone spots were identified by comparing their rf against that of the pure substance, by their change of behaviour under ultraviolet light of different wavelengths, by comparing the rf against a standard preparation after thin layer chromatography in four different solvent systems, and by color rea ... | 1980 | 6216499 |
| characterization of novel trichoderma spp. isolates as a search for effective biocontrollers of fungal diseases of economically important crops in argentina. | monoconidial cultures of 33 isolates of trichoderma from buenos aires province, argentina were characterized on the basis of twenty eight morphological, physiological and biochemical features. all of them were screened for proteinase, endochitinase and β-1,3 glucanase activity. universally primed pcr (up-pcr) and inter-simple sequence repeat (issr) techniques were used to examine the genetic variability among isolates, which resulted in 127 bands for the total number of isolates. these results w ... | 2011 | 22805919 |
