“…Most F. asiaticum on maize in Asia produce NIV (Desjardins and Proctor, 2011;Lee et al, 2012;Ndoye et al, 2012), while F. meridionale and F. boothii isolates seem to be fixed for NIV and 15-ADON production, respectively. This is comparable to reports from samplings in South Africa, Nepal and Argentina (Boutigny et al, 2011;Desjardins and Proctor, 2011;Sampietro et al, 2011). In China, Ndoye et al (2012) reported that on maize F. asiaticum with the NIV chemotype dominated in warmer regions while F. graminearum with the 15-ADON chemotype is dominant in cooler regions.…”

“…On maize in South Africa only Fusarium boothii was found (Boutigny et al, 2011). In Nepal, the predominant species on maize were Fusarium meridionale and Fusarium asiaticum (Desjardins and Proctor, 2011), while F. meridionale was also predominant in Argentina (Sampietro et al, 2011). In South Korea, four species within the FGSC were associated with FER and F. graminearum was predominant .…”

In recent years increasing demands and the relatively low-care cultivation of the crop have resulted in an enormous expansion of the acreage of maize in China. However, particularly in China, Fusarium ear rot forms an important constraint to maize production. In this study, we showed that members of both the Fusarium fujikuroi species complex (FFSC) and the Fusarium graminearum species complex are the causal agents of Fusarium ear rot in the main maize producing areas in China. Fumonisin producing Fusarium verticillioides was the most prevalent species, followed by fumonisin producing Fusarium proliferatum and 15-acetyldeoxynivalenol producing F. graminearum. Both Fusarium temperatum and Fusarium boothii were identified for the first time in the colder regions in China, extending their known habitats to colder environments. Mating type analysis of the different heterothallic FFSC species, showed that both types co-occur in each sampling site suggestive of the possibility of sexual recombination. Virulence tests with F. boothii (from maize) and F. graminearum from maize or wheat showed adaptation to the host. In addition, F. graminearum seems to outcompete F. boothii in wheat-maize rotations. Based on our findings and previous studies, we conclude that wheat/maize rotation selects for F. graminearum, while a wheat/rice rotation selects for F. asiaticum. In contrast, F. boothii is selected when maize is cultivated without rotation. A higher occurrence of F. temperatum is observed on maize in colder climatological regions in China, while Fusarium meridionale seems restricted to mountain areas. Each of these species has their characteristic mycotoxin profile and deoxynivalenol and fumonisin are the potential threats to maize production in Northern China.

“…Estos resultados son nóveles y discrepan de estudios previos, que afirman que el deoxinivalenol, sus acetilados y nivalenol producidos por F. graminearum eran dominantes en el área de trigo de Argentina (Reynoso et al, 2011;Sampietro et al, 2011). Estos también proporcionan una perspectiva distinta sobre la producción de diferentes tipos de micotoxinas en el país.…”

Resumen -El objetivo de este trabajo fue evaluar la presencia de micotoxinas en las harinas derivadas de trigo y soja expuestos a la infección de Fusarium graminearum y detectadas por prueba de Elisa. La contaminación fue evaluada durante 2010 y 2012, en condiciones de invernadero, a través de inoculaciones artificiales, y en lotes de producción en campo, expuestos a infecciones naturales. Se utilizaron 26 muestras de harinas derivadas de cariopsis de trigo y semillas de soja. La detección de micotoxinas deoxinivalenol y zearalenona se realizó por kit de Elisa. En harinas de trigo de diversos ambientes, se detectaron ambas micotoxinas -deoxinivalenol y zearalenona -, mientras que en harinas de soja sólo se detectó zearalenona. Las concentraciones de esas micotoxinas observadas en las harinas no son admisibles para el consumo humano y animal. El kit de Elisa constituyó una herramienta biotecnológica efectiva para la detección de la contaminación predominante de zearalenona, producida por F. graminearum, en harinas de trigo y soja de diferentes ambientes semicontrolados y naturales.Términos para indexación: Fusarium graminearum, Glycine max, Triticum aestivum, deoxinivalenol, zearalenona. Mycotoxins in flours derived from wheat and soybean detected by the Elisa testAbstract -The objective of this work was to evaluate the presence of mycotoxins in flours derived from wheat caryopses and soybean seed exposed to Fusarium graminearum infection and detected by the Elisa test. Contamination was evaluated during 2010 and 2012, in greenhouse conditions, by artificial inoculation, and on field-production batches exposed to natural infections. Twenty-six samples of flours derived from wheat caryopses and soybean seeds were used. Detection of the mycotoxins deoxynivalenol and zearalenone was performed by an Elisa kit. In wheat flour of different environments both mycotoxins -deoxynivalenol and zearalenone -were detected, while in soybean flour only zearalenone was detected. Mycotoxins concentrations observed in these flours are inappropriate for human and animal consumption. Elisa kit constituted an effective biotechnological tool for the detection of prevailing contamination by zearalenone, caused by F. graminearum in wheat and soybean flours of different, semicontrolled and natural environments.

Various pathogenic microorganisms affect plants. However, most diseases are caused by fungi, which have an enormous reproductive capacity and possess metabolic mechanisms capable to develop resistance to commercial fungicides. Fungi produce mycotoxins on crops and this represents a considerable risk to human and animal health. The most important genera of phytopathogenic fungi of the American continent are: Aspergillus, Alternaria, Botrytis, Colletotrichum, Fusarium, Phytophthora, Penicillium and Pythium, among others. Different strategies have been used for phytopatogenic fungi control, mainly by using synthetic fungicides. Currently, a great deal of attention has been paid towards exploitation of higher plant products as an innovative alternative in crops protection. The use of plant derived natural products has many advantages, such as little or no harmful side effects, rare cases of resistance, long-term control and completely or substantially eliminates the use of synthetic fungicides. Several plants belonging to the Anacardiaceae, Asteraceae, Caprifoliaceae, Lamiaceae, Liliaceae, Papilionacea, Poaceae, Verbenaceae, families, have showed fungicide potential. Therefore, this review addresses occurrence of the most important phytopatogenic fungi and the current state of research regarding the potential of vegetable biodiversity in the development of plant derived natural products for the management of these pathogens in the American continent.
