چکیده

Fumonisin occurrence was reported in wheat grains and F. proliferatum has been suggested to be the main contributor its presence wheat. Thus, a survey performed order study impact of four commercial fungicides used Argentina for controlling Fusarium head blight disease (epoxiconazole + metconazole, tebuconazole, pyraclostrobin epoxiconazole, prothioconazole) on growth fumonisin production two strains relation water activity (aW; 0.99, 0.97, 0.95) temperature (15 °C 25 °C). Most reduced rates when compared control (reduction increased as fungicide concentration increased), they were at high doses; however, most enhanced sublethal doses, with exception prothioconazole. FHB management could enhance by present grains. En los últimos años se ha observado contaminación de granos trigo con fumonisinas, y postulado como el principal responsable la presencia dicha micotoxina en este cereal. Por motivo, realizó un ensayo manera tal estudiar efecto cuatro formulaciones comerciales fungicidas utilizadas para manejo fusariosis espiga crecimiento producción fumonisinas dos cepas proliferatum, relación actividad agua 0,99; 0,97 0,95) temperatura La mayoría productos fueron capaces reducir velocidad ambas cepas, una mayor acción medida que concentración del fungicida aumentó, también cuando utilizados altas dosis. Sin embargo, elevó estos dosis subletales, excepto aplicó protioconazol. Se concluye comúnmente podrían estimular presentes trigo, llevando así cereal estas micotoxinas.

Wheat kernel black point and fumonisin contamination by Fusarium proliferatum.

Fusarium proliferatum is a major cause of maize ear rot and fumonisin contamination and also can cause wheat kernel black point disease. The primary objective of this study was to determine whether nine F. proliferatum strains from wheat from Nepal can cause black point and fumonisin contamination in wheat kernels. For comparison, the study included three Fusarium strains from US maize. In test...

Survey of fumonisin production by Fusarium species.

Fumonisins B1 (FB1) and B2 (FB2), two structurally related mycotoxins with cancer-promoting activity, were recently isolated from corn cultures of Fusarium moniliforme MRC 826. These toxins have been reported to be produced also by isolates of F. proliferatum. Contamination of foods and feeds by F. moniliforme has been associated with human esophageal cancer risk, and FB1 has been shown to be t...

Production of fumonisin analogs by Fusarium species.

The fumonisins, a family of food-borne carcinogenic mycotoxins, were first isolated in 1988 (21) from cultures of Fusarium verticillioides (Sacc.) Nirenberg (previously known as Fusarium moniliforme Sheldon). During the same year, the structures of the fumonisins were elucidated (6) and fumonisin B1 was shown to cause equine leukoencephalomalacia (34). There have been numerous publications deal...
