Decline in deoxynivalenol (vomitoxin) concentrations in 1983 ontario winter wheat before harvest.
نویسندگان
چکیده
Samples of winter wheat were collected in 1983 from five fields in southwestern Ontario that were naturally infected with head blight. The geometric mean concentration of deoxynivalenol (vomitoxin) in the grain declined significantly from 1.56 mug/g on 7 July to 0.21 mug/g on 14 July and 0.11 mug/g on 18 July and did not increase at harvest (20 through 27 July).

Forecasting of Fusarium head blight and deoxynivalenol content in winter wheat with FusaProg
Fusarium head blight is one of the most serious cereal diseases of the world. Epidemics of Fusarium head blight can lead to a decline in grain quality and yield. In addition, grains often become contaminated with mycotoxins, which are harmful to humans and animals. In a field survey of winter wheat in Switzerland, Fusarium graminearum proved to be the most prevalent species responsible for head...

In a survey conducted in 1984 in Essex, Lambton, and Middlesex Counties of Ontario, Canada, greater incidences of head blight and greater concentrations of deoxynivalenol in grain were observed in fields of winter wheat planted after corn than in those planted after soybeans, barley, and mixed grains. Neither head blight nor deoxynivalenol level were correlated significantly with soil P, K, or ...

Fifty 12,13-epoxytrichothecenes have been reported in the literature; of these diacetoxyscirpenol, T-2 toxin, nivalenol and vomitoxin have been naturally occurring in cereal grains throughout the world. Vomitoxin is produced in ears of corn prior to harvest when wet, cool weather precedes which favours Gibberella zeae growth. This type of infected corn, which often contains vomitoxin, is associ...

Deoxynivalenol (DON, vomitoxin) is a natural-occuring mycotoxin mainly produced by Fusarium graminearum, a food-borne fungi widely distributed in crops and it is one of the most important mycotoxins in wheat and wheat-based foods and feeds. DON affects animal and human health causing diarrhea, vomiting, gastro-intestinal inflammation, and immunomodulation. Since the rate of the occurrence of DO...

Fusarium Head Blight (FHB) emerged in the 1990’s as an important problem for American agriculture. Resolving the FHB problem involves cooperative efforts and a multidisciplinary approach, including analytical assays for vomitoxin in the new wheat and barley varieties. In 1999, the US Wheat and Barley Scab Initiative provided grants, for diagnostic vomitoxin (DON) services, to 4 laboratories in ...
