Fungicides Application against Fusarium Head Blight in Wheat and Barley for Ensuring Food Safety
Fusarium head blight (FHB), or scab, caused by several Fusarium species, especially Fusarium graminearum Schwabe [teleomorph Gibberella zeae (Schweinitz) Petch], is a widespread and destructive disease of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and other small-grain cereals (Liddell 2003; Parry et al. 1995; Pirgozilev et al. 2003). These pathogens infect spikes and reduce gra...
متن کاملMapping and Expression Analysis of a Fusarium Head Blight Resistance Gene Candidate Pleiotropic Drug Resistance 5 (PDR5) in Wheat
Fusarium head blight (FHB) caused by Fusarium graminearum is a serious disease of wheat (Triticum aestivum L.), through which grain quality losses are induced by fungal trichotecene mycotoxins such as deoxynivalenol (DON). A class of plasma membrane localized ABC transporter proteins related to the yeast PDR5 (pleiotropic drug resistance5) efflux pump seems to be responsible for partial resista...
متن کاملEnzymatic detoxification of Don in transgenic plants via expression of Fusarium graminearum Tri101 gene
Fusarium graminearum is causal agent of economically catastrophic disease of cereal Fusarium Head Blight (FHB) around the world. In addition to causing a loss of yield, this fungus causes serious threats to humans and animals due to the contamination of grain with the trichothecene mycotoxin. TRI101 gene, a Fusarium spp. gene, encodes an enzyme that transfers an acetyl group to the C3 hydroxyl ...
متن کاملForecasting 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...
متن کاملEvaluation of different fungicides for control of fusarium head blight in wheat inoculated with 3ADON and 15ADON chemotypes of Fusarium graminearum in Canada
Fusarium head blight (FHB) continues to threaten the economic sustainability of many small grain producers in Manitoba by causing losses in grain yield and quality. In this 2-year study, four fungicides were tested on two spring wheat cultivars with different levels of resistance to FHB inoculated with 3ADON and 15ADON chemotypes of Fusarium graminearum. All fungicides (prothioconazole, tebucon...
