1. Performance of fungicides on the control of fusarium head blight (Triticum aestivum L.) and deoxynivalenol contamination in wheat grains
RESUMO A giberela é considerada uma doença de difícil controle, num cenário de dificuldades no seu controle químico e pela agressividade do patógeno em produzir toxinas. Diante disso, o objetivo do estudo foi verificar se fungicidas de distintos grupos químicos, isolados ou em mistura são eficazes no controle de giberela e na redução da contaminaç

2. Common resistance to Fusarium head blight in Brazilian wheat cultivars
ABSTRACT: Mycotoxin levels in Fusarium head blight (FHB) infections can be difficult to quantify. The relationship between mycotoxin and disease is not consistent and it is not clear if wheatpathogen interaction is of significance in regions where more than one Fusarium species with distinct trichothecene production ability co-exists. This study aimed to inv

3. MS INTA 416: A new Argentinean wheat cultivar carrying Fhb1 and Lr47 resistance genes
Abstract MS INTA 416 is a hard red winter wheat selected for high yield potential and good bread-making quality, combined with moderate resistance to Fusarium-head-blight and high resistance to leaf-rust, due mainly to presence of resistance genes Fhb1 and Lr47. MS INTA 416 is adapted to main production areas of Central-Argentina.

4. Deoxynivalenol in wheat and wheat products from a harvest affected by fusarium head blight
Abstract Fusarium head blight is an important disease occurring in wheat, caused mainly by the fungus Fusarium graminearum. In addition to direct damage to crops, reduced quality and yield losses, the infected grains can accumulate mycotoxins (toxic metabolites originating from prior fungal growth), especially deoxynivalenol (DON). Wheat crops harvested in 2

5. Single and sequential applications of metconazole alone or in mixture with pyraclostrobin to improve Fusarium head blight control and wheat yield in Brazil
Four fungicide trials were conducted in northern RS state during 2009. Six treatments, from the combination of one (flowering = F) or two applications (F + 10 days) of metconazole sprayed alone or in mixture with pyraclostrobin were tested. Fusarium head blight incidence (INC) and severity (SEV) were assessed at the pre-harvest period and Fusarium-damaged ke

6. Sensitivity of Fusarium graminearum causing head blight of wheat in Brazil to tebuconazole and metconazole fungicides
Fusarium head blight (FHB) of wheat, is caused by fungal populations belonging to the Fusarium graminearum species complex. Although triazole fungicides are widely used in FHB management, information about the sensitivity of F. graminearum populations to such fungicides is scarce, particularly in Brazil. This work aimed at determining the sensitivity of path

7. ReaÃÃo de resistÃncia à giberela em cultivares de trigo (Triticum aestivum L.), avaliada em condiÃÃes de campo e casa de vegetaÃÃo / Reaction of resistance to FHB in wheat cultivars (Triticum aestivum L.) evaluated under field and greenhouse conditions
Caused by several species of fungus, fusarium head blight (FHB) is a disease of great economic importance in wheat (Triticum aestivum L.), causing large losses in world grain production. In Brazil the main species of fungi responsible for disease is Gibberela zeae (Schwabe.), and its the anamorphic Fusarium graminearum (Schwabe). The control by chemical trea

10. Effect of Cultural Practices, Soil Phosphorus, Potassium, and pH on the Incidence of Fusarium Head Blight and Deoxynivalenol Levels in Wheat
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 correla

11. Quantification of Trichothecene-Producing Fusarium Species in Harvested Grain by Competitive PCR To Determine Efficacies of Fungicides against Fusarium Head Blight of Winter Wheat
We developed a PCR-based assay to quantify trichothecene-producing Fusarium based on primers derived from the trichodiene synthase gene (Tri5). The primers were tested against a range of fusarium head blight (FHB) (also known as scab) pathogens and found to amplify specifically a 260-bp product from 25 isolates belonging to six trichothecene-producing Fusari

12. Occurrence of Beauvericin and Enniatins in Wheat Affected by Fusarium avenaceum Head Blight†
We evaluated Fusarium contamination and the levels of hexadepsipeptide mycotoxins in 13 wheat samples affected by head blight in Finland. Fusarium avenaceum was the dominant species (91%) isolated from all samples, but isolates of F. culmorum (4%), F. tricinctum (3%), and F. poae (2%) also were recovered. Beauvericin (0.64 to 3.5 μg/g) was detected in all 1
