COST-BENEFIT AND STATISTICAL ANALYSIS OF FUNGICIDES FOR SUPPRESSION OF FUSARIUM HEAD BLIGHT (SCAB) IN HARD RED SPRING WHEAT IN 1997 AgEcon
Haugen, Ronald H.; Aakre, Dwight G..
A cost-benefit and statistical analysis of fungicides for suppression of fusarium head blight (scab) in hard red spring wheat was completed on data from physical experiments done in Fargo and Carrington, North Dakota in 1997. Various fungicide data were analyzed by applying revenues and costs to the experiment yields to determine net revenue. The net revenues were analyzed statistically using a one-way ANOVA (analysis of variance). No statistical difference was found between the control and other treatment with the Fargo data. There was a statistical difference between the control and other treatments with the Carrington data. The data sets were combined and analyzed; location proved to be a significant factor.

Deoxynivalenol in wheat and wheat products from a harvest affected by fusarium head blight Ciênc. Tecnol. Aliment.
MACHADO,Lidiane Viera; MALLMANN,Carlos Augusto; MALLMANN,Adriano Olnei; COELHO,Raquel Durand; COPETTI,Marina Venturini.
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 2014/2015 in southern Brazil were affected by high levels of Fusarium head blight. In this context, the aim of this study was evaluate the mycotoxicological quality of Brazilian wheat grains and wheat products (wheat flour and wheat bran for DON. DON contamination was evaluated in 1,504 wheat and wheat product samples produced in Brazil during 2014. It was determined by high performance liquid...

Detecção de Giberela em trigo usando processamento digital de imagens na banda do infravermelho próximo. Infoteca-e
BARBEDO, J. G. A.; TIBOLA, C. S.; FERNANDES, J. M. C..
Dentre as principais doenças que atacam o trigo, a giberela é de particular interesse. Esta doença, além de causar perdas na produção, está associada também à presença da micotoxina chamada deoxinivalenol, a qual pode causar sérios problemas de saúde em pessoas e animais.

Detecting wheat Fusarium head blight using hyperspectral imaging. Repositório Alice
BARBEDO, J.; TIBOLA, C.; FERNANDES, J. M..
The objective of this study was to detect FHB in wheat kernels using HSI. An algorithm, based on mathematical morphological operations and linear thresholding, was developed and implemented in order to be both simple and accurate.

IMPACTS OF DON IN THE MALTING BARLEY SUPPLY CHAIN: AGGREGATE COSTS AND FIRM-LEVEL RISKS AgEcon
Johnson, D. Demcey; Nganje, William E..
DON is a toxic byproduct of fusarium head blight (FHB), a fungal disease of small grains. Beginning in 1993, a prolonged outbreak of FHB occurred in the Upper Midwest, the traditional source of most six-rowed malting barley produced in the United States. Price discounts associated with DON in barley have been significant. This paper has two objectives. The first is to estimate the impact of DON on the value of malting barley grown in the Upper Midwest. Using crop quality data, we use a linear programming model to derive optimal blends of barley supplies, given discount schedules and the distribution of quality factors. The premise is that blending activities, on a regional scale, allow a larger fraction of the crop to be sold as malting. The second...

Mapping a QTL conferring resistance to Fusarium head blight on chromosome 1B in winter wheat (Triticum aestivum L.) OAK
Nishio, Zenta; Orme, Chihiro; Ito, Miwako; Tabiki, Tadashi; Nagasawa, Koichi; Miura, Hideho.
Fusarium head blight (FHB) is one of the most devastating diseases of wheat (Triticum aestivum L.), and the development of cultivars with FHB resistance is the most effective way to control the disease. Yumechikara is a Japanese hard red winter wheat cultivar that shows moderate resistance to FHB with superior bread-making quality. To identify quantitative trait loci (QTLs) for FHB resistance in Yumechikara, we evaluated doubled haploid lines derived from a cross between Yumechikara and a moderate susceptible cultivar, Kitahonami, for FHB resistance in a 5-year field trial, and we analyzed polymorphic molecular markers between the parents. Our analysis of these markers identified two FHB-resistance QTLs, one from Yumechikara and one from Kitahonami. The...
