1. Prediction of apparent metabolizable energy and metabolizable energy corrected for nitrogen of corn according to physical classification of the grain
ABSTRACT The objective of this study was to develop an equation to determine the apparent metabolizable energy (AME) and metabolizable energy corrected for nitrogen balance (AMEn) using a physical-based classification of corn. A total of 5,055 samples were taken from bulk cargo trucks, over a five-year period. The parameters studied were the variables relate

2. Effects of the mechanical damage on the water absorption process by corn kernel
The purpose of this study was to investigate and model the water absorption process by corn kernels with different levels of mechanical damage Corn kernels of AG 1510 variety with moisture content of 14.2 (% d.b.) were used. Different mechanical damage levels were indirectly evaluated by electrical conductivity measurements. The absorption process was based

3. 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

4. Fusarium species and fumonisins associated with maize kernels produced in Rio Grande do Sul State for the 2008/09 and 2009/10 growing seasons
Ear rots caused by Fusarium spp. are among the main fungal diseases that contribute to poor quality and the contamination of maize grains with mycotoxins. This study aimed to determine the visual incidence of fungal-damaged kernels (FDKs), the incidence of two main Gibberella (a teleomorph of Fusarium) complexes (G. fujikuroi and G. zeae) associated with mai

5. APLICAÇÃO DE FUNGICIDAS EM DIFERENTES ESTÁDIOS FENOLÓGICOS DA CULTURA DO MILHO (Zea mays) NO CONTROLE DE DOENÇAS
The objective of this study was to evaluate the effects of application timing of fungicides epoxiconazole + pyraclostrobin and azoxystrobin + cyproconazole in corn in the control of Phaeosphaeria leaf spot (Phaeosphaeria maydis), rust (Puccinia sorghi), Cercospora leaf spot (Cercospora zea-maydis), stain Diplodia (Diplodia macrospora) and stem rot. Three exp

6. Influência de fungicida e adubação foliar em características agronômicas e sanitárias da cultura do milho / Influence of fungicide and foliar fertilization on the maizes health and agronomic characteristics
O que define o potencial máximo de produção de uma cultura é o conjunto de fatores relacionados ao histórico da área; ao material genético; às práticas de cultivo; condições climáticas; etc. Dentre estas práticas destacam-se a disponibilidade de nutrientes e a utilização de químicos na proteção contra patógenos. Sendo assim, o objetivo des

7. Fumonisins in corn: correlation with Fusarium sp. count, damaged kernels, protein and lipid content
A contaminação natural por fungos e fumonisinas foi avaliada em 109 amostras de milho recém-colhido do Estado do Paraná e correlacionada com grãos ardidos (%). Além disso, grãos sadios e ardidos de 24 amostras de milho foram selecionados a fim de comparar o perfil da microbiota fúngica e níveis de fumonisinas. A correlação entre os teores de prote

8. Factors Influencing Aflatoxin Accumulation in Peanut Kernels and the Associated Mycoflora1
Accumulation of aflatoxin in Spanish peanut kernel samples from different geographical areas in Texas during 1966, as detected by the thin-layer chromatographic method, was relatively low. Analysis of samples obtained from growers using artificial drying equipment (forced air and supplemental heat), when windrow conditions were unfavorable for rapid drying,

9. Mycotoxins and Fusarium spp. associated with infected ears of corn in Minnesota.
Five Fusarium species were isolated from the grain of dent corn (Zea mays) selected from 20 of 32 damaged fields in 10 counties in Minnesota on the basis of hyphal growth visible on kernels in the field. Three mycotoxins were identified in the infected ears: zearalenone, deoxynivalenol, and 15-acetyl-deoxynivalenol. This is the first report of the presence o

10. Effects of soil moisture and temperature on preharvest invasion of peanuts by the Aspergillus flavus group and subsequent aflatoxin development.
Four soil temperature and moisture treatment regimens were imposed on Florunner peanuts 94 days after planting in experimental plots in 1980. At harvest (145 days after planting), the incidence of the Aspergillus flavus group and the aflatoxin concentration were greatest in damaged kernels. Extensive colonization of sound mature kernels (SMK) by the A. flavu

11. Toxigenic Aspergillus and Penicillium Isolates from Weevil-Damaged Chestnuts
Aspergillus and Penicillium were among the most common genera of fungi isolated on malt-salt agar from weevil-damaged Chinese chestnut kernels (16.8 and 40.7% occurrence, respectively). Chloroform extracts of 21 of 50 Aspergillus isolates and 18 of 50 representative Penicillium isolates, grown for 4 weeks at 21.1 C on artificial medium, were toxic to day-old

12. Emetic and refusal activity of deoxynivalenol to swine.
The minimum emetic dose of deoxynivalenol to swine weighing 9 to 10 kg was 0.05 mg/kg of body weight intraperitoneally and 0.1 to 0.2 mg/kg orally. There was no emesis by undosed pigs consuming vomitus from pigs orally dosed with deoxynivalenol or penned with such pigs without access to vomitus. Analysis by gas-liquid chromatography of a sample of Gibberella
