Fumonisins B1 (FB1) and B2 (FB2), two structurally related mycotoxins with cancer-promoting activity, were recently isolated from corn cultures of Fusarium moniliforme MRC 826. These toxins have been reported to be produced also by isolates of F. proliferatum. Contamination of foods and feeds by F. moniliforme has been associated with human esophageal cancer risk, and FB1 has been shown to be t...

Some oxadiazole derivatives were tested in vitro against Aspergillus parasiticus, Aspergillus flavus, Aspergillus niger, Fusarium solani, Fusarium moniliforme and Stachybotrys chartarum. All compounds showed the highest antifungal activity against S. chartarum. Among these compounds (3a-j), compounds 3a, 3c, 3d, 3e, 3i, 3j exhibited the same level of antifungal activity against all tested mold ...

Freshly harvested high-moisture corn with 29.4% moisture and corn remoistened to 19.6% moisture were inoculated with Aspergillus flavus Link ex Fr. and stored for 4 weeks at about 27 C in air (0.03% CO2, 21% O2, and 78% N2) and three modified atmospheres: (i) 99.7% N2 and 0.3% O2; (ii) 61.7% CO2, 8.7% O2, and 29.6% N2; and (iii) 13.5% CO2, 0.5% O2, and 84.8% N2. Kernel infections by A. flavus, ...

ABSTRACT To investigate the interaction between two major ear-rotting pathogens, maize ears were inoculated with either Fusarium graminearum, F. moniliforme, or an equal mixture of the two. Silk and kernel tissues were periodically harvested throughout the growing season so that a time course of the experimental variables (disease severity, ergosterol content, fungal DNA content, and mycotoxin ...

Fumonisins are mycotoxins produced by Fusarium moniliforme, a common fungal contaminant of corn worldwide, 10 and F. proliferatum, a closely related species.l.Io.'9 The true incidence of F. moniliforme is difficult to determine because F. proliferatum has often been misidentified as F. moniliforme. lO,'3 Certain strains of F. proliferatum also produce moniliformin, but isolates of F. moniliform...

Seeds of rice were treated with Garlic (Allium sativum) clove extract @ 1:0, 1:1, 1:2 dilutions in water, allamanda (Allamanda cathartica) leaf extract @ 1:1, 1:2, 1:3 dilutions in water and Provax-200 @ 0.3% for controlling seed borne fungi, where the seed samples of three rice varieties viz. Katharee, Gutee Aus and Kalijira were collected from farmer’s storages of Bangladesh. The seed germina...

Although fungi cause a recognized problem during storage of recalcitrant seeds of many tropical species, there are no data to date on defence strategies of these seeds against fungal attack. To ascertain whether recalcitrant seeds of Avicennia marina elaborate compounds that might suppress fungal proliferation during hydrated storage, the production and efficacy of beta-1,3-glucanase (EC 3.2.1....

Maize kernel samples were collected in 1996 from smallholder farm storages in the districts of Bomet, Bungoma, Kakamega, Kericho, Kisii, Nandi, Siaya, Trans Nzoia, and Vihiga in the tropical highlands of western Kenya. Two-thirds of the samples were good-quality maize, and one-third were poor-quality maize with a high incidence of visibly diseased kernels. One hundred fifty-three maize samples ...

Samples of seeds and feeds (corn-based and mixed) were collected during surveys in 1991-92 and 1992-93 from two regions of Spain, one in northern Spain where the annual rainfall is over 900 mm, and the other in southeastern Spain where the annual rainfall is about 400 mm. The level of Fusarium contamination was determined in the 657 samples analysed, and results were analysed statistically to a...
