Leaf spots and root rots are major fungal diseases in Camptotheca acuminata that limit cultivation of the plant for camptothecin (CPT), a promising anticancer and antiviral alkaloid. Bioassays showed that pure CPT and flavonoids (trifolin and hyperoside) isolated from Camptotheca effectively control fungal pathogens in vitro, including Alternaria alternata, Epicoccum nigrum, Pestalotia guepinii...

A compound very similar to the mycotoxin citrinin was observed on thin-layer chromatographic plates during the screening analysis of grain extracts. This compound was produced by 22 of the tested Fusarium avenaceum (Corda ex Fries) Sacc. strains isolated from wheat, triticale, barley, corn, and potatoes. A chemical test confirmed the presence of an unknown compound, which was given the prelimin...

The cereals crops in Belgium are not safe from serious contaminations by mycotoxins. Theyears 1997 and 1998 for example were very favourable to the development of Fusariumhead blight. On that account, the project main objective consists in assessing the risk ofmycotoxins contamination and studying the environmental factors that contribute to increasethe rate of wheat contaminati...

The aim of the study was a laboratory evaluation antifungal effect leaf extracts from yarrow (Achillea millefolium L.), tansy (Tanacetum vulgare sage (Salvia officinalis L.) and wormwood (Artemisia absinthium on fungi genus Fusarium, major cereal pathogens. used 5%, 10%, 20% concentrations plant extracts, evaluating their linear growth Fusarium avenaceum, F. culmorum, graminearum, sporotrichioi...

The supercooling point (SCP) of an insect model, the lady beetle Hippodamia convergens Guérin-Menéville (Coleoptera, Coccinellidae) was markedly elevated by treatment with aqueous suspensions of the filamentous, ice nucleation active (INA) fungi Fusarium avenaceum and slightly elevated by Fusarium acuminatum. Addition of the surfactant Tween 80 to the fungal suspensions further reduced the supe...

Endofitne gljive žive unutar biljaka ne uzrokujući očite simptome bolesti. Korovi koji rastu u blizini poljoprivrednih polja mogu poslužiti kao alternativni domaćin ovih gljiva. Izolirali smo endofitne iz 6 vrsta korova, uobičajenih za istočnu Hrvatsku te bez očitih simptoma bolesti: Abutilon theophrasti, Amaranthus retroflexus, Ambrosia arthemisiifolia, Chenopodium album, Sorghum halepense i X...
