Biological control of seedling blight of winter wheat caused by Fusarium culmorum and microdochium nivale
The nature of microbial antagonism towards Fusarium culmorum and Microdochium nivale, the primary pathogens implicated in Fusarium seedling blight of wheat, was assessed in laboratory, controlled environment chamber and semi-field experiments. Dual culture experiments, using five different agar …

Der Einfluss unterschiedlich aggressiver Fusarium culmorum- und Fusarium graminearum-Isolate auf die Schadbildausprägung bei Winterweizen sowie die Möglichkeit der Befallskontrolle mit Mykorrhiza
Der Einfluss unterschiedlich aggressiver Fusarium culmorum- und F. graminearum-Isolate auf die Schadbildausprägung bei Winterweizen sowie die Möglichkeit der Befallskontrolle mit Mykorrhiza Die durch Pilzarten der Gattung Fusarium spp. hervorgerufene partielle Taubährigkeit ist ein ernstes Problem …

The synthesis and fungicidal activity of some novel phosphoramidates
… activity was assessed in vitro against spores of Fusarium culmorum, Fusarium oxysporum, Helminthosporium sativum, Helminthosporium avenge, Septoria nodorum, Ophiobolus graminis, Piricularia oryzoe and Rhizoctania solani and in vivo against Dreschlera teres and Septoria nodorum. These pathogens …

Evaluating populations derived from complex crosses involving both bread wheat and durum wheat parentage for partial resistance to crown rot
Crown rot in durum, caused by Fusarium pseudograminearum and Fusarium culmorum, can reduce yields up to 90% in seasons characterised by limited spring rainfall. To decrease this potential loss, breeding of partially resistant cultivars could complement agronomic approaches. However, the limited …

A comparative study of certain soil-borne cereal pathogens with reference to carbohydrate utilisation and polysaccharide hydrolysis
Cochliobolus sativus, Fusarium culmorum and Gaeumannomyces graminis var tritici isolates produced pectin degrading enzymes, xylanase and carboxymethylcellulase when grown in a salts medium with an appropriate carbon source. There was little difference in the amounts of enzymes produced by the …

Some Studies on the Competitive Colonisation of Cellulosic Substrates by Microorganisms
… down straw in pure culture, C. cinereus and Fusarium culmorum being rather better than the others, and tests indicated that C. cinereus and two other fungi may be able to cause some breakdown of lignin. Most of the more commonly isolated fungi were found to be capable of inhibiting the growth …

The synthesis of fungicidal aminophosphonic acid derivatives
… avenae. Prythium ultlmum. Rhizoctonia solani. Fusarium culmorum. Pyricularia oryzae, Puccinia recondita. Erysiphe zraminis[?] and Septoria nodorum. Results showed that all the phosphonopeptides prepared had moderate to good antifungal activity, with the L-alanine di- and tripeptides of …

Lactic acid bacteria fermentation of wort as a tool to add functionality in malting, brewing and novel beverages
… antifungal compounds, was assessed against Fusarium culmorum, a common fungal spoilage organism in malt. The contribution of phenolic acids to the overall fungal inhibition was found to be limited unless combined with lactate and acetate in a low pH environment, suggesting their contribution …

Molecular techniques for studying <i>Fusarium</i> ear blight of wheat
… assessment to evaluate the severity of <i>Fusarium</i> ear blight (FEB) ofwheat under field and glasshouse conditions. In a field trial, PCR analysis highlighted the problem of diagnosis of FEB of wheat based on visual disease assessment where natural inoculum was present. PCR-based …

Diagnosis and control of foot rot pathogens of wheat
… disease of wheat is caused by the pathogens <i>Fusarium culmorum, F. avenaceum</i> and <i>Microdochium nivale</i>. Symptoms of foot rot are a general browning of the stem base and leaf sheath. There is a discrepancy between the ability of fungicides to control these pathogens <i>in vivo</i> and …

Strategies for Improving the Bacterial Biodegradation of PET
… (Brij-35)), as well as enzymatic treatment using Fusarium culmorum supernatant (FSC) which contains cutinase. Furthermore, the impact of the quorum sensing molecule (QSM) (specifically, 3-oxo-C12-HSL) on PET degradation was investigated in the context of DTAB-treated, FSC-treated, and …

Studies on the chemical control of Fusarium ear blight of winter wheat (<i>Triticum aestivum</i> L.)
… ) were shown to reduce the mycelial growth of <i>Fusarium culmorum, F. avenaceum, F. poae, F. graminearum and Microdochium nivale in vitro</i> by over 90 % compared to the untreated control. In addition, chlorothalonil inhibited spore germination of all species and pyrimethanil reduced the …

Fundamental study of natural and synthetic antimicrobial peptides as novel preservatives against fungal food spoilage
… selected species representing food contaminants, Fusarium culmorum, Penicillium expansum and Aspergillus niger. The peptides inhibit conidial germination, potentially with morphogenic changes and killing activity against F. culmorum hyphae, but suffer salt sensitivity. Mechanistic studies reveal …

Der agglutinierende, antifungale Faktor aus den Knollen von Cyperus esculentus: Optimierung der Reinigung und weitere Untersuchungen zur Hemmung des Wachstums phytopathogener Pilze
… zeigte bei den getesteten Fusariosen Fusarium solani f. pisi, Fusarium moniliformis und Fusarium culmorum eine Hemmwirkung auf das Pilzwachstum, die nicht auf eine Chitinase-Aktivität zurückzuführen ist. Die Hemmwirkung korrelierte mit der Zunahme des Reinheitsgrades des CEF. Die …
