Spectrophotometric determination of the hydrolysis of fluorescein diacetate (FDA) was shown to be a simple, sensitive, and rapid method for determining microbial activity in soil and litter. FDA hydrolysis was studied in soil and straw incubated for up to 3 h. Hydrolysis was found to increase linearly with soil addition. FDA hydrolysis by pure cultures of Fusarium culmorum increased linearly wi...

to identify the fungi associated with foot and root rot of wheat in the khuzestan province, diseased samples were collected at all growth stages in three growing seasons of 2004-2007. pieces of infected parts of the root and foot were surface sterilized and cultured on acidic and non acidic pda media. one hundred and fifteen isolates were obtained and on the basis of macroscopic and microscopic...

Spring barley is grown on about half of the Norwegian cereal area. The rest of the area is equally divided between wheat and oats. Most years the domestic production provides 70%-80% of the domestic market for bread wheat. Barley and oats are mainly grown for animal feed. During the years 2008-2012, severe epidemics of Fusarium head blight have led to increased mycotoxin contamination of cereal...

this study was carried out to identify fusarium species associated with sugar beet root rot and yellows. pathogenicity of fusarium oxysporum, the causal agent of fusariumyellows of sugar beet was also investigated. samples of infected roots were collected from fields in major sugar beet producing areas in khorasan province during 1999-2000. infected roots were washed, surface sterilised and pla...

İkizce buğday çeşidinde üç Pratylenchus thornei popülasyonu (SK11, SK24 ve YLVC24) ile Fusarium culmorum B4 izolatı'nın interaksiyonu eş zamanlı ardışık inokulasyonlarla kontrollü koşullarda araştırılmıştır. Çalışmada nematod popülasyonları için 1000 larva+ergin birey inokulum yoğunluğu kullanılırken, fungus inokulumunda %50 oranında seyreltilmiş kültür filtratı kullanılmış her saksıya 5 mL uyg...

BACKGROUND Tyrophagus putrescentiae (Acari: Astigmata) and Fusarium sp. co-occur in poorly managed grain. In a laboratory experiment, mite grazing resulted in significant reduction of fungal mycelium on cultivation plates. The destruction of mycelium appeared to be a result of an interaction between the mites, fungi and associated bacteria. METHODOLOGY AND PRINCIPAL FINDINGS A laboratory expe...
