Chemical control of Didymella bryoniae in cucumbers

Netherlands Journal of Plant Pathology, 1978
The effect of a number of fungicides on mycelial growth ofDidymella bryoniae on agar was tested and compared with the effect on inoculated plants and in commercial crops. Activities in vitro and vivo are not always correlated. Spraying of inoculated young plants is a reliable and quick method for testing fungicides againstD. bryoniae.

Experimental factors favouring infection of attached cucumber leaves by Didymella bryoniae

Transactions of the British Mycological Society, 1978
Didymella bryoniae (Auersw.) Rehm causes black rot infection in attached cucumber leaves. Environmental factors influencing infection were examined in the laboratory. Hydathode regions close to main veins were the most susceptible areas of the intact leaf to fungal infection. Mechanical injury increased susceptibility to conidial infection.

Analysis of the hyphal wall of Didymella bryoniae: composition and sensitivity to hydrolytic enzymes

Mycological Research, 1990
Hyphal walls of Didymella bryoniae are shown to consist of glucose (14%), mannose (10·1%), galactose (2·5%), N-acetyl glucosamine (33·7%), protein (14·0%), uronic acid (8·1%) and phosphate (2·0%). (1−> 3)-β-glucan and chitin are present in the wall, but (1−> 3)-α-glucan is not.

[Transformation of Didymella bryoniae mediated by Agrobacterium tumefaciens].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2011
Gummy stem blight, a plant disease caused by Didymella bryoniae, is one of the major diseases in melon. The disease can seriously reduce melon yield and quality. However, little information is available on the genetics and functional genomics of the fungal pathogen.

Aspetti fisiopatologici dell'interazione Didymella bryoniae - melone

1999
Didymella bryonia è I'agente causale del "cancro gommoso", una delle principali fitopatie fuingine del melone e di altre cucurbitacee. La sintomatologia è rappresentata dalla presenza di aree necrotiche marcescenti su foglie, steli e frutti e da abbondanti essudati gommosi.

Attack of Didymella bryoniae on Roots of Cucumber

Journal of Phytopathology, 1987
Abstract Didymella bryoniae is very common in cucumber crops grown in Danish glasshouses and is able to attack all aerial parts of the plant. In October 1984 an attack of D. bryoniae on cucumber roots was observed for the first time. Some of the roots were dark because of pseudothecia containing asci.

Comparison of inoculation methods with Didymella bryoniae on Cucumis sativus

Euphytica, 1981
A good correlation between foliage attack of young and mature plants was observed. No evidence could be found that plants showing some resistance to plant infection produce fruits less susceptible to internal fruit rot. The extent of external fruit rot depended on the extent of wounding and on the thickness of the peel.
