Composts are known for their suppressive properties toward many different seed- and root-infecting pathogens and diseases. Although disease and pathogen suppression induced by composts is believed to be mediated by microbial activities, the nature of the microbial species and processes responsible for suppressiveness remain unknown. We demonstrated previously that seed-colonizing microbial cons...

this study was carried out to evaluate the antifungal efficacy of garlic essential oil (allium sativum l.) and two fungicides including metalaxyl- mancozeb and mancozeb against phytophthora melonis, p. drechsleri and p. capsici the causal agent of damping- off on pepper, melon and cucumber, in vitro and greenhouse conditions. fungal radial growth for each concentration of garlic oil on phytopht...

The study was carried out to evaluate the effect of Trichoderma longibrachiatum against damping-off pathogens on four commercial cultivars cucumber in vitro. Various sites Najaf province including (Abasia, Quzwenia, Haydaria, Manathera and Meshkab) were surveyed detect spread studied disease. Pathogenic fungi isolated from roots stem parts infected plants that collected then diagnosed morpholog...

for determination the host range of fusarium stem and root rot of green-house cucumber (cucumis sativus) that caused by fusarium oxysporum f. sp. radicis-cucumerinum, after isolation, identification and study of pathogenisity, 16 species of several plant families were artificially inoculated with this pathogen by sand and corn meal contaminated with pathogen, two varieties of cucumis melo, of c...

Soil degradation has been a very serious problem for sustainable production, especially by a re-cropping of greenhouse-cultivated cucumber (Cucumis statirus L.). The aim of this research was to expound the actuality for soil degradation, at the same time, put forward some suggestion for preventing from soil degradation and maintain sustainable production in greenhouse basic on the two experimen...

BACKGROUND Autotoxicity of cucumber root exudates or decaying residues may be the cause of the soil sickness of cucumber. However, how autotoxins affect soil microbial communities is not yet fully understood. METHODOLOGY/PRINCIPAL FINDINGS The aims of this study were to study the effects of an artificially applied autotoxin of cucumber, p-coumaric acid, on cucumber seedling growth, rhizospher...

due to the high antagonistic activity of bacterium, bacillus subtilis (ehrenberg) cohn, three isolates (b.s.ham, 204 and 202) were selected and their efficacy were studied in control of sugar beetdamping–off caused by rhizoctonia solani , in  in vitro and in vivo conditions.  in dual culture on pda, all isolates of b.subtilis inhibited mycelial growth of r.solani.  significantly, volatile metab...
