چکیده مقاله:
The effect of different compost-soil ratios on the incidence of Pythium aphanidermatum causing tomato damping off was tested in a greenhouse experiment. The inoculum density of 5% was determined to be suitable for inoculation in compost experiments based on investigations of disease incidence with 5, 10 and 20% inoculum densities. To evaluate the effect of compost on incidence of tomato damping off, tomato seeds were sown in compost/soil mixtures at 10, 30 and 50% V:V containing 5% of P. aphanidermatum inoculum. The number of dead tomato seedlings was recorded in two-day intervals and disease incidence was calculated. Results showed that compost/soil mixtures at 30 and 50% ratios significantly suppressed Pythium damping off in tomato seedlings, while 10% compost/soil mixture had no significant effect on disease suppression. This suppression was biologically based since heat-sterilized compost offered little protection from the pathogen. There are antagonistic microorganisms in the composts which are potential biocontrol agents and can be used in bio-pesticides

Combining effects of soil solarization and grafting on plant yield and soil-borne pathogens in cucumber
Combining effects of soil solarization and grafting on soilborne pathogens, plant height and yield in cucumber were compared in a greenhouse of Bati Akdeniz Agricultural Research Institute located in Antalya in 2008 fall season. The experiment was set in split plot design containing; 1, 2, 4 and 5 months soil solarization (MSS), and non-solarized control plots (NSC) on which grafted Maximus F1+...
متن کاملArbuscular mycorrhizal fungal spores host bacteria that affect nutrient biodynamics and biocontrol of soil-borne plant pathogens
The aim of this research was to isolate and characterize bacteria from spores of arbuscular mycorrhizal fungi (AMF). We designated these bacteria 'probable endobacteria' (PE). Three bacterial strains were isolated from approximately 500 spores of Gigaspora margarita (Becker and Hall) using a hypodermic needle (diameter, 200 μm). The bacteria were identified by morphological methods and on the b...
متن کاملVirulence of soil-borne pathogens and invasion by Prunus serotina.
*Globally, exotic invaders threaten biodiversity and ecosystem function. Studies often report that invading plants are less affected by enemies in their invaded vs home ranges, but few studies have investigated the underlying mechanisms. *Here, we investigated the variation in prevalence, species composition and virulence of soil-borne Pythium pathogens associated with the tree Prunus serotina ...
متن کاملBiocontrol and Rapid Detection of Food-Borne Pathogens Using Bacteriophages and Endolysins
Bacteriophages have been suggested as natural food preservatives as well as rapid detection materials for food-borne pathogens in various foods. Since Listeria monocytogenes-targeting phage cocktail (ListShield) was approved for applications in foods, numerous phages have been screened and experimentally characterized for phage applications in foods. A single phage and phage cocktail treatments...
متن کاملEvaluation of Methyl Bromide Alternatives Efficacy against Soil-Borne Pathogens, Nematodes and Soil Microbial Community
Methyl bromide (MB) and other alternatives were evaluated for suppression of Fusarium spp., Phytophthora spp., and Meloidogyne spp. and their influence on soil microbial communities. Both Fusarium spp. and Phytophthora spp. were significantly reduced by the MB (30.74 mg kg-1), methyl iodide (MI: 45.58 mg kg-1), metham sodium (MS: 53.92 mg kg-1) treatments. MS exhibited comparable effectiveness ...
