In vitro Evaluation of Biocontrol Agents Against Damping Off Disease Caused by Pythium debaryanum on Tomato
Damping-off diseases incited by different species of Pythium are a persistent problem worldwide, often resulting in reduced yields and occasionally resulting in major crop damage. There have been increasing restrictions on the use of chemical fungicides, and the development of disease-suppressive biocontrol agents has become a major goal of horticulture crops. An experiment was conducted with t...
متن کاملAspergillus terreus Inhibits Growth and Induces Morphological Abnormalities in Pythium aphanidermatum and Suppresses Pythium-Induced Damping-Off of Cucumber
The study investigated the efficacy of two isolates of Aspergillus terreus (65P and 9F) on the growth, morphology and pathogenicity of Pythium aphanidermatum on cucumber. In vitro tests showed that the two isolates inhibited the growth of P. aphanidermatum in culture. Investigating P. aphanidermatum hyphae close to the inhibition zone showed that the hyphae showed abnormal growth and loss of in...
متن کاملExploitation of Trichoderma species on the growth of Pythium Aphanidermatum in Chilli
Damping-off of chilli caused by Pythium aphanidermatum is a major nursery disease in vegetables. In vitro experiments evaluated the effect of eight isolates of Trichoderma species (from chilli rhizosphere) were tested against P. aphanidermatum. All the Trichoderma species had varied antagonistic effects against the pathogen. Among them, TVC3 recorded maximum growth inhibition of P. aphanidermat...
متن کاملIn vitro and In vivo antifungal activities of Iranian plant species against Pythium aphanidermatum
Crude aqueous and methanolic extracts of 97 plant species belonging to 35 families collected from the west of Iran were screened for antifungal activity against economically important phytopathogenic fungi, Pythium aphanidermatum. Bioassay of the extracts was conducted by paper disc diffusion method on agar plate cultures with four replications. Seventeen of 97 (17.5%) plant species showed inhi...
متن کاملBiocontrol strategy, Compost, Soil-borne pathogens management
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...
