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 کاملIn 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...

At soil temperatures similar to those prevailing when d...
متن کاملeffect of glomus mosseae on cucumber damping off caused by pythium under salinity stress
salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...
