Abstract
Influence of Pythium oligandrum on Mycelia and Production of Zoo-and Oo-spores of Two Phytopathogenic Pythium spp.
Highlights
As a result of the steady increase in human numbers, those interested in agriculture are looking for ways to increase agricultural crops despite the many challenges
Ability of P. oligandrum to grow and develop on V-8 liquid medium was tested in order to study its effect on mycelium growth, zoospore and oospore production of each of the pathogenic pythia of P. aphanidermatum and P. diclinum
Half strength of filtrate concentration of P. oligandrum (JU0238) reduced radial mycelial growth by 40.1% in the case of P. aphanidermatum (JU0010) and 38.7% in the second isolate of JU0011. It appeared that filtrate of P. oligandrum (JU0238) reduced radial mycelial growth by 22.7% in the case of P. diclinum (JU0020) and 18.6% in the second isolate of JU0021 when using the quarter strength of filtrate concentration
Summary
As a result of the steady increase in human numbers, those interested in agriculture are looking for ways to increase agricultural crops despite the many challenges. Crop diseases have recently spread in a high way This has led to strenuous attempts to increase the productivity of agricultural crops. Which provided methods of chemical control of plant diseases This calls for research on safe ways to control fungal plant diseases, including biological control. Among fungi that causes serious diseases for a large number of agricultural crops are Pythium spp. = pythia) fungi belong to Kingdom Myceteae This kingdom is one of realms of living organisms. Pathogenic fungi of the genus Pythium used in this study caused serious plant diseases resulting in a significant loss in the yield of those plants[2]. Pythium oligandrum Dreschler, used in this research, well known for its role in the biological control to many fungal diseases of crop plants[3,4]
