Pourriture racinaire du haricot commun causee par Pythium : biologie et methodes de lutte. La pourriture racinaire causee par Pythium constitue une importante contrainte pour la production du haricot commun (Phaseolus vulgaris L.) dans plusieurs regions de l'Afrique centrale et orientale ou la production du haricot est intense dans des conditions de non-respect des schemas de rotation a cause de l’exiguite des terres. Des pertes de rendement allant jusqu'a 70 % au sein des cultivars locaux… 

Myco-Suppression Analysis of Soybean (Glycine max) Damping-Off Caused by Pythium aphanidermatum

P. oligandrum isolates were proven to enhance the germination of Glycine max seedling to 93.3% in damping-off infection using agar pots and promote germination during soil pot assay and increase the shoot, root lengths, and the number of lateral roots.

Characterisation Of Bean Root Rot Pathogens From Soils In Western Kenya And Their Management With Biochar And Vermicompost

In conclusion, soil properties, management practices and elevation affected root rot pathogen populations and should be considered when developing management strategies.

The potential of a Novel Green Manure as a treatment for Replant Disease on Sorbus aucuparia

It was proposed that the use of novel green manures with specific antimicrobial properties as an organic soil addition had the potential to alter the condition of the soil to one that is conducive to tree growth.

Differentiation of Pythium spp. from vegetable crops with molecular markers and sensitivity to azoxystrobin and mefenoxam.

Since the intrinsic activity of azoxystrobin among species was stable and no resistant isolates were found, it may be applied without species differentiation, provided it is used preventatively to also control highly aggressive isolates.

Several Pythium species cause crown and root rot on cannabis (Cannabis sativa L., marijuana) plants grown under commercial greenhouse conditions

Cannabis plants with symptoms of crown rot, root decay, wilting and plant death were sampled during 2018 and 2019 from seven production greenhouses to study the mechanisms behind plant death.

Isolation and identification of pathogenic fungi and oomycetes associated with beans and cowpea root diseases in Oman

The study shows that several fungal species can be found associated with the roots of beans and Vigna unguiculata in Oman and can result in varying disease symptoms.

Common Strategies to Control Pythium Disease

The recent achievements, particularly chemical and physical methods, biocontrol and host plant defense which can be used to control Pythium disease are reviewed.



Races of common bean (Phaseolus vulgaris, Fabaceae)

Multivariate statistical analyses of morphological, agronomic, and molecular data, as well as other available information on Latin American landraces representing various geographical and ecological regions of their primary centers of domestications in the Americas, reveal the existence of two major groups of germplasm: Middle American and Andean South American, which could be further divided into six races.

Biological control of Pythium species

Pseudomonas fluorescens, Streptomyces griseoviridis, Gliocladium virens, Pythium oligandrum and Trichoderma harzianum have been or are about to be used commercially for the control of diseases caused by Pythium.

Pathogenic and molecular characterization of Pythium species inducing root rot symptoms of common bean in Rwanda

High level of resistance to Pythium root rot disease found in diverse varieties of common bean growing in Rwanda constitutes a real advantage to be exploited as source of resistance in breeding programs aiming to increase resistance to the disease in the most popular bean varieties grown in Rwanda.

Accumulation of phenolic compounds in plants and nutrient solution of hydroponically grown peppers inoculated with Pythium aphanidermatum

It is concluded that marked increases in concentrations of phenolics in roots, shoots, and nutrient solutions, and abrupt cessation of growth in hydroponically grown pepper plants inoculated with P. aphanidermatum were associated with the development of root browning.

A new species of Pythium isolated from burgundian vineyards and its antagonism towards Botrytis cinerea, the causative agent of the grey mould disease.

Morphological and molecular characteristics of this isolate justifies its description as a new species: Pythium citrinum, which is very close to P. montanum, a recently described fungus and constitutes a "border species" linking the genera Pythium and Phytophthora.

Inoculation of cucumber roots with zoospores of mycoparasitic and plant pathogenic Pythium species: Differential zoospore accumulation, colonization ability and plant growth response

While Pythium ‘group F’ had a constant, negative influence on root length and plant growth, measured as fresh weight, Pythium aphanidermatum caused generalized necroses of the root system, inhibiting consistently root elongation and plant Growth and finally causing plant death.


Root rot diseases are widespread and often considered a major constraint to bean production, reducing both yield and profitability worldwide. Depending on the pathogen(s) involved, general root rot


Broad spectrum biological control of diseases caused by soilborne plant pathogens such as Pythium, Phytophthora, and Rhizoctonia solani requires the introduction into or presence of edaphic sources

Some Phycomycetes indigenous to soils of old growth forests

By the use of selective media and techniques which favor the isolation of Phycomycetes, 85 soil samples from four old growth forest sites in Kentucky, North Carolina and Tennessee were assayed for
