Abstract Take-all and brown foot rot, caused respectively by Gaeumannomyces graminis var. tritici and Fusarium culmorum, are two important components of the foot and root fungal disease complex of winter cereals world-wide. These fungi persist in soil and in crop debris in the same layer of agricultural soil as Collembola, a well represented taxon of soil animals. Previous in vitro tests showed that these fungi grown on agarised medium were readily consumed by springtails. In a simplified… 

Collembola and plant pathogenic , antagonistic and arbuscular mycorrhizal fungi : a review

The review focuses on interactions between plant pathogenic, antagonistic, arbuscular mycorrhizal fungi and Collembola to explore the role of these arthropods in the control of plant diseases caused

Response of plant growth to Collembola, arbuscular mycorrhizal and plant pathogenic fungi interactions.

Under the experimental conditions considered, the presence of Collembola did not decrease the positive effect of G. intraradices on the plant biomass and did not reduce the biocontrol capacity of the arbuscular mycorrhizal fungus.

Effects of springtails community on plant-growth

The objective of this article discussed the role of springtails community on plant growth.

Does substrate water content influence the effect of Collembola-pathogenic fungus interaction on plant health? A mesocosm study

The effect of interaction between the springtail Protaphorura armata (Tullberg) (Collembola Onychiuridae), and the foot and root pathogenic fungus Gaeumannomyces graminis Von Arx et Olivier var.

Mycophagous Soil Fauna for Biological Control of Soilborne Pathogenic Fungi in Greenhouse and Transplant Crops.

The fungal-feeding nematode Aphelenchus avenae can effectively suppress seedling damping-off caused by Pythium ultimum, Rhizoctonia solani, and Phytophthora capsici to a level equivalent to the standard fungicide treatment.

Apple Replant Disease: Causes and Mitigation Strategies.

After replanting apple (Malus domestica Borkh.) on the same site severe growth suppressions, and a decline in yield and fruit quality are observed in all apple producing areas worldwide. The causes

Evidence for a positive influence of fungivorous soil invertebrates on the seed bank persistence of grassland species

It is suggested that by reducing the mortality of seeds due to fungal decay, fungal grazers may influence the dynamics of plant populations and the assembly of plant communities.



Soil-borne plant pathogenic fungi in relation to some collembolan species under laboratory conditions

Interactions between springtails and plant pathogenic fungi (Gaeumannomyces graminis var. tritici, F. culmorum and R. cerealis) living in the same soil layer were investigated under laboratory conditions and conidia of B. sorokiniana were eaten and proved to be a sufficient diet for reproduction of Folsomia candida.

Effects of the springtail Folsomia fimetaria and the nematode Aphelenchus avenae on Rhizoctonia solani stem infection of potato at temperatures of 10 and 15°C.

Effects of mycophagous soil mesofauna on Rhizoctonia solani infection of potato stems were investigated and the best control was obtained when both organisms were present in the soil at high densities.

Functional relationships between Collembola and plant pathogenic fungi of agricultural soils

The interactions between the collembolan Mesaphorura krausbaueri and four soilborne plant pathogenic fungi all living in the same layer of agricultural soil were studied under laboratory conditions to affect the capacity of different fungi to attack the plant and thus modulate the appearance of disease.

Effect of soil pH and amendments with dried fodder rape on mycophagous soil animals and Rhizoctonia stem canker of potato

Rape material, its age and the soil pH significantly affected the suppressive ability of F. fimetaria and A. avenae, and when rape was added to the soil at PH(-KCI) 6.2 its suppressive effect disappeared completely, probably because of the presence of alternative food sources.

Influence of in situ and in vitro pH on suppression of Gaeumannomyces graminis var. tritici by Pseudomonas fluorescens 2-79.

Pseudomonas fluorescens 2-79 (NRRL B-15132) and its rifampicin-resistant derivative 2-79RN 10 are suppressive to take-all of wheat caused by Gaeumannomyces graminis var. tritici. Production of the

Relations trophiques entre la microfaune et la microflore du sol; aspects qualitatifs et quantitatifs

Natural rehydration following desiccation promoted the development of a great number of microbial germs (74430- 103/g in controlled soil sam...

Effect of soil moisture content on the suppression of Rhizoctonia stem canker on potato by the nematode Aphelenchus avenae and the springtail Folsomia fimetaria

The stimulatory effect of dry soil conditions on Rhizoctonia stem canker was counteracted by a greater efficacy of the mycophagous soil fauna under these conditions, and Mild drought stress did not seem to be a limiting factor in the biological control ofstem canker by these two organisms.

Interactions among Gaeumannomyces graminis var. tritici, Trichoderma koningii, and soil bacteria

Interactions among Gaeumannomyces graminis var. tritici, Trichoderma koningii, and soil bacteria were studied in vitro and in soils suppressive and conducive of the saprophytic growth of G. graminis
