Chlamydospores are the main propagules used as source of inoculum of Pochonia chlamydosporia in biocontrol experiments of root-knot nematodes. The objective of this study was to evaluate the control of Meloidogyne javanica on tomato plants by the soil application of rice grains colonized by Pochonia chlamydosporia containing just mycelium and conidia, without chlamydospores. The fungus (isolate Pc-10) was grown for 15 days at 26°C on grains of rice, previously sterilized in microwave oven. Two… 

Gams on tHe root-Knot neMatodes [ Meloidogyne incognita ( Kofoid & White ) Chitwood and Meloidogy nemayaguensis rammh & Hirschmann ]

Results demonstrated that mixing P. lilacinum and P. chlamydosporia causes the highest infections on eggs with 85% and 80%, respectively, and caused the highest mortality of juvenile (J2) of M. incognita and M. mayaguensis, compared to the water treated group, at 168 h.

Biocontrol agents in the management of Meloidogyne incognita in tomato

The agent Pochonia chlamydosporia showed greater efficiency in controlling M. incognita on tomato and biological products and the different doses of NemOut™ had no influence on the tomato plant development.

Pochonia chlamydosporia Microbial Products to Manage Plant-Parasitic Nematodes: Case Studies from Cuba, Mexico and Brazil

The research discussed in this chapter concerns the development, innovation and good manufacturing practices of selected native isolates of Pochonia chlamydosporia as potential microbial control agents for the management of root-knot and false root- knot nematodes.



Cover crops and Pochonia chlamydosporia for the control of Meloidogyne javanica

Pochonia chlamydosporia may favour the establishment of the fungus in the soil and enhance the control of the nematode in summer and winter cover plants under glasshouse conditions.

Potencial de Isolados de Fungos Nematófagos no Controle de Meloidogyne javanica

Four species of Arthrobotrys, one of Monacrosporium, and four isolates of Pochonia chlamydosporia were evaluated regarding their potential to control Meloidogyne javanica, under greenhouse conditions.

Isolates of Pochonia chlamydosporia var. chlamydosporia from Mexico as potential biological control agents of Nacobbus aberrans.

Results confirm the potential of this fungus as a biological control agent of N. aberrans and suggest cracked maize is a cheaper substrate than rice and potentially as effective as rice for mass production of the fungus.

Isolation, Selection, and Efficacy of Pochonia chlamydosporia for Control of Rotylenchulus reniformis on Cotton.

The three isolates (37, 26, and 14) that parasitized the most eggs in vitro were also the most effective in suppressing numbers of R. reniformis and in increasing cotton growth in the greenhouse.

Association of Verticillium chlamydosporium and Paecilomyces lilacinus with Root-knot Nematode Infested Soil.

Population densities of Meloidogyne incognita and the nematophagous fungi, Paecilomyces lilacinus and Verticillium chlamydosporium, were determined in 20 northern California tomato fields over two growing seasons and the results suggest V. chlamyrosporium and V. Lilacinus are not effectively suppressing populations of M. incognitas in California Tomato fields.

Quantification in Soil and the Rhizosphere of the Nematophagous Fungus Verticillium chlamydosporium by Competitive PCR and Comparison with Selective Plating

For the first time PCR-based quantification of a fungal biological control agent for nematodes in soil and the rhizosphere is described and evidence for nem atode host specificity is provided that is highly relevant to the biological control efficacy of this fungus.

Colonisation of barley roots by endophytic Fusarium equiseti and Pochonia chlamydosporia: effects on plant growth and disease.

Results of this work suggest that both F. equiseti and P. chlamydosporia are long-term root endophytes that confer beneficial effects to the host plant.

Nematophagous Verticillium spp. in soils infested with Meloidogyne spp. in Cuba: Isolation and screening

The Rothamsted isolate 10 reduced numbers of nematodes to a greater extent than the other isolates, and therefore has the greatest potential as a biological control agent of root-knot nematode populations.
