The nematophagous fungus Pochonia chlamydosporia var. chlamydosporia is one of the most studied biological control agents against plant (semi-) endo-parasitic nematodes of the genera Globodera, Heterodera, Meloidogyne, Nacobbus and, more recently, Rotylenchulus. In this paper we present highlights from more than three decades of worldwide research on this biological control agent. We cover diff...

A novel method was described for promoting conidial production of nematophagous fungus, Pochonia chlamydosporia AS6.8, by hydrogen peroxide (H2O2) treatment and two-stage cultivation. The fungi were first grown on potato dextrose agar plates to encourage vegetative growth, after briefly treating with 90 mM concentrations of H2O2, and then were transferred to water agar (WA) plates for sporulati...

Nematophagous fungi Pochonia chlamydosporia and P. rubescens colonize endophytically barley roots. During nematode infection, serine proteases are secreted. We have investigated whether such proteases are also produced during root colonization. Polyclonal antibodies against serine protease P32 of P. rubescens cross-reacted with a related protease (VCP1) of P. chlamydosporia, but not with barley...

The use of biological control agents could be a non-chemical alternative for management of Meloidogyne spp. [root-knot nematodes (RKN)], the most damaging plant-parasitic nematodes for horticultural crops worldwide. Pochonia chlamydosporia is a fungal parasite of RKN eggs that can colonize endophytically roots of several cultivated plant species, but in field applications the fungus shows a low...

Pochonia chlamydosporia is a worldwide-distributed soil fungus with a great capacity to infect and destroy the eggs and kill females of plant-parasitic nematodes. Additionally, it has the ability to colonize endophytically roots of economically-important crop plants, thereby promoting their growth and eliciting plant defenses. This multitrophic behavior makes P. chlamydosporia a potentially use...

We have investigated the presence of fungal egg-parasites in Spanish soils with plant endoparasitic nematodes. Nine out of 68 samples (13%) yielded fungal parasites. The most common (seven strains) was Pochonia chlamydosporia var. chlamydosporia (= Verticillium chlamydosporium var. chlamydosporium), but Lecanicillium lecanii (= Verticillium lecanii) and Paecilomyces lilacinus were also found. M...

The objective of this study was to use chlamydospores of the fungus Pochonia chlamydosporia (isolates VC1 and VC4) against Toxocara canis eggs in a 15-day in vitro assay. One thousand T. canis eggs were placed in Petri dishes containing 2% water agar medium with different concentrations of chlamydospores (1,000, 10,000 or 100,000) of each fungal isolate of P. chlamydosporia (treated groups) and...

The ovicidal activity (type 3 effect) of fungi Pochonia chlamydosporia (VC1 and VC4 isolated) and Paecilomyces lilacinus (PL1) on Taenia saginata eggs was compared in an experimental trial. T. saginata eggs were fixed onto Petri dishes containing 2% water-agar (2% WA) and fungal isolates, and onto Petri dishes without fungus as control. The ovicidal activity of these fungi was evaluated after b...
