Survival of Pochonia chlamydosporia on the soil surface after different exposure intervals at ambient conditions.

Background: Exposure of the nematophagous fungus Pochonia chlamydosporia to solar radiation and elevated temperatures before being incorporated into the soil can reduce its survival and efficiency as biocontrol agent.

Aims: A field experiment was carried out to assess the effect of the exposure period on the viability of P. chlamydosporia applied on the soil surface.
