Improvement of soilborne pests control with agronomical practices exploiting the interaction of entomophagous fungi

Abstract

The application of biological control agents (BCAs) is considered as an effective alternative for pest control. However, factors such as the formulation of the product, whose quality can affect the inoculant viability and persistence in soil, the stabilisation of the biocontrol effect under field conditions and the influence of agronomical practices as well as of the environmental conditions (weather and soil) are hampering a wider use of BCAs. After a brief review of these factors, we present some results concerning agronomical and ecological aspects from a case study carried out using different entomopathogenic fungi on organic strawberry plantations, which underline the possibility of improving BCAs efficacy, particularly when integrated into a more general strategy of pest control.
