摘要

A method for biological control of pest organisms in a agricultural, horticultural or forestry plant population by application of beneficial organisms, comprising the following steps: generating a supply of beneficial organisms in the form of hatchable eggs of parasitic wasps; Producing a supply of a relief-like, with trough-like depressions executed surface structure having carrier substrate particles of corncob granules with a mean grain size of between 1 mm and 15 mm; Generating a spreading formulation by applying the hatchable eggs of parasitic wasps to the surface of the corncob pellets in its trough-like depressions; Application of the application formulation in a agricultural, horticultural or forestry plant stock.
