A method for regulating the size of an entomocomplex at rape fields includes monitoring of agrocenoses and directed settling of Trichogramma. At the beginning of the vegetation period double overall settling of Trichogramma (Trichogramma pintoi) is carried out onto fields and along the periphery of the fields. In addition, along the perimeter of the fields a catching crop, in particular the garden yellowrocket (Barbarea vulgaris), is sown as a continuous band. After mass settling of the garden yellowrocket with pests treatment thereof is carried with the simultaneous edge treatment of the fields along the perimeter with the biopreparation Phytoverm. |
