A method for controlling the number and harmfulness of phytophage populations at rape fields includes carrying out visual and pheromone monitoring of a species composition in the course of a vegetation period, establishing threshold levels of the number of dominating pests, carrying out double settling of a mixture of two species of Trichogramma, in particular Trichogramma pintoi and Т. evanescens, single settling of Habrobracon, in particular Habrobracon hebetor Say., treating plants with the biopreparation Phytoverm. |
