Our experiments was motivated by more accurate knowing of damages of corn weevil (Tanymecus dilaticollis Gyll.) and the preventive chemical treatments. In the interest of trials we placed from acreage originating corn weevils in isolator. In isolator was 1-2 leafy corn. We ended up the trials three different soil types (sand, transition braun forest soil, clay). Beside the controll setup one dressed (active substance: klotianidin) and one soil disinfected treatments (active substance: teflutrin) were in the case of every soil in the trial. We memorised the perished individual number by 6. day, -by the end of the experiment, percentage of leave surface decreasing, and we determined effectiveness of different pesticides treatments. Our investigations proved the efficiency of seed treatment and the inefficiency of soil disinfection in point of corn weevil damages. On the surface of grain impregnated klotianidin successfully protected juvenile corn from damages of pest due to agent’s absorptive influence. Mayor of the experimental beetles were perished by 6. day (90-95%), and the leave damage was negligable by the end of the experiment too (0-1.35%). Beside of this our results confirmed the decreasing of pesticide effectiveness in the case of compacted soil type.
