Purpose: The appearance western corn rootworm (Diabrotica virgifera LeConte) in Slovenia brings new challenges to machines used for pesticide spraying of corn. The control of western corn rootworm is difficult due to the height of the corn crop in July-August. The current paper presents the exploitation characteristics of mistblower with cannon and field sprayer with high-mounted spraying boom and vertical tube extension with distributing nozzles on pesticide distribution over the corn plant. Design/methodology/approach: Two field experiments with different air adjustments and driving speed (mistblower with cannon) and nozzle flow and driving speed (field sprayer with high-mounted spraying boom) were reserach Findings: The ventilator of the mistblower spread the pesticide over the wider band of the field as the field sprayer, however the pesticide distribution measured as coefficient of variation did not fulfil the legislative requirements. Research limitations/implications: The experiment results presented herein can be applied under similar equipment adjustment, working speed and growing conditions of the corn plant (78.000/ ha and the height of 2.70 m). Practical implications: The field sprayer with high-mounted spraying boom and vertical tube extension was proved as an efficient machine for controlling of western corn rootworm adults in the developed corn growing over 2.70 m. With the presented technical procedure the damage caused by the western corn rootworm can be almost completely prevented. However due to the growing stage of the plant in the time of spreading of the adult, about 6.5 % of the plants are overridden Originality/value: By implementing the findings from our experiments a severe damage in corn yield caused by the western corn rootworm can be reduced significantly. On that way an effective way in production of corn can be contribute to farmers’ economy.
