Monitoring of plant lodging and yield response was performed with the aim to quantify the maize plant response to WCR (Western corn worm) larvae root damage. Results of plant lodging ranged from 5.39% to 22.26%. Ploughing down of harvest residues slightly decreased percentage of the plant lodging from 12.92% to 15.24% comparing to the removal of harvest residues. Yield response to CR was followed by 565 kg/ha prior to and 586 kg/ha after the WCR appearance. Yield differences were 2.861 t/ha and 2.840 t/ha, percentage of yield losses was 35.6% and 33.0% in CRO and CR1, respectively.
