Fields sampled three weeks ago had relatively large numbers of potato leafhoppers, i.e. 20+/20 sweeps. These fields were swathed approximately two weeks ago and averaged 2 potato leafhoppers/20 sweeps, below the treatment threshold. Thus, timely swathing can be very beneficial in managing potato leafhoppers, without use of an insecticide application.
