Editing Western corn rootworm (section)

=== Early planting ===
Early planted fields that have completed pollen shed are less attractive and therefore have less egg laying activity. Early fields have relatively larger root systems when rootworm feeding starts. This makes them somewhat more tolerant. Practices that promote strong root systems and a generally vigorous crop make corn more tolerant to rootworm feeding and damage.<ref name=peairs>Peairs, F.
