Managing Aphids in Corn

Corn aphids have been identified in areas of the Dairyland Seed footprint.

Aphids are a common pest of corn and related grass crops but rarely cause economic levels of damage. The reproductive habit of aphids allows populations to increase very quickly; however, they can also crash quickly, as aphids are highly susceptible to several natural predators, parasitoids, and pathogens. There are no research-based economic thresholds for insecticide treatments, but applications may be justified in drought stressed or late-planted fields with high and increasing aphid populations.
