When Should I be Scouting?

June 28, 2013
By: Ellie Murphy, Farm Journal Media Intern

It is important to scout during the entire growing season because different pests will become more prevalent throughout each stage of growth. In Episode 4 of Corn College TV Season 3, Farm Journal’s Associate Field Agronomist Missy Bauer explains how effective scouting can increase yield.

"When we’re scouting our corn throughout the season, one critical time is pollination." Bauer says that at least 1/2" of silk should be present before applying insecticide, so keeping an eye out for silk clippers is key early in the growing season.

As growth progresses, late season pests like spider mites will start to pull nutrients out of the leaves. Bauer says that yield can be affected if this spreads up close to the ear leaf or above.

Watching out for pests is always a good idea. She says, "We actually need to scout corn throughout all of the growing season. I like to keep an eye on it until black layer."
