Midwest US crop health updates

On July 26, early pest alerts spread across the Midwest. In Indiana, corn leaf aphids appeared sooner than usual, prompting some growers to consider aerial insecticide applications. Purdue entomology experts warned that most infestations were small and advised waiting until after pollination and using economic thresholds before treating, to avoid unnecessary chemicals. In the Nebraska Panhandle, western bean cutworm moth flights were high, leading extension specialists to urge intensive scouting of corn and dry beans and to recommend insecticide sprays only when trap counts exceeded established thresholds.

The following day, July 27, growers reported markedly improved crop conditions after recent thunderstorms supplied needed moisture. In north‑central Indiana, about 63 % of corn and soybean fields were rated good‑to‑excellent, with farmers focusing on managing grey leaf‑spot fungus and waterhemp weeds. In Minnesota, USDA data showed 77 % of corn and 78 % of soybeans in good‑to‑excellent condition, attributing the rebound to frequent rains that lifted crops after a dry spell. Disease and insect pressure remained low, and crop development was ahead of schedule.

Together, the snapshots illustrate a shift from early pest vigilance and targeted scouting to a period of favorable weather and overall strong crop health across the Midwest.
