The past few days I had a question or two about conventional corn. According to Dr Prostko, there are a few conventional field corn hybrids available from several companies.
Dekalb: DKC59-80, DKC111-30, DKC63-58, DKC66-02, DKC68-37

Pioneer: P1197, P1870, P1608, P17677 all have conventional versions but supply might be limited

Dr Prostko suggests a few things about weed control.
Here is a slide from my 2025 county presentation about weed control in conventional field corn. Growers need to double-check labels since some herbicide tank-mixes are prohibited (i.e. Callisto and Dual Magnum or Outlook). Also, growers need to confirm the tolerance of any field corn hybrid to the WSSA/HRAC Group 2, Group 15, and Group 27 herbicides. If Counter is used in-furrow for soil insects/nematodes, Callisto, Revulin Q, and Steadfast Q cannot be applied POST.

Here are some field pictures of these herbicide programs from my 2023 and 2024 research plots. This research was partially supported by the Georgia Corn Commission.
