Weed Control in Conventional Corn (Prostko)
several growers are interested in weed control programs for conventional field corn. I suspect that many of you might also be interested in this topic so here are a few thoughts:
1) Conventional field corn hybrids are available from several companies. Here are a few:
Dekalb: DKC59-80, DKC111-30, DKC63-58, DKC66-02, DKC68-37
Dyna-Gro: D57CC51
Pioneer: P1197, P1870, P1608, P17677 all have conventional versions but supply might be limited
2) 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.
3) 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.
