Growers will be eager to seed with the return of warm weather but early weed control also remains a priority — especially for fields that have not received any yet.

If perennials, winter annuals and early emerging weeds — like this stinkweed — are growing, there is no benefit to waiting for later emerging weeds such as lamb’s quarters or redroot pigweed to show up. Weeds present now will have a greater impact on yield than weeds that emerge with or after the crop…

Weeds will be going strong with the sun, especially if they have established roots that reach moisture while newly seeded crop battles dry topsoil conditions. A second pre-seed burnoff may be in order or — if emergence is likely to be slow — the post-seeding pre-emergence window may be a little wider than usual. Either way, early weed control remains…
