Skipped Fall Spray? Spring Burndown Is Critical

If fall weed control was skipped, spring burndown just became a whole lot more important. Heading into planting with heavy emerged weed pressure creates a tougher situation for your entire herbicide program. Instead of starting clean, your pre-emergent herbicides are forced to work against established biomass before the crop even emerges.


That matters because dense weed canopy can intercept soil-applied residuals before they ever reach the target zone. When that happens, pre-herbicide efficacy can drop, and surviving weeds gain an early advantage against the crop. The longer those weeds remain in the field, the more they compete for light, moisture, and nutrients right out of the gate.



A clean start still matters. If fields were not treated last fall, now is the time to make spring burndown a priority. Strong planning, timely applications, and the right burndown approach can help reset the field before planting and give pre-emergent products a better chance to do their job.

Do not wait until weeds are too large to control. Talk with your Tri-Ag Sales Agronomist about a burndown program that protects the rest of your seas
