Ag Talk: Early Season Weed Control


With glyphosate resistance on the rise, there are several steps producers can take to make sure they get good herbicide activity on soybeans and corn during the early weed control season.

Use multiple modes of action to fight weeds. This usually means using more than one herbicide at a time; some herbicides come premixed for convenience.

Spray weeds when they are less than 4 inches tall. Doing this takes less herbicide, which means less money.

Use residual herbicide tank mix partners. Round up is a common herbicide that does not have residual characteristics.

Monitor the fields on a regular basis to check on what weeds are present and what crop progress is looking like.
