Residual Herbicides Best Suited to Spring Marestail Management

By Amit Jhala
 
Figure 1. Marestail is best controlled at the rosette stage.
 
Marestail, also known as horseweed or Canada fleabane, is a winter or summer annual weed in Nebraska. Control is most successful in the fall or early spring at the rosette stage. If not controlled then it will compete with corn or soybean throughout the growing season, potentially causing significant yield reduction.
 
Marestail is sensitive to most herbicides labeled for its control early in its growth stage, i.e. the rosette stage. Often growers may rely primarily on post-emergence herbicides applied after the marestail is clearly visible; however, it’s recommended that burndown herbicides (with soil residual activities) be applied in fall/early spring to avoid potential crop-weed competition during summer.

Seed Testing: Regulatory Cost or Competitive Advantage?

Video: Seed Testing: Regulatory Cost or Competitive Advantage?

Most seed companies see testing as a regulatory box to check.

But what if it’s actually one of your strongest competitive advantages?

In this conversation with Amanda Patin, North America Business Development Director for US Crop Science at SGS, we dig into what seed testing really reveals, far beyond germination and a lab report. From seed vigor and mechanical damage to stress performance and pathogen pressure, Patin explains how deeper testing can help companies differentiate their seed, protect value, and drive real return on investment.

If seed testing is something you only think about when you have to, this discussion might change how you see and use it.
