Autumn stubble treatment with glyphosate: how to get rid of perennial weeds

In autumn, perennial weeds actively move nutrients from leaves to roots and rhizomes to prepare for winter. A systemic herbicide travels the same way — so an autumn application kills not only the above-ground part but also the root system.

When to spray

• After harvesting the previous crop, let the weeds regrow — spray actively growing rosettes (thistle, bindweed) and couch grass with several leaves.
• Best efficacy is in warm weather, before persistent frosts set in.
• Do not spray weeds damaged by frost or drought or covered in dust.

How to improve glyphosate efficacy

• Use good-quality water — hard water reduces glyphosate activity; water conditioners help.
• Choose the rate according to weed species and stage — as per the product label.
• After spraying, wait 10–14 days before tillage so that the herbicide has time to move into the roots.

What you gain

A field free of perennials in spring means lower spending on spring herbicides, even crop emergence and a better start to the 2027 season.
