Single-flowered mouse-ear

The Single-flowered mouse-ear (Cerastium uniflorum) is a perennial herbaceous plant belonging to the Caryophyllaceae family. It is recognized as a weed species that poses a threat to specific agricultural landscapes, particularly in alpine and sub-alpine regions where it competes with forage and cereal crops.

It is typically found in rocky habitats and alpine meadows, but it frequently invades agricultural pastures and fields in high-altitude farming zones. The plant thrives in cool, moist environments and can easily establish itself in disturbed soils where traditional weeds are managed.

The biology of Cerastium uniflorum is characterized by its hardy, rhizomatous growth habit, which allows it to persist under harsh conditions. It spreads through both seed production and vegetative fragmentation, making it highly resilient to simple mechanical weeding efforts.

The weed's damage potential stems from its ability to form dense mats. These mats outcompete crop seedlings for nutrients and water, inhibit the growth of grasses in pastures, and make mechanical harvest difficult, leading to a direct decrease in the nutritional quality and yield of fodder.

To effectively control this weed, agronomists recommend a combination of strategies:

• Deep tillage and soil aeration to disturb the underground rhizome network.
• Application of systemic herbicides that target perennials, ideally during active vegetative growth.
• Maintaining competitive crop density to prevent the establishment of weed patches.
• Regular monitoring of pasture fields to address small infestations before they spread.
