Alpine mouse-ear

Alpine mouse-ear (Cerastium alpinum) is a perennial herbaceous plant belonging to the Caryophyllaceae family. In agronomy, it is categorized as a persistent weed that can thrive in various habitats. While often considered a botanical feature in alpine zones, its presence in agricultural fields necessitates professional management to prevent yield loss.

This weed is typically found in cool, moist, and rocky environments, often encroaching into pastures, meadows, and perennial forage crops. It spreads effectively in soils that are low in nutrients or in areas with poor crop density, where it can quickly establish a foothold and compete for resources with valuable agricultural grasses.

The biology of Cerastium alpinum is marked by its efficient vegetative reproduction through creeping stems and a robust root system. The plant possesses a high capacity for regeneration, even after grazing or mowing. Its seeds can remain viable in the soil for extended periods, contributing to the persistent nature of the infestation across successive seasons.

The primary economic impact of this weed is the reduction of forage quality and quantity. By outcompeting desirable pasture plants for nitrogen and water, the alpine mouse-ear significantly diminishes the nutritional value of hay and forage crops. Its presence often necessitates increased investment in reseeding and fertilizer application to restore the field's productivity.

Control strategies require an integrated approach focusing on both physical and chemical eradication. Mechanical control involves deep tillage and fallowing to disrupt the root systems. Chemical control is usually achieved through the application of systemic herbicides during the plant's active growth phase to ensure translocation into the roots for total eradication.

• Deep cultivation to destroy the root network.
• Targeted herbicide application in early spring or post-harvest.
• Maintaining high crop density to outcompete the weed.
• Monitoring soil health to prevent nutrient-deficient patches.
