Linear-leaved mouse-ear

Cerastium lineare, commonly known as linear-leaved mouse-ear, is a perennial herbaceous plant belonging to the Caryophyllaceae family. As a tenacious weed, it is classified within the group of perennial creeping-rooted weeds, known for their aggressive vegetative propagation and ability to colonize agricultural land rapidly.

The plant is predominantly found in open fields, pastures, and croplands across steppe and forest-steppe regions. It poses a significant threat to grain crops, pulses, and forage grasses, often emerging early in the season and quickly forming dense mats that exclude other plants from the soil surface.

The biology of Cerastium lineare is characterized by a strong, persistent root system that stores reserves for regeneration. The plant spreads both through abundant seed production and by rhizome fragments, which can re-root after soil disturbance. This dual reproductive strategy makes it particularly difficult to eliminate through simple mechanical weeding alone.

The economic impact of this weed stems from its competitive nature. It rapidly consumes soil moisture and nitrogen, leading to stunted growth and reduced grain fill in cereal crops. Furthermore, its presence can complicate harvesting processes and contaminate grain yields, thereby decreasing the overall market value of the agricultural product.

Management strategies for Cerastium lineare require a combination of techniques. Essential agronomic practices include deep plowing to expose root systems to desiccation, proper crop rotation, and timely harrowing. Chemical control involves the application of systemic herbicides at the rosette stage or during active growth to ensure the chemical translocates effectively into the roots, preventing regrowth.
