Anthemis pseudocotula

Anthemis pseudocotula is an annual herbaceous plant belonging to the Asteraceae family. In agricultural contexts, it is primarily recognized as a segetal weed that frequently invades grain and row crop fields. Understanding its biological cycle is essential for farmers aiming to manage its population and mitigate competition for vital resources.

The native range of this species extends across the Mediterranean basin and Western Asia. It has successfully naturalized in various temperate and subtropical regions, favoring disturbed habitats such as roadsides, field margins, and fallow agricultural land. Its ability to thrive in anthropogenically influenced environments makes it a persistent presence in modern farmlands.

Botanically, the plant is characterized by a branched stem reaching heights of 20 to 50 centimeters and pinnately dissected leaves. The inflorescence consists of typical daisy-like flower heads with white ray florets and yellow disk florets. These features allow the plant to achieve high reproductive success, producing numerous seeds that remain viable in the soil for extended periods.

The environmental requirements of this species include well-drained soils and high solar radiation. It exhibits significant drought tolerance, which grants it a competitive advantage in dry seasons compared to some traditional crops. Effective management involves mechanical hoeing, crop rotation, and the application of integrated pest management strategies to limit its seed bank contribution.

• High seed production capacity.
• Adaptability to neutral or alkaline soil pH.
• High tolerance to solar radiation.
• Competition for moisture and nitrogen.

From an agricultural standpoint, Anthemis pseudocotula is largely viewed as a pest that requires strict management to prevent yield loss. However, it also serves as a host plant for various beneficial insects, contributing to local biodiversity. Balancing its ecological role with the necessity of keeping it out of primary crop stands remains a key objective for sustainable agronomy.
