Corn chamomile

Anthemis arvensis

Introduction: Anthemis arvensis, commonly known as Corn Chamomile or Field Chamomile, is an annual or winter annual flowering plant belonging to the Asteraceae family. Native to Europe, it has become naturalized in various regions across the world. Despite its charming daisy-like flowers, Corn Chamomile is often considered a weed in agricultural fields.

Identification: 1. Morphology:

  • Height: Corn Chamomile typically grows to a height of 20 to 60 centimeters.
  • Leaves: Finely divided, feathery leaves that are aromatic when crushed.
  • Stems: Erect, branched stems covered with fine hairs.

2. Flowers:

  • Inflorescence: Daisy-like flowers with white or yellow rays and a yellow central disk.
  • Blooming Period: Flowers bloom from late spring to early autumn.

3. Habitat:

  • Commonly found in agricultural fields, disturbed areas, roadsides, and other open spaces.
  • Thrives in well-drained soils and is adaptable to varying moisture conditions.

Ecological Roles: 1. Pollinator Attraction:

  • The flowers attract pollinators, including bees and butterflies, contributing to local biodiversity.

2. Soil Stabilization:

  • The root system helps stabilize soil, preventing erosion in disturbed areas.

Invasive Characteristics: 1. Weed in Agriculture:

  • Corn Chamomile is often considered a weed in agricultural settings, where it competes with crops for resources.

2. Rapid Seed Production:

  • The plant produces a large number of seeds, contributing to its ability to spread rapidly.

3. Resistance to Herbicides:

  • Some populations of Corn Chamomile have developed resistance to certain herbicides, posing challenges for effective control.

Control and Management: 1. Cultural Practices:

  • Crop rotation, proper tillage, and maintaining field hygiene can help manage Corn Chamomile in agricultural fields.

2. Herbicide Use:

  • Selective herbicides targeting broadleaf weeds can be used for control in crops.
  • Herbicides should be applied following recommended guidelines to maximize effectiveness.

3. Mechanical Control:

  • Mowing or cultivating fields before the flowering and seed-setting stage can prevent further spread.

4. Integrated Weed Management:

  • Combining cultural practices, herbicide use, and mechanical control as part of an integrated weed management strategy.
