Other names: Field marigold, chrysanthemum segetum

Family: Asteraceae

Corn marigold is a prominent weed that belongs to the aster family (Asteraceae). It is also known as field marigold or chrysanthemum segetum, identifiable by its vibrant yellow flowers and feathery, fern-like leaves.

The stems of corn marigold are erect. It is commonly found in arable fields, waste areas, roadsides, and disturbed soils. 

Identifying Corn Marigold

Corn marigold resembles other members of the aster family, such as corn chamomile (Anthemis arvensis) and scentless mayweed (Tripleurospermum inodorum). However, several characteristics help differentiate corn marigold from similar-looking plants.

The Challenges of Corn Marigold

Corn marigold can be a problematic weed in agricultural settings, especially in arable fields and crops like cereals and oilseed rape. Like other weeds, particularly broad leaved weeds, it competes with crops for resources such as nutrients, water, and sunlight, leading to reduced yields and crop quality.

One of the challenges in managing corn marigold is its ability to produce a large number of seeds. These seeds can remain viable in the soil for several years, resulting in persistent infestations.
