Identifying Groundsel
Groundsel
The leaves of groundsel are alternate, lobed, and somewhat fleshy. The lobes give the leaves a somewhat tooth-like appearance. The leaves are bright green in color.
The flowers of groundsel are small and yellow, arranged in compact clusters at the ends of the stems. The flower clusters resemble miniature daisies. The flowers bloom throughout the year, although they are most prominent in spring and summer.
The Challenges of Groundsel
Aside from the competition of resources in arable crops, groundsel has the ability to produce numerous seeds that can remain viable in the soil for several years. These seeds can germinate and establish new infestations, leading to ongoing weed management efforts.
Managing Groundsel
Proper timing of herbicide applications is crucial for effective control.
When using herbicides, selective options that target broadleaf weeds while sparing desired plants should be chosen always using best practice of multiple modes of action to prevent resistance. It is important to follow the instructions and safety guidelines provided by the herbicide manufacturer when applying these products.
