Sonchus oleraceus (weed) L. - (annual sowthistle)
This plant is native to Europe and western parts of Asia, but now has a world-wide distribution. It is a common weed in many crops, including cereals, vegetables, cotton and grapevine. High densities can result in yield losses of 50% or more (e.g. see Manalil et al., 2020).
Common sowthistle is an annual plant and can grow to a height of up to 1 m. The stems are hollow and the leaves are normally lobed. The flowers are yellow or orange and each plant produces several thousand seeds per year which are attached to a pappus and disperse mainly by wind.
