Homonym: Striga (Witch)
Striga, commonly known as witchweed, is a parasitic plant that primarily affects crops like maize and sorghum. It attaches to the roots of host plants, extracting water and nutrients, which can lead to significant yield losses. Striga is particularly problematic in sub-Saharan Africa, where it thrives in warm climates and poor soil conditions.
The life cycle of Striga begins with seeds that can remain dormant in the soil for many years. When conditions are favorable, the seeds germinate and seek out host plants. This parasitic behavior makes Striga a major challenge for farmers, prompting the need for effective management strategies to combat its spread.
