Abstract
This study investigates the potential suppression effects of aqueous extracts derived from selected
plants on the growth of carrot weed (Parthenium hysterophorus L.) in Arusha, Tanzania. The
research aimed to explore natural and sustainable methods for managing the proliferation of this
invasive weed species. Through a series of laboratory experiments, aqueous extracts were
prepared from specific plants namely amaranth (Amaranthus spinous L.), neem (Azadiratchta
indica L.) wheat millet (Sorghum bicolor), and marigold flower (Tagetes erictus L.). The extracts
were tested against carrot weed in the laboratory and pot experiment for their effectiveness in
inhibiting the germination and growth of carrot weed seeds under controlled conditions. Lea
