Description
Weeds constitute one of the major biological constraints to rice production in sub-Saharan Africa. This study evaluated the effectiveness of three post-emergence herbicides (Bracer, Bracer Plus and Quinedear) against weedy check in lowland rice fields of Igbaja, Guinea savanna ecology of Nigeria, during 2022 and 2023 wet seasons. Data were collected on weed cover score (WCS), total weed count (TWC), weed dry matter (WDM), weed control efficiency (WCE), and weed flora composition. Results indicated that Quinedear significantly reduced WCS, TWC, and WDM, while improving WCE compared with other treatments. Comparative weed flora analysis revealed that broadleaf weeds such as Boerhavia diffusa and Chromolaena odorata, grasses including Cynodon dactylon, and sedges such as Cyperus rotundus remained dominant across years. The findings demonstrated the potential of integrated herbicide use in suppressing weed proliferation and improving weed control efficiency in Guinea savanna lowland rice systems.
