Natural Control of Weed Invasions in Hyper-Arid Arable Farms: Allelopathic Potential Effect of Conocarpus erectus against Common Weeds and Vegetables

Utilization of plant allelopathic potential to control weed infestations provides an effective, cost-efficient, labor-free, and environmentally acceptable alternative traditional chemical mechanical methods. Conocarpus erectus, known as buttonwood, belongs the Combretaceae family with high contents phytochemicals antioxidant activity. There have been no studies on C. erectus. The present study (1) examined erectus against selected weeds (Chenopodium murale Amaranthus viridis) crops (Solanum lycopersicum Cucumis sativus) via investigating growth inhibition ability its aqueous extract, (2) identified allelochemicals found in this plant. Aqueous extracts were prepared from leaves, roots, seeds by immersing dried powder parts sterile distilled water for 24 h a shaker set 180 rpm. resulting filtrate was considered 100% solution, then dilutions made various concentrations (75%, 50%, 25%). leaves showed highest rate at all Chenopodium viridis grown either Petri dishes or pots. Conversely, studied did not show any toxic effects tomato cucumber plants In dishes, slight reduction observed. HPLC analysis total phenolic methanolic that gallic acid, caffeic ferulic acid (153.963, 69.135, 39.801 ppm, respectively). finding current demonstrated part concentration extraction significant effect phytotoxicity. positive results might be used develop environmentally-friendly herbicides agricultural purposes.
