Comparative study of the biological activities of the aqueous extracts of two spontaneous plants harvested in the Algerian Sahara [PDF]
arXiv, 2020 The present study investigates the insecticidal and herbicidal effects of leaf extracts from two plants were harvested in the Northern Algerian Sahara. These are Cleome arabica (Capparaceae) and Pergularia tomentosa (Asclepiadaceae). The efficacy of the extracts from the plants was evaluated by the reflux extraction method.
