CONTROL of Meloidogyne incognita and Pratylenchus zeae USING Embelia schimperi EXTRACTS

Abstract

p> Background. Some secondary metabolites found in plants have been used to control pests and pathogens. The plant Embelia schimperi contains complex compounds that can be used to biosynthesize agrochemicals for the control of plant-parasitic nematodes. Objective. This work analysed the phytochemical profile of the E. schimperi plant and assessed the biological potential of its crude extracts. Methodology. The phytochemicals were extracted in three solvents: ethanol, dichloromethane, and hexane, utilising maceration and ultrasonication procedures. Results. These solvents performed well in extracting flavonoids, phenolics, terpenoids, tannins, and saponins, according to the findings. Implication. The root-knot nematode Meloidogyne incognita can be inhibited from hatching, and the lesion nematode Pratylenchus zeae can be killed as a result of these chemicals' bioassay activities. Conclusion. Plant-parasitic nematode may be controlled with crude extracts from this plant, which can be processed into a botanical insecticide.</p … Read more Phytochemical's profile of stem barks extract of E. schimperi.
