Cover Story: A nematicidal actinomycete strain, WH06, was isolated from soil samples and identified using 16S rRNA as Micromonospora sp. It was cultured on 10 media (1#–10#) to observe its growth status. It has no aerial mycelium, and its colonies had an orange–red color when cultured for 10 days. Through medium screening, large fermentation, the collection of the ethyl acetate phase, and the purification of the secondary metabolites, 10 compounds were identified. Among them, N-acetyltyramine, benzenepropanoic acid, 3-hydroxybenzoic acid, and 4-hydroxybenzoic acid exhibited nematicidal activity against Meloidogyne incognita. Meanwhile, benzenepropanoic acid showed an inhibitory effect on M. incognita egg hatching. View this paper
