Fervenulin is isolated from a nematicidal actinomycete Streptomyces sp. CMU-MH021 with nematicidal activity. It also inhibits egg hatch and J2 mortality of M. incognita (MICs: 30 μg mL and 120 μg mL, respectively).

Calarene, an insecticide derived from the stem of Kadsura heteroclite, is toxic to Meloidogyne incognita, Sitophilus zeamais, and mosquitoes, and can be utilized in the research of plant pests and mosquito control [1] [2].

Roridin A (Roridine A), a compound isolated from Verruca sp., showed nematicidal activity against Meloidogyne incognita.Roridin A is cytotoxic and has immunomodulatory activity.Roridin A has been used in the study of adrenocortical hyperplasia (CAH) and Cushing's disease (CD).

The compound cis-3-Indoleacrylic acid acts as a nematicidal agent and can be isolated from Streptomyces youssoufiensis YMF3.862. It functions as a V-ATPase inhibitor, reducing both the expression and enzymatic activity of V-ATPase. Additionally, cis-3-Indoleacrylic acid causes swelling in Meloidogyne incognita larvae and notable cracking on the cuticle surface [LC50: 16.31 μg mL]. It also inhibits the accumulation of H+ within nematodes.

Isoschaftoside is used as an intercrop due to its allelopathic inhibition of parasitism by Striga hermonthica, an obligate parasitic weed that can devastate the maize crop. Isoschaftoside has anti-tumor, antioxidant, and antimicrobial activities, it also possesses strong nematicidal activity against M. incognita.
