Abstract Plant–parasitic nematodes, specifically cyst nematodes (CNs) and root‐knot (RKNs), pose significant threats to global agriculture, leading substantial crop losses. Both CNs RKNs induce permanent feeding sites in the root of their host plants, which then serve as only source nutrients throughout lifecycle. Plants deploy reactive oxygen species (ROS) a primary defense mechanism against nematode invasion. Notably, both have evolved sophisticated strategies manipulate host's redox environment advantage, with each employing distinct tactics combat ROS. In this review, we focused on role ROS its scavenging network interactions between plants RKNs. Overall, review emphasizes complex interplay plant mechanism, signalling survival tactics, suggesting potential avenues for developing innovative management agriculture.
