Summary
Plant Parasitic Nematodes (PPNs) are tiny, pseudocoelomate, unsegmented, bilaterally symmetrical vermiform animals that attack plants. Nematicides are chemically synthesized substances that kill or harm nematodes. Between 1940 and 1950, three chemicals with nematicidal properties were discovered: methyl bromide (bromomethane), D-D mixture, and EDB (1, 2-dibromoethane; as ethylene dibromide) which were fumigants. When fumigant compounds are applied to soil, a gas moves through the open spaces between soil particles or into the water film that surrounds soil particles. Fumigants significantly decrease nematode respiration by oxidizing Fe2+ centers and alkylated proteins in the cytochrome-mediated electron transport chain. Despite the efficacy of fumigants in nematode, their use was lowered d
