Fumigants in agriculture function to maintain cleanliness, yield health, and disease mitigation across crops, granaries, barns, bagging areas, cargo bays, and farm units. Active agents include bromopropane, acrylamide, cyanamide, nitrosamines, fluorosilicate, phosgene, and ethyl acrylate. Tools employed are atomizers, coolers, respirators, tanks, controllers, monitors, automation kits, cylinders, and encasements. Market players include commodity boards, government bodies, scientists, machinery suppliers, educators, field officers, software firms, and certification agencies. Benefits encompass long-term storage, contamination control, longevity, postharvest security, infestation reduction, and freshness. Constraints include complex logistics, equipment needs, safety training, community resistance, and geographic variability. Advancements involve smart devices, modeling software, and GPS tracking.
