Agricultural fumigants target storage quality, disease spread, biosecurity, yield enhancement, pest suppression, and growth uniformity across boxes, sacks, tanks, crates, and platforms. Substances comprise anhydrous ammonia, dichloroethane, cyclohexanone, hexafluoride, maleic hydrazide, and oxalyl chloride. Operations involve ventilators, respirators, sprayers, silos, injectors, hoses, trap doors, warning tapes, applicators. Entities engaged are local farms, private agencies, chemical labs, education groups, inspection units, tech collaborators, and supply chains. Benefits include sterilization, hygiene, air purity, loss reduction, seed integrity, and handling efficiency. Risks range from chemical leakage, operator fatigue, unforeseen reactions, and market volatility. Technologies driving growth: sensors, predictive modeling, analytics, green reformulation, and automation.
