Fumigation techniques uphold agricultural productivity, addressing microbial threats, weed presence, pest lifecycle disruption, and shelf-life extension across nurseries, field sites, and granaries. Elements include zineb, ferbam, dazomet, parathion, oxamyl, and dichlobenil. Devices used are dosage meters, expulsion fans, storage wraps, fog dispersers, protective overalls, filtration units, and mobile dispensers. Ecosystem participants include agronomy firms, pesticide control boards, application services, training centers, green innovators, and planning departments. Benefits involve insect exclusion, clean environment, prolonged freshness, and product standardization. Issues include resistance development, user mismanagement, training lapses, and community objections. Developments focus on remote calibration, real-time reporting, smart scheduling, and ecological safety.
