If that same 100t silo is only half full of grain, it still requires 200 phosphine tablets for effective fumigation. Never use phosphine while grain is in transit. Residues of phosphine generally increased with dosage and the number of fumigations; however, the highest residue (11.3 ppb) occurred after 3 fumigations at the highest dosage (1.12 mg/liter). Since phosphine gas diffuses to an equal concentration within the structure containing it, volume (cubic footage, Figure 1) is usually a better way to calculate dosage than the number of bushels. Phosphine fumigant is very toxic to humans, animals and pests, hence the exposure of human to phosphine is restricted.
