Abstract:Distribution of HCN in tobacco warehouse fumigation was studied when the gas was released by different methods. Uniform distribution was obtained in 1 hour when the gas was released throughout the entire warehouse; 4 hours required when it was released along the central aisle.
When a 16-ounce-per-1000-cubic-foot dosage of HCN was used, gas concentration was low throughout the entire fumigation. A booster shot of an additional 16 ounces after 8 hours greatly increased the rate of recovery. After 4 hours, the difference in recovery from 24- and 32-ounce dosages was 2 ounces or less. There was little difference in recovery from 32-ounce dosages either released all at once or half released as a booster' shot.
Dosages of 16 and 24 ounces per 1000 cubic feet gave high mortality of cigarette beetle (Lasioderma serricorne (F.)) larvae to a depth of 3 inches in tobacco. Thirty-two ounce dosages were effective to 5 inches. As shown by weekly trap records, the 32- ounce dosage was more effective than a 24-ounce dosage, and the 24-ounce more effective than a 16-011ounce dosage.
