Abstract

When vapor losses of isopropyl N-phenylcarbamate (IPC) and isopropyl N-(3-chlorophenyl)carbamate (CIPC) were studied under controlled laboratory conditions using a direct-trap for vapors, IPC proved more volatile than CIPC. Temperature, air-flow rate, moisture, and cation exchange capacity of soil were important factors influencing volatility. Vapor loss increased with increasing air-flow rate and temperature; losses from moist soil decreased as the percent clay, organic matter, or both, and the exchange capacity increased. Vapor losses were negligible from spray applications on dry soil but were sizable from soils at field capacity which were similar to those from soils saturated with moisture. Vapor losses of IPC from granules were much higher than from a surface spray, and CIPC losses were about the same for the granules as from the spray. Covering the soil-applied herbicide with ⅛ to ¼ in of soil was effective in reducing vapor loss.
