Abstract

Vapor losses of 2,6-dichlorobenzonitrile (dichlobenil) were studied under controlled laboratory conditions by trapping vapors directly in a magnesia silica absorbant. Vapor losses increased with increasing temperature. Herbicide loss from a spray formulation in 3 hr amounted to 10% at 30 C and 18% at 40 C. Volatility increased as the soil moisture level increased from air dryness to field capacity. However, as the moisture level was increased to saturation, vapor losses remained similar to losses at field capacity. Volatility from a granular formulation was reduced when compared to the spray application. Volatility decreased as the cation exchange capacity of the soils increased.
