Extract

The problem of herbicide volatility has been with us for several years, and promises to remain with us for some time. Mullison, et al. (4) in 1953 pointed out the reasons why physical measurements of herbicide volatility were impractical. Their arguments that the phenoxy herbicides generally have a low order of physical volatility and that analytical methods are insufficiently sensitive to measure the amounts of such herbicides which escape through volatility are still valid.
