Abstract

When clay granules containing chlorpropham (isopropyl m-chlorocarbanilate) were applied to the surface of moist soil, the herbicide gradually moved to the atmosphere as a vapor and little entered the soil. Chlorpropham killed seedlings of field dodder (Cuascuta campestris Yunck.) and largeseed dodder (C. indecora Choisy) effectively whether it contacted them in the soil or in the air above the soil.
