1955 Proc. Brit. Weed Control Conf. 1954 I. 183 The almost complete failure of the more insoluble propham, CIPC and CMU to give control of wild oats may also be connected with the inability of the material to reach the wild oats at the critical time.

1973 F. M. Ashton & A. S. Crafts Mode of Action of Herbicides xiii. 202 Propham is rapidly broken down by microorganisms in the soil; such degradation is promoted by warmth and moisture. For this reason propham has proved most useful in cool season crops.

1992 Weed Res. 32 77 Butralin effects on cell division more closely resemble those reported from the carbamates, propham and chlorpropham.
