Soil-surface applications of isopropyl N-(3-chlorophenyl)carbamate (CIPC), 2-chloroallyl diethyldithiocarbamate (CDEC), ethyl N,N-di-n-propylthiolcarbamate (EPTC), sodium 2,4-dichlorophenoxyethyl sulfate (sesone), and N-1-naphthylphthalamic acid (NPA) were made on a Willacy fine sandy loam just before and after a 24-to-32 mph windstorm, which moved significant amounts of treated soil. All treatments were overhead-irrigated after the storm. All herbicides performed less efficiently after the wind. CIPC was found below the surface of soil only when applications were undisturbed by the wind.

Internal dormancy was shown to occur in western ironweed (Vernonia baldwinni Torr.) and leafy spurge (Euphorbia esula L.) in late summer and fall. Time required for emergence and extent of growth were important indicators of dormancy. Dormancy is apparently broken naturally in the field by low soil temperatures.

In a closed system the vapors from the potassium salt of 4-amino-3,5,6-trichloropicolinic acid caused severe damage and death of Pinto beans. Vapors from the potassium salt of 4-amino-3,5,6-trichloropicolinic acid caused more injury to Pinto beans than vapors from the same application rates of the propylene glycol butyl ether esters of 2,4-dichlorophenoxyacetic acid or the dimethylamine salt of 2-methoxy-3,6-dichlorobenzoic acid.
