ABSTRACT:
Herbicidal compositions having systemic herbicidal activity comprise solutions containing one or more systemic herbicides and an amount of an amide and sulfuric acid of the following formula sufficient to accentuate the activity of the systemic herbicide: ##STR1## wherein X is chalcogen, and each of R.sub.1, R.sub.2 and R.sub.3 is independently selected from hydrogen and organic radicals. As used herein, "amide" encompasses all compounds of formula (1) regardless of the chalcogen employed. The molar ratio of amide to sulfuric acid is usually within the range of about 1/4 to less than 2 so that at least some of the sulfuric acid is present as the monoamide-sulfuric acid adduct. The monoamide adduct also acts as a contact herbicide and thereby assists in the immediate control of treated vegetation. Solid compositions comprising combinations of systemic herbicides, sulfuric acid and the useful amides, with and without surfactants, and methods of using the solutions are also disclosed.
