Acuron offers broad-spectrum control of more than 70 weeds in corn, including giant ragweed, common ragweed, Palmer amaranth, waterhemp, marestail
, kochia, cocklebur, morningglory and Russian thistle.
Control of glyphosate-resistant marestail
and hairy fleabane in orchards and vineyards.
Conservation practices were colonized at differing levels with local, nonplanted vegetation that mostly included marestail
(Conyza canadensis), redvine (Brunnichia cirrhosa), vetch (Vida sp.), goldenrod (Solidago spp.), giant ragweed (Ambrosia trifida), curly dock (Rumex crispus), dewberry (Rubus trivialis), blackberry (Rubus oklahomus), johnsongrass (Sorghum hakpense), erect poison ivy (Toxicodendron radicans), broomsedge (Andropogon virginicus), honey locust (Gleditsia triacanthos), American elm (Ulmus americana), and sugarberry (Celtis laevigata).
They have also begun studies on a strain of Xanthomonas bacteria found to infect the leaves of common cocklebur, marestail
(or horseweed), and other herbicide-resistant threats to southern crops and potential targets for bioherbicide use.--By Jan Suszkiw, ARS.
Overall, weeding is a fine balance between spraying perennials (such as marestail
, rosebay willowherb, docks), hoeing annual weeds and flame-throwing the gravel.

triggered, in 2004, "an estimated 10 percent increase in the average pounds of herbicides applied per acre").
