A total of ten research trials were conducted by BASF Market Development representatives in 1987 across the southern states to evaluate DASHM (BCH-815) versus crop oil concentrate as an additive to sethoxycim for control of rhizome johnsongrass. All treatments were applied utilizing a spray volume of ten gallons per acre.

Five tests were conducted in which rhizome johnsongrass was sprayed with single applications of sethoxydim plus the additives under evaluation. The treatment which gave the most consistent commercial control was sethoxydim at .2 pound er acre plus 1 quart of Dash.

Five field studies were applied as split applications. Sequential applications consisted of .2 pound per acre followed by .2 pound per acre or .1 pound per acre followed by .2 pound per acre. Once again, Dash provided the most consistent control of rhizome johnsongrass regardless of the rate of sethoxycim applied

While moderate improvements in the average control of rhizome johnsongrass across all tests were observed the major observed benefit the use of DASH as an additive to sethoxydim was a reduction in the variability of control.
