e6“For three of the five herbicides evaluated on rhizome johnsongrass, paraffinic oil at a spray volume of 9.4 L/ha was the only diluent that resulted in season-long control”
e7“Rhizome johnsongrass control with this diluent also resulted in significantly higher soybean yields than all other diluent-spray volume treatments”

Other claims from this paper (5)
- Intervention effect Paraffinic oil as diluent at 9.4 L/ha needed one-half the herbicide rate of water plus POC or SOC at 187 L/ha to control seedling johnsongrass.
- Intervention effect Herbicide rates were reduced with once-refined soybean oil as diluent at 9.4 L/ha, except for the ethyl ester of quizalofop.
- Intervention effect Sethoxydim at 224 g ai/ha was equally effective on seedling johnsongrass in soybeans with air-assist, CDA or conventional sprayers, regardless of diluent.
- Intervention effect Conventional application was effective against johnsongrass only when 1.25% SOC or POC was part of the diluent.
- Intervention effect For three of five herbicides on rhizome johnsongrass, paraffinic oil at 9.4 L/ha was the only diluent giving season-long control.
