e0“weed control in glyphosate-resistant soybean”
e1“At 28 DAT in 1999 and 2000, when weeds were no more than 10 cm, pitted morningglory was controlled 91 and 98%, respectively, and hemp sesbania 88 and 100%, respectively, with glyphosate alone at 1,120 g/ha”

Other claims from this paper (17)
- Intervention effect Glyphosate controlled barnyardgrass at least 95%.
- Intervention effect Barnyardgrass control was not antagonized by any of the glyphosate and broadleaf herbicide mixtures.
- Intervention effect Glyphosate controlled wild poinsettia and prickly sida at least 90% at 14 DAT.
- Intervention effect Wild poinsettia was controlled 80% at 28 DAT in the other year with the high rate of glyphosate.
- Intervention effect Prickly sida was controlled 43% at 28 DAT in the other year with the high rate of glyphosate.
- Intervention effect Acifluorfen, fomesafen or lactofen with glyphosate increased wild poinsettia control to 91 to 95%.
- Intervention effect Acifluorfen, fomesafen or lactofen with glyphosate increased prickly sida control to 60 to 83%.
- Intervention effect Acifluorfen, fomesafen or lactofen applied with glyphosate improved pitted morningglory control at 14 DAT in most cases.
- Intervention effect CGA-277476 and chlorimuron with glyphosate increased hemp sesbania control.
- Intervention effect Improvement in weed control with glyphosate and broadleaf herbicide mixtures was noted only in 1998, when pitted morningglory and hemp sesbania were larger.
- Observation Glyphosate alone in 1998 controlled pitted morningglory and hemp sesbania no more than 30%.
- Intervention effect Adding acifluorfen or lactofen to glyphosate kept hemp sesbania control consistently more than 80%.
- Observation Glyphosate alone at 1,120 g/ha controlled pitted morningglory 91% and 98% in 1999 and 2000.
- Intervention effect Acifluorfen, chlorimuron and lactofen caused soybean injury of as much as 14%, 13% and 23%.
- Intervention effect CGA-277476 and fomesafen caused soybean injury of no more than 6%.
- Intervention effect Adding broadleaf herbicides to glyphosate did not improve soybean yield when glyphosate alone gave at least 85% weed control.
- Observation Control remained greater than 90% at 28 DAT in one of the two years.
