Synthetic auxin herbicides such as 2, 4-D and dicamba are often utilized to control broadleaf
weeds in preplant burndown applications to soybean. Halauxifen-methyl is a new synthetic …

Together, Conyza bonariensis, C. canadensis and C. sumatrensis show 105 reported cases
of biotypes resistant to herbicides like glyphosate, paraquat, and acetolactate synthase …

Halauxifen-methyl is a new synthetic auxin herbicide for control of broadleaf weeds,
including preplant applications for corn (Zea mays L.) or soybean [Glycine max (L.) Merr.] …

Halauxifen-methyl is an auxin herbicide for broadleaf weed control in preplant applications
to corn and soybean. Our objective for this research was to characterize the phytotoxicity of …

Control of Conyza spp. prior to soybean sowing has faced difficulties because of the
resistance cases in Brazil, hence new herbicides as halauxifen-methyl+ diclosulam are …
