Impact of soybean planting date and row width on weed suppression and yield
Agronomy Journal, Volume 117, Issue 5, September/October 2025.Abstract Variable weather patterns and extended growing seasons over the last couple of decades have prompted growers to plant soybean [Glycine max (L.) Merr.] earlier than the historical standard. Field experiments were conducted in Michigan over three site‐years to evaluate soybean planting date, row width, and herbicide program on weed suppression ...

Characterizing the Auxin Herbicide Response in Horseweed ( Erigeron canadensis) [PDF]
, 2018 Auxin herbicides such as 2,4-D and dicamba have been used for over 70 years to control problematic broadleaf weed species. The auxin herbicide mode of action, particularly the precise mechanism in which auxin herbicides initiate the cascade of ...

Control of Horseweed (Conyza canadensis) with Growth Regulator Herbicides
, 2010 The growth regulator herbicides 2,4-D and dicamba are used to control glyphosate-resistant horseweed before crops are planted. With the impending release of 2,4-D–resistant and dicamba-resistant crops, use of these growth regulator herbicides ...

Genetic admixture in species of Conyza (Asteraceae) as revealed by microsatellite markers
Acta Scientiarum. Agronomy, 2017 The distinction among Conyza canadensis, C. bonariensis, and C. sumatrensis is a challenge for weed science. In the current study, primers for microsatellite (SSR) loci were used to investigate the molecular divergence among the three species, the ...
