Evaluation of foliar‐applied post‐emergence corn–soybean herbicides on giant ragweed and waterhemp control in Wisconsin

open access: yesAgrosystems, Geosciences &Environment, Volume 6, Issue 1, March 2023., 2023
Abstract Giant ragweed (Ambrosia trifida L.) and waterhemp (Amaranthus tuberculatus [Moq.] J.D.Sauer) are highly competitive and the most troublesome weeds in corn (Zea mays L.) and soybean (Glycine max Merr.) cropping systems in Wisconsin. Field experiments were conducted to evaluate the efficacy of multiple foliar‐applied POST‐emergence herbicides on

RFLP Analysis of Chlorimuron Ethyl Sensitivity in Soybean [PDF]

open access: yesJournal of Heredity, 1997
Soybean [Glycine max (L.) Merr.] genotypes are known to differ in their chlorimuron ethyl sensitivity (CS). These differences are believed to be controlled by a few major genes. However, the genes controlling CS are probably not the same for all soybean genotypes.
