Marcelo Zimmer

Botany and Plant Pathology 

  • Graduate Research Assistant

 Marcelo Zimmer is a M.S. student with Dr. Bill Johnson investigating the efficacy of the new synthetic auxin herbicide halauxifen-methyl on glyphosate resistant horseweed, as well as the weed control spectrum provided by halauxifen-methyl alone and in combination with glyphosate and other synthetic auxin herbicides. The research project also addresses soybean injury from halauxifen-methyl applied at different preplant intervals. The overall objectives of Marcelo’s research is to compare weed control provided by halauxifen-methyl on glyphosate resistant horseweed populations with other herbicides, analyze possible interactions and evidence of residual weed control, and understand the factors that may influence herbicide persistence and injury to soybeans and the type of injury that may develop.
