Wyatt Petersen

Botany and Plant Pathology 

  • Graduate Research Assistant

Wyatt grew up in central Minnesota and received his Bachelor’s degree in Biology from Brigham Young University in 2017. He is a second year Master’s student working with Dr. Bill Johnson. Wyatt studies various weed control aspects in corn-cover crop systems. These aspects include residual herbicide efficacy in cover crop residues, cover crop termination strategies in corn, and corn yield loss due to cover crop termination strategies. Herbicide resistance has become the most important driver of weed management decisions among growers, which has led to heightened interest in using cover crops for weed suppression. Relatively little is known about cover crops, and even less is known about how conventional weed control methods and cover crops interact. Cover crop acreage has increased substantially in recent years, and understanding how to mesh herbicidal weed management with cover crops to improve weed control and protect corn yield are important for further adoption. This research will help growers make optimal decisions in cover crop termination, weed control, and herbicide resistance management.

Expected graduation: December 2019.
