In this week’s CropCast, Seth Naeve and David Nicolai welcomed Dr. Tom Peters and Dr. Debalin Sarangi to discuss “Getting the most out of pre-emergence herbicides.” Dr. Tom Peters is a sugarbeet agronomist specializing in sugarbeet weed control at North Dakota State University and the University of Minnesota, and Dr. Debalin Sarangi is a University of Minnesota Extension Weed Scientist for corn and soybeans.
Both weed scientists reviewed the highlights of the recently published University of Minnesota Crop News article, Getting the most out of pre-emergence herbicides: It starts with your soil in terms of suggestions to aid early season weed control. Their discussed several factors that can affect herbicide performance including soil type, moisture conditions, and soil organic matter content. They emphasized that timing plays a big role in efficacy when it comes to pre-emergence herbicides. These products can be applied before planting, at planting, or right after planting—as long as it’s before the crop emerges. They detailed the effects of soil pH and CEC, herbicide mobility, soil moisture, rainfall and herbicide degradation via specific herbicide types and modes of action which are also listed in the recent crop news article.
