The audience for this course is: Plant industry professionals seeking continuing education and extension personnel

Herbicides have been used in agriculture since the 1950s, and quickly resulted in the spread of herbicide-resistant weeds. Originally, naturally-occurring mutations were the source of herbicide resistance in weed populations, but with the advent of advanced crop genetic technologies (such as herbicide resistance), crop-to-weed gene flow has emerged as another source of resistance. The goal of this course is to help students understand how selective pressures are applied to plant populations both in breeding programs and on weed populations growing in fields, to understand outcomes in plant response and competitive ability. Students will learn how to connect applied weed ecology studies with plant breeding, genomics, and biochemistry resources to identify mechanism(s) of herbicide resistance or other adaptive traits. Students will also learn how to assess the environmental impacts of new crop traits in greenhouse, field, and landscape-level environments. Understanding the connection between genotype and phenotype in all plant species within an agroecosystem will improve systems-based thinking and lead to interdisciplinary collaborations within the plant sciences to improve sustainability.
