Bacterial Leaf Streak of Corn: A New Corn Disease in South Dakota

Bacterial leaf streak, caused by Xanthomonas vasicola pv. vasculorum (Xvv), is a recently discovered disease of corn in South Dakota. The disease was first identified in Nebraska in 2016 but now has been found in the majority of the Corn Belt states. Under favorable weather conditions bacterial leaf streak can develop to reach yield reducing levels. Like any other bacterial disease, once symptoms develop there is little that can be done to control it in the field. However, it is important to correctly diagnose this as a bacterial disease because it can be confused with gray leaf spot which is a fungal disease.

South Dakota 4-H Robotics - Getting Started

In South Dakota 4-H Robotics is about much more than the competition. It is about the development of youth through experiential learning. During the program youth are introduced to a variety of science, technology, engineering, and math (STEM) concepts, but also develop a variety of life skills including, but not limited to: problem solving, communication, and teamwork.
