In this week’s Boots In The Field Report Ken Ferrie covers some of the questions that came in during the Virtual College. In particular the topic of Tar Spot and what the difference is in pressure and management of “home grown” Tar Spot and “blown in.” The conditions must be right for Tar Spot but when it is, it can cause a huge yield hit. Ken talks through what we have learned so far and how we will continue to learn about this disease in the future.
