Remember that game of telephone we played as kids? One person says something in to the ear of another and after passing through 10 people or so the starting message, “I like peanut butter” ends up as, “John licks turtles.” Sometimes that can happen with information pertaining to plant diseases. Lately there have been some interesting things said about tar spot on corn in the community. To help clarify, and set the record straight, I published an article on my blog, which can be accessed here.
Tarspot in corn continues to be the hot topic in our field crops this season. I put together a brief update on what we know based on this seasons observations, which can be found by clicking this link.
Physoderma brown spot and node rot is a disease that has been increasing in incidence in the Midwest over the past 5-10 years. We observed this disease frequently during scouting trips throughout the state conducted in late July. Recently, we have been receiving more reports of this disease and questions pertaining to it’s impact on the crop and management. I recently wrote an article on this disease and management recommendations on the Illinois Field Crop Disease Blog. Click HERE to access the article.
