As more farmers hit the fields to bring in this year’s harvest, some are noticing disease take hold late in the game. But in areas like Wisconsin, agronomists say those discoveries likely will not impact yield.
“So we’ve had tar spots start to show up pretty consistently across the footprint. So that showed up late this year. Doesn’t mean that every year it’s going to. It’s not going to be a whole lot of yield impact from this season, but as we move forward in future years, we’re going to need to manage that disease as we look at it. Other than that, a lot of the disease pressure has been pretty mellow, with some Anthracnose starting to show up in spots, which, with poor stalks, is going to continue to add to that challenge,” said Nick Christian.
Nitrogen stress is another concern this fall. Christian urges farmers to get soil testing done before planting next year.
