Water, water, everywhere ...
Everyone talks about the weather, and for good reason. We are mired in a wet cycle; the research center has received nearly 4 inches of rain this week. While moisture is needed for a good crop, (let’s not forget 2012) there can be too much of a good thing. The saturated soil effects on our current crop can range from stunting to death of corn and soybean in severely ponded situations.
When our growing season is wet we often associate that with an increase in plant disease incidence. An issue last experienced in 2011 in our northern Illinois corn crop was Goss’s Bacterial Wilt and Leaf Blight. Commonly referred to as Goss’s wilt, this disease is spread by bacteria that must enter plants through wounds like those caused by hail, heavy rains or high winds. The first case of Goss’s wilt in 2013 was confirmed by the Illinois plant clinic this past week. The corn sample was submitted from Piatt County in east central Illinois, but with this news corn growers in northern Illinois should remain diligent. There are no in-season control options for Goss’s wilt infection. Foliar fungicides are ineffective on the bacterial disease.
Farmers in northern Illinois have a great opportunity to learn about Goss’s wilt and other diseases at the Northern Illinois Agronomy Day on July 10, at the Northern Illinois Agronomy Research Center. Join University of Illinois Extension specialists and researchers as they address issues related to the 2013 growing season. The program begins at 9 a.m. and will finish with a meal provided at noon. It is open to all who wish to attend and there is no registration fee. Weather permitting, presentations will take place outside in the research plots.
