In this episode of Talking Crop, University of Illinois Extension Commercial Agriculture Specialist, Steven Brand, and host, Kathryn Seebruck, discuss tar spot identification, conditions that are favorable to disease development, and best practices for tar spot prevention and control. More information on tar spot conditions: Conditions favorable to tar spot development are milder, wet weather. Temperatures between 63-75F are ideal, and the fungus needs moisture to propagate. Morning dews and rain showers will aid in the spores spreading between leaves and plants. High temperatures, drought conditions, and humidity over 90% will inhibit disease propagation.
