We are collecting corn tar spot samples and we need your help! Tar spot of corn is a new corn disease first identified in the United States in 2015 in Illinois and Indiana. It has since been confirmed in Iowa, Michigan, Wisconsin, and Florida.

Physoderma brown spot is caused by Physoderma maydis, the only class of fungi that produce zoospores, spores that have a tail (flagellum), and swim free in water.
Please join us in welcoming Dr. Darcy Telenko to our field crops team at Purdue University. Dr. Telenko will have extension and research responsibilities in field crops pathology, and her departmental home will be the department of Botany and Plant Pathology.
Corn diseases have been on my radar these past few weeks as I am just getting my boots on the ground in Indiana. Many aerial fungicide applications are going out around the region, corresponding to crop maturity and the uptick of grey leaf spot.
