Macey Thomann is crop scouting this summer for her internship in Ainsworth and grew up in Riverside on a family farm that raises cattle and row crops. She is the daughter of Ken and Becky Thomann and has a huge passion for agriculture. She currently attends Iowa State University and is majoring in Agricultural Business with a minor in Agronomy. Macey is currently scouting close to 6,000 acres this summer and has been working closely with the producers telling them what all she has been seeing in their fields and giving suggestions on what they can do to better their crops and operations. Recently Macey has been gathering tissue smaples to be sent in to be tested to help the producers scientifically break down the condition of their crops and identify deficiencies and any other issues. After school Macey's goal is to work with a business that she can work closley wit farmers and other compainies to help keep the ag industry strong! Thank you for your continued hard work and dedication Macey!

Fungicides: With all the wet weather we have been receiving here in southeast Iowa lately it looks like fungicides wouldn't be a bad idea to use this year. We are too late in the growing season and replanitng isn't an option anymore so fungicide is the best thing you can do at this point to help insure you are protected from diseases, stress, or physical damage the crop has already received. Ainsworth's summer crop scouting intern Macey Thomann has been in the fields collecting numerous tissue samples and has been mostly seeing three different reoccurring diseases so far this season; Physoderma Brown Spot, Gray Leaf Spot, and Eye Spot.
Physoderma Brown Spot: Caused by chytridiomycete called Physoderma maydis, a class of fungi that produce spores that can survive in the soil and crop debris for 2-7 years. These fungi spores are dispersed by wind or are splashed into the whorls of corn plants. When the spores get into the whorls and they fill with water for an long period of time the spores germinate and infect the tissue of the developing plant. When scouting for Physoderma Brown Spot look for lots of really small round or oval spots that are about 1/4 inch in diameter that are yellowish to brown in color and will usually occur in broad bands across the leaves.
Gray Leaf Spot: Caused by a fungus called Cercospora zeae-maydis. This disease is pretty common and occurs almost every growing season. The fungus survives in corn residue and therefore is more common and severe in corn on corn rotations and is dispersed by wind and splashing water. Gray leaf spot infects the corn leaves and the disease development is more likely to occur in warm and humid weather. When identifing Gray leaf spot look for leaf lesions that are long (up to 2 inches), narrow, rectangular, and light tan in color (coloring can turn more gray later on).
Eyespot: Caused by a fungus called Aureobasidium zeae. This fungus overwinters in corn residue and commonly occurs across the northern areas of the Midwest. These pathogens favor cool tempatures and wet and humid conditions. Eyespot is found more in corn that is in a corn on corn rotation with conservation tillage. Symptoms to look for are small, circular sports (1/16 inch to 1/8 inch diameter) with yellow halos on the leaves. These lesions later develop into an "eyespot", which is a tan spot surrounded by a brownish-purple ring and narrow yellow halo. These spots can be scattered on leaves but will often appear in patches that can join together to form large necrotic areas on the plant.
