Bacterial leaf streak
LEAF STREAK: Bacterial leaf streak appears as narrow lesions between or along veins of corn leaves. Lesions range from less than an inch to several inches long and may be yellow, tan, brown or orange.

Use social media to capture and track crop diseases

Twitter campaign encourages farmers to tweet corn and soybean diseases.

Farmers, agronomists, crop consultants and Extension specialists now have a place to collectively document and track corn and soybean diseases this growing season. The Twitter accounts @corndisease and @soydisease will be used to upload photos of crop diseases as they show up across the country.

This effort is part of the Integrated Pest Information Platform for Education and Extension (iPiPE). The hope is to use tweets of crop disease photos from around the country for future disease tracking and prevention purposes.

To help with the effort, take a photo of the crop disease when out scouting fields and then tweet the photo to @corndisease or @soydisease with the name of the disease, and the county and state it’s found in.

“Much like weather forecasting, we think this project can be used as a preventive strategy that farmers can use to get ahead of the ‘storm’ regarding crop diseases,” says Daren Mueller, associate professor and Extension plant pathology specialist at Iowa State University. “The information we gather from the Twitter campaign will be used to help predict trends in crop diseases and allow experts to provide the necessary management tools and information to farmers.”

Observations will be gathered and entered into a database to track crop disease trends across the country. At large, the iPiPE project is a coordinated, web-based, IT platform that enables the collection, management and delivery of observations, advanced derivative products, expert commentary and alerts on important pests.

“Our hope is to provide risk-based research, observations on target and endemic pests, and tools for timely management decision-making,” says Carl Bradley, professor and Extension plant pathology specialist at University of Kentucky.

So far this growing season, southern rust has been confirmed in the following states: Texas, Mississippi, Arkansas, Alabama, Georgia and Florida. Visit the @corndisease account for the most current updates and view the southern rust distribution map on the iPiPE website. Recent soybean disease findings include bacterial blight in Wisconsin and Iowa, and Rhizoctonia root rot in Iowa. Check @soydisease account for soybean disease updates.

The @soydisease Twitter account also will be giving away a free field guide each week to the first person who can correctly identify a soybean disease in a photo that will be posted each Wednesday.
