New App Available for Corn Ear Rot and Mycotoxin Management - (Charles Woloshuk)

A new app for Android OS developed by Purdue University and the University of Arkansas is now available to farmers to aid in identification and management of corn ear rots and mycotoxins. It can be found at Corn ear rots can cause losses due to yield and grain quality, and it can be difficult to properly store moldy grain. Additionally, some of the fungi that cause ear rots are able to produce mycotoxins as a byproduct of the infection process. 
This app helps users identify common ear rots and understand safe levels for use of grain affected by mycotoxins. The app also has information on ear rot management and properly storing moldy grain. Information ranges from handy tips for management to in-depth information on mycotoxins and conditions that favor ear rot development.  High quality images are available to help with ear rot identification, and links are provided to additional corn ear rot and mycotoxin management resources, found at An Apple OS version of the app is forthcoming.
This app is part of a larger project to understand ear rot pathogens and management of mycotoxins, “Integrated management strategies for Aspergillus and Fusarium ear rots of corn” and is funded by the United States Department of Agriculture-National Institute of Food and Agriculture: project 2013-68004-20359.
