The Purdue Turf Doctor app was developed by experts at Purdue University to help homeowners and land managers diagnose and address turfgrass problems caused by a variety of factors including weeds, insects, diseases, nuisance animals and abiotic stress. Turfgrass management professionals and garden center personnel can also use this app to improve communication with their customers. Information in this app is most useful in the Midwestern and Eastern United States, but may also be useful for diagnosing and managing turfgrass disorders in other regions of North America.

The hex bug

This is a great app for people who like to manage their own lawns. It's very flexible and will use the inputs you provide to create a short list of possible problems and solutions. It also contains handy links to more in depth information available from Purdue turfgrass scientists. About as good as it gets for taking the guess work out of diagnosing lawn problems.
