Each year farmers, crop scouts, industry agronomists, seed retailers, chemical company representatives, diagnostic labs, and research and extension staff can be faced with the challenge of correctly diagnosing crop production problems. The use of digital photographs taken with a camera, smart phone or tablet has become a widespread practice for many individuals involved with crop production issues. Digital images can be taken quickly and then immediately sent via email or posted on social media so that more specialists can provide a “virtual” diagnosis of an observed crop issue.
Speed, convenience, and the ease of contacting an appropriate specialist are some of the main advantages of using a “digital diagnosis” approach. However, experience has shown that too often the images sent are not adequate for making an accurate diagnosis. Some problems associated with a digital diagnosis may simply reflect issues occurring when pictures are taken.
In the PCDMN digital diagnosis article we have highlighted some of the more common mistakes we have made. Included in the article are tips to improve your plant disease photos, which will help facilitate our ability to digitally diagnose issues during the growing season. Finally, you have access to a vast resource of information related to digital photography. Reviewing this information will allow you to get the most out of your camera or smartphone for digital diagnosis of plant issues.
