Powdery Mildew disease on Gold Nugget cherry tomatoes
{"Image ImageDescription": "Powdery Mildew disease on Gold Nugget cherry tomatoes in western Washington, USA.  Three types of powdery mildew fungus plague tomatoes: Oidium neolycopersici, Erysiphe orontii, and Leveillula taurica. Fungi are spread by airborne spores, transported by wind or pests, which land on leaves and germinate. Powdery mildew needs living plant tissue in order to grow, but the fungi do not directly \u201ckill\u201d the tomato plants. Rather, they feed on the tomato plant\u2019s cells. This \u201cpowdery mildew\u201d (from which the disease gets its name) grows as thin layers on tomato leaf surfaces. \n\nThree factors make tomato plants succumb to powdery mildew: environment (humidity or wet leaves), onset date (the earlier in the season, the more difficult controlling mildew), and treatment (the sooner, the better).", "Image Make": "Canon", "Image Model": "Canon EOS-1Ds Mark III", "Image Orientation": "Horizontal (normal)", "Image XResolution": "72", "Image YResolution": "72", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "Adobe Photoshop CS6 (Windows)", "Image DateTime": "2013:05:05 16:12:01", "Image Artist": "Janet Horton", "Image Copyright": "\u00a9 Janet Horton", "Image ExifOffset": "1088", "Thumbnail Compression": "JPEG (old-style)", "Thumbnail XResolution": "72", "Thumbnail YResolution": "72", "Thumbnail ResolutionUnit": "Pixels/Inch", "Thumbnail JPEGInterchangeFormat": "1730", "Thumbnail JPEGInterchangeFormatLength": "10813", "EXIF ExposureTime": "1/45", "EXIF FNumber": "8", "EXIF ExposureProgram": "Aperture Priority", "EXIF ISOSpeedRatings": "320", "EXIF ExifVersion": "0221", "EXIF DateTimeOriginal": "2012:10:10 14:49:20", "EXIF DateTimeDigitized": "2012:10:10 14:49:20", "EXIF ShutterSpeedValue": "5491853/1000000", "EXIF ApertureValue": "6", "EXIF ExposureBiasValue": "1/2", "EXIF MaxApertureValue": "5", "EXIF MeteringMode": "Pattern", "EXIF Flash": "Flash did not fire, compulsory flash mode", "EXIF FocalLength": "135", "EXIF ColorSpace": "sRGB", "EXIF ExifImageWidth": "433", "EXIF ExifImageLength": "650", "EXIF FocalPlaneXResolution": "1872000/473", "EXIF FocalPlaneYResolution": "83200/21", "EXIF FocalPlaneResolutionUnit": "2", "EXIF CustomRendered": "Normal", "EXIF ExposureMode": "Auto Exposure", "EXIF WhiteBalance": "Manual", "EXIF SceneCaptureType": "Standard", "EXIF BodySerialNumber": "643144", "EXIF LensSpecification": "[28, 135, 0/0, 0/0]", "EXIF LensModel": "EF28-135mm f/3.5-5.6 IS USM"}
