Late blight spore trapping network report August 19-26, 2019

No late blight has been found in the spore traps scattered in Minnesota and North Dakota. However, three spore traps from Manitoba reported finding late blight spores this week. An updated report from August 12-19 is provided in Figure 1. The week of August 19-26 reported no late blight spores found (Figure 2). As the legend in the map indicates, green dots indicate no late blight spores recovered at the marked locations and grey dots indicate no report.
