Late blight spore trapping network report, August 26-September 9
This is the last late blight spore trap report for 2019. No late blight has been found in the spore traps in Minnesota and North Dakota. The number of spore traps being delivered to the lab have decreased because of the end of the growing season. The traps from August 26 to September 2 found no late blight spores (Figure 1). The week of September 2 – 9 also 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. If there are comments on this project or if you’d like to host a trap on your farm in the future, please email me.
