Potato Pink Eye

Potato Pink Eye

This past year there were numerous cases of Pink eye. This is a physiological disorder most consistently caused by excessive moisture, warm temperatures, loss of foliar canopy and soil compaction. This syndrome gets its name because it can be expressed as a pinkish color and raised areas on the tuber surface. In some cases, Pink eye can develop into corky areas on the tuber skin, often described as elephant hide or corky patch.

Late blight spore trapping network report, August 26-September 9

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.

Blightline Sep 9, 2019

Blightline Sep 9, 2019

Late blight is NOT reported in ND, MN or MB. Some fields have been vine-killed or harvested already, but it is important to monitor fields that remain green for the next week or two. Late season outbreaks can result in tuber infection and secondary soft rot in the field or storage. Stay on the lookout for late season disease, especially near pivots, shelterbelts and other areas that stay wet for longer periods. It has been a good season so far with no late blight. This will be the last regularly scheduled NDSU Potato Blightline for 2019 unless late blight is found. We anticipate the Blightline continuing in 2020.

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.

More filters arrived for the week of August 5-12. An updated report for this time period found no late blight spores during this time period (Figure 1). The week of August 12-19 reported no late blight spores in the 14 traps that arrived (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.

Late blight spore trapping network report August 5-12, 2019

There were more filters that came in for the week of July 29 to August 5. An updated report for this time period found no late blight spores during this time period. The week of August 5-12 also found no late blight spores in the 9 traps reported. 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.

Aphid Alert, week ending August 9, 2019

Aphid Alert, week ending August 9, 2019

Aphid numbers took a big jump this week, with some important vector species (including Green Peach Aphid) making appearances. Cumulative seasonal catch increased by almost 50% with last week's catch from 214 last week up to 411 including this week's catches. Consequently the Vector Risk numbers rose sharply, doubling over last week.

Blightline August 12, 2019

Blightline August 12, 2019

NDSU Potato Blightline 12 August 2019. More good news. Late blight is NOT reported in ND, MN or MB. Late blight is reported in multiple locations in WI. The cool weather, closed rows, rain and morning dew are ideal conditions for late blight. The spore-trapping network in ND and MN has not yet detected spores of P. infestans, the cause of late blight. We commonly see first late blight infections in the field in early August, so it is important for all growers and consultants should be actively scouting fields for late blight, especially near pivots, shelterbelts and other areas that stay wet for longer periods.
