Late blight has not been reported in ND, MN or MB in 2019, but late blight severity values (DSV’s) in all potato growing areas have exceeded 15, the critical risk value at which late blight infection will occur if inoculum is present.

Identifying Herbicide Injury in Potato Production

Identifying Herbicide Injury in Potato Production

In this article I will explain and show specifically what the responses of potato plants are to some common modes of action. Understanding what the mode of action is can help narrow down the type of herbicide and how it can affect plant and tuber growth. I discuss some common translocating herbicides I often observe when determining injury in potato plants and tubers. They are, ALS-inhibitors, growth regulators, and EPSP synthase inhibitor (glyphosate).

Blightline for 2019: Potato Blight App

Blightline for 2019: Potato Blight App

Last year, the NDAWN Potato Blight app was launched to help potato growers have more accurate late blight and early blight notifications for individual fields. After some updates, we are excited to let you know that the NDAWN Potato Blight will be the key resource for late blight and early blight predictive models for the 2019 growing season. In addition to North Dakota, we expect this app to be available for Minnesota growers in 2019.

ND8068-5Russ 2018 Research Results

ND8068-5Russ 2018 Research Results

The breeding process for potatoes takes a long time, typically 10 to 15 years. However, after new varieties are released potato growers often do not understand how to best grow them because every potato variety responds differently. ND8068-5Russ responded well to high nitrogen rates, early in the season. Future studies should focus on higher nitrogen rates applied early in the growing season.
