Spud Scoop newsletter: Late blight severity, herbicide injury and aphid trap counts

NDSU Extension and University of Minnesota last week introduced a new growing season newsletter that will combine information of importance to potato growers. In the first issue of Spud Scoop, potato specialists cover late blight severity, herbicide injury and aphid trap counts.

Late blight has not been reported in ND, MN or MB at the time of the publication (July 3). The number of herbicide injury problems in potato have been more commonplace, according to Andy Robinson. Ian MacRae reports that aphid trap capture overall was very low with few aphids being recovered in traps.

Andy Robinson writes that injury from herbicides can be a result of soil carryover, herbicide residues in seed, or exposure of plants to herbicides. At this time of year, drift or tank contamination are concerns for herbicide injury. Symptoms of in-season exposure can be manifested as misshapen leaves, yellowing of leaves, elongated leaflets and cracking or malformed tubers.

The poster below demonstrates various herbicide injury symptoms, but will not demonstrate all symptoms, says Andy. “Determining if injury is caused by a herbicide or another source will be important in managing and marketing potatoes.”

If you would like a copy of the poster, you can download it at or pick one up at the NPPGA office, or contact Andy Robinson at [email protected]. Additionally, the July/August issue of the Valley Potato Grower magazine will have version of this poster that can be removed.
