Miller Research LLC held its annual potato pest management seminar as a series of virtual meetings on February 16, 18, 23, and 25, 2021. Thank you to all who attended, participated, and provided feedback. Handouts of the PowerPoint presentations and links to the recordings are provided here.
Managing Fusarium Dry Rot
Options for managing Fusarium dry rot in the seed and at harvest, including seed handling, seed treatment, variety susceptibility, and post-harvest fungicide use.
Rhizoctonia Canker and Black Scurf
We discussed the importance of seed- and soil-borne inoculum and the effect of seed treatments and in-furrow fungicides on disease development.
Powdery Scab and PMTV
Symptoms of powdery scab and PMTV were discussed, along with the challenges associated with management recommendations for minimizing scab and PMTV symptoms.

Managing Pink Rot and Pythium Leak
Management options for pink rot and leak are presented. New research on the relationship between phosphite application and irrigation timing, along with optimal phosphite timing based on plant growth stage was also shown.

Foliar Disease Management and Managing Fungicide Resistance
We offered a virtual tour of the 2020 variety trial, showing the relative susceptibility of common russet cultivars to early blight/brown spot and white mold. We also discussed the strengths of different fungicide programs, emphasizing the importance of proper use to avoid the development of fungicide resistance.

I recently had the opportunity to speak at the Utah State University Vegetable IPM Winter Webinar Series (January 20, 2021). Nick Volesky and I talked about common insect and disease problems of potatoes. It wasn’t possible to discuss all diseases, or spend a lot of time on the diseases we did discuss, but we were able to give a thumbnail view of some common diseases. We briefly covered the following topics:
- The role of seed certification
- The importance of quarantines, eradication, sanitation, fertility, and proper irrigation
- Fusarium dry rot
- Rhizoctonia canker and black scurf
- Late blight
- Early blight
- White mold
- Pink rot
- Pythium leak
