'The complex association between powdery scab and Potato Mop-Top Virus (PMTV) creates a scientific agronomic puzzle that makes managing the 2 diseases difficult'. Read more about this in Potato Grower's September 2025 issue (Page 34)! Link in Bio!

Symptoms of virus can look similar in potato tubers. Always a good idea to have tubers tested. Unfortunately, this sampleĀ hit the trifecta! Tobacco Rattle Virus, Potato Mop top Virus and PVY-NTN. Many conditions to manage; but, our researchers are working to help minimize losses.

The PVY demonstration plots showed that certain varieties showed very strong symptoms when infected with PVYO, while others showed very little to no symptoms when infected with PVYO, PVYNWi and PVYNTN. Read more about it in our newsletter available at https://t.co/DVfHzlF5A1

Mop-Top is a virus that infects potatoes and causes the formation of a powdery scab. Kylie Grimm and Richard Quick wrote an article Potato Country's February 2025 issue discussing the impact this virus may have on commercial growers. Link in Bio!

Molecular markers associated with resistance genes have been useful in rapidly identifying and incorporating PVY resistance into potato breeding clones having potential for release as new PVY-resistant potato varieties. Read more about it in our newsletter. Link in Bio!

Payette Russet was deemed fully PVY-resistant or completely immune to PVY within the boundaries of the U.S. and even in North America. Read more about it in our newsletter available at https://t.co/DVfHzlF5A1

Currently, complete resistance to PMTV does not exist in the widely grown russet varieties. Resistance to PMTV needs to be incorporated into new varieties but resistance to the virus and symptoms must be found. Read more about it in our newsletter. Link in bio!
