Symptoms of potato virus X
You may not see any symptoms at all, besides a drop in tuber production, and your plants may look bushier than normal. Or, you may see chlorosis, dead spots in tubers, leaf crinkling, mosaic, ringspot, and smaller leaves. [Sadly, I was unable to find any photos I could use.]
Potato virus X management
Potato X disease is not transmitted by insects. It is only spread mechanically, on tools, clothing, and infected roots and tubers. If you avoid walking through infected areas and only use clean, disease-free seed potatoes, you should be able to prevent this disease. Crop rotation can help break the cycle.
Since potato X also appears on weeds in the same family, it’s a good idea to keep bindweed away from your susceptible crops. Heck, it’s always a good idea to keep bindweed out of your garden and landscape.
Some potato varieties, such as Atlantic, HiLite Russet, Norwis, and Sebago, show some resistance to PVX, so you may want to use them in your potato patch.
