Potato rot nematode
Rotting and discoloration of subterranean plant tissue. In potatoes, early infection can be detected by small white spots underneath the potato’s skin. As the disease progresses, these spots become larger and darker with a spongy or hollow appearance.Tubers develop sunken areas and the skin becomes dry, cracked, and detached from the underlying flesh. There is further discoloration at this stage that is often due to secondary invasions of fungi, bacteria, and free-living nematodes. Above ground symptoms are usually not seen, although heavily infected plants are often weaker, smaller and can have curled or discolored leaves.
