Pea Cyst Nematodes are tiny, worm-like creatures that live in the soil. They're microscopic and cannot be seen with the human eye. Pea Cyst Nematodes most often target Peas, Beans and Vetches. In agriculture, they can cause severe yield losses. The nematodes can build up in the soil over the years, making it difficult to grow the desired crops successfully. The main symptoms include pale yellow leaves and stunted growth. On the roots, white cysts may be seen, with nodules failing to develop.

Attack the rooting systems of Peas and other legumes.


Identification: The cysts are probably the best way to identify the presence of the nematode. The cysts are creamy-white-yellow, turning brown when mature. They're shaped like lemons, measuring roughly half a centimetre.


Stunted growth. Roots develop studded white lemon-shaped cysts. Roots fail to develop nodules. They produce symptoms similar to Nitrogen deficiency in plants. Foliage turns yellow during the blooming stage.





Europe, Asia, some parts of North America and Africa

Biological treatment

Swapping out peas and beans and growing something completely different for a couple of years is recommended. Planting later when the soil has warmed can help. Buy plants from trusted retailers.
