If you are unsure of the nature of this disease, you may still be wondering “what is pea scratch virus? It is a virus that infects pea plants, causing them to develop purple streaks that spread along the entire stem. According to the information on pea scratch virus, it is not a rare disease. Scratching on plants is quite common in pea-growing areas, especially in late season pea crops.

PeSV is not the only virus that causes stretch marks on plants. Other viruses also cause the disease, such as western pea stripe virus, alfalfa mosaic virus, red clover vein mosaic virus and yellow bean mosaic virus.
