Notable victims include corn, melon, pea, spinach, squash, celery and cucumber. Even a single infected seed can be a problem, as the virus can then be transmitted from the infected plant to those around it (aphids are a common vector) and can eventually spread right through a planting. Symptoms caused by the virus are mostly mosaic symptoms on leaves and leaf distortions. Overview Information Nasturtium is a plant. Depending upon the age, variety and health of plant, conditions and strain of virus, they may not have a significant effect on the plant (or perhaps slowing growth slightly) or they may cause stunting and severely reduce the harvest. Depending upon the age, variety and health of plant, conditions and strain of virus, they may not have a significant effect on the plant (or perhaps slowing growth slightly) or they may cause stunting and severely reduce the harvest. This disease is spread by aphids who basically inject the plants to get sap and spread it from plant to plant. Nasturtiums are rapidly growing annual or perennial plants. If any plants start to show the characteristic sign of mottled leaves, remove them immediately to reduce source of infection. Turnip mosaic virus (TuMV) was isolated from infested leaves of watercress (Rorippa nasturtium-aquaticum [Nasturtium officinale]) sold in markets in Venezuela.
