Cucumber mosaic virus (CMV) and Potato virus Y (PVY) have been described among the top five important viruses infecting vegetable species worldwide. They cause severe damages in fruits and cultivated plants. There is currently no available effective pesticide to control these viral diseases. Higher plants contain a wide spectrum of secondary metabolites such as phenolics, flavonoids, quinones, tannins, essential oils, alkaloids, saponins, sterols and others. Extracts prepared from different plants have been reported to have a variety of properties including antifungal, antiviral and antibacterial properties against pathogens. Tanacetum vulgare (Tansy) is native to Europe, Asia, and North Africa. It has many horticultural and pharmacological qualities. T. vulgare is principally used in traditional Asian and North African medicine as an antihelminthic, antispasmodic, stimulant to abdominal viscera, tonic, antidiabetic and diuretic, and it is antihypertensive. In our research we established antiviral effect of methanol extract from T. vulgare against CMV and PVY in tomato plants.
