How do you control plant viruses?
Disease control is based on two strategies: i) immunization (genetic resistance obtained by plant breeding, plant transformation, cross-protection, or others), and ii) prophylaxis to restrain virus dispersion (using quarantine, certification, removal of infected plants, control of natural vectors, or other procedures).
Can plant viruses be cured?
Management of Plant Virus Diseases Although there are virtually no antiviral compounds available to cure plants with viral diseases, efficient control measures can greatly mitigate or prevent disease from occurring. Virus identification is a mandatory first step in the management of a disease caused by a virus.
What is the best method to control plant disease?
Using resistant varieties is the most efficient way of controlling vegetable diseases. Make an effort to buy resistant varieties when they are available. Seed catalogs generally list resistant traits of the various vegetable varieties. The selection of planting date can be an effective tool for disease management.
Which plant is affected by the leaf curl virus?
Tomato yellow leaf curl virus (TYLCV) is a DNA virus from the genus Begomovirus and the family Geminiviridae. TYLCV causes the most destructive disease of tomato, and it can be found in tropical and subtropical regions causing severe economic losses.
Can plants carry viruses?
The answer is simply, no. Since plants are not a susceptible host for the virus that gives us the flu. VIruses are incredibly host specific, so we can’t get sick with a plant virus and plants can’t get sick with an animal virus.
Why is biological control better than control?
Biological control involves the use of another living organism to kill a pest. No chemicals are needed, there is no environmental contamination with pesticides, and the pests don’t become resistant to the control method.
What is Elisa test in plants?
Abstract. A novel form of indirect enzyme-linked immunosorbent assay (ELISA) has been devised for the detection of viruses in plants. The method uses protein A in two applications to sandwich antibody-antigen-antibody layers. The first applied layer of protein A prepares the plate for the coating antibody layer.
