Answer Details
An effective method of preventing viral diseases in crops is by planting resistant varieties. This means selecting crops that have been bred or genetically modified to be resistant to specific viral diseases. When these resistant varieties are planted, they are less likely to get infected with the virus, and even if they do get infected, the symptoms will be milder and the plant will be able to continue growing. This can help to reduce the spread of the virus and minimize crop loss.
Treating the seeds with fungicides, practicing crop rotation, and regular spraying of crops are all methods that can be used to control fungal diseases, but they are not as effective for preventing viral diseases. Fungicides are chemicals that are used to kill or control fungal diseases, but they do not work on viruses. Crop rotation involves planting different crops in a field each year to help control pests and diseases, but it may not be as effective for preventing viral diseases. Regular spraying of crops can help to control pests and diseases, but it may not be as effective for preventing viral diseases, especially if the virus is already present in the crop.
