What is a common method for controlling plant viruses?

Quarantine and inspection are critical strategies for controlling the spread of plant viruses. When crops are quarantined, they are effectively isolated from potentially infected plants, which helps prevent the transmission of viruses from one location to another. Inspection involves checking plants for signs of viral infections, allowing for early detection and management of any outbreaks before they can spread.

This method leverages the understanding that many plant viruses are spread by vectors such as insects or through physical means, including tools or machinery. By employing quarantine and inspection protocols, agricultural practices can minimize the risk of infection, thereby preserving crop health and yield. This preventative approach is essential in maintaining the integrity of agricultural systems, especially in regions where certain plant viruses are known to be prevalent.
